MultiDirectional

Mecanum Wheels

Mecanum wheels allow savvy robot designers to create drivetrains capable of moving in any direction using a standard chassis shape. Simply power each wheel with a different motor and change the directions the wheels spin to get your robot to move in different directions!

These mecanum wheels were designed from the ground up to give the smoothest ride possible. Our construction method allows for a constant contact patch with a narrow profile. Each roller is tailored for the individual wheel diameter, and provides the correct, constant radius. We don't share rollers between wheel types -- these wheels aren't "almost round" -- they're actually round! This smooth-ride provides higher efficiency and reduces wasted power. This is especially important in mecanum drivetrains to provide smooth holonomic motion without high motor current draw.

Belts & Pulleys

Belts and Pulleys Basics

Common Terms

Pitch Diameter also known as PD is the circle that is formed while the belt and pulley are meshed together and which the belt rotates around. If you wish to find the PD, reference the formula below.

(Pitch x Number of T) ÷ π

The Outside Diameter also known as OD refers to the outside diameter of the pulley.

Pitch Length also known as PL is the length or circumference of a belt. If you wish to find the PL, reference the formula below.

T x Pitch

The Number of Teeth, T, is simply the amount of peaks that are around the pulley. If you wish to find T, reference the formula below.

PL ÷ Pitch

Calculating Center to Center

How to Use WCP 's Belt Distance Calculator

WCP now offers a built-in calculator to provide all our customers with piece of mind when designing with belts and pulleys. If you are interested in viewing our calculator or knowing how to use it, see below for more information.

Use this calculator to find the correct center to center distance for belts ()

You will need a few pieces of information when using the WCP Belt Calculator:

Belt pitch to be used
1. 3mm for GT2/GT3 belts
2. 5mm for HTD Belts

The Output from the calculator will give you the belt center to center as well as the tooth count for the closet belt to the values entered. It will also give you the information for one belt size higher and lower.

Center to Center Equations

The equation below shows the minimum center distance that should be used.

The equation below shows the center distance for equally sized pulleys.

The examples below are places where a looser belt may be beneficial. Subtracting center distance can help reduce the overall load of the system which in turn reduces motor load and power consumption.

First Stage Reduction: -0.000 to -0.003
Intake Rollers: -0.015 to -0.020
Conveyor System: -0.015" to -0.020"

Recommended Applications

GT2 Belts

First stage reductions
Motor to flywheel
Low load

HTD Belts:

Intake or conveyor systems
Drivetrains
Medium load

GT2 Belts and Pulleys

GT2 timing belts are intended for lower load applications such as the first reduction in a gearbox, or motor to flywheel. GT2 belts use a smaller pitch than HTD belts, which means you can use larger reductions in those tight fit areas of your robot.

Sprockets & Chain

Sprocket & Chain Basics

Common Terms

Pitch is the measurement from one roller chain pin to another. Popular chain sizes used throughout FRC are the #25 and #35, which have their respective pitches of 0.25" and 0.375"

Pitch Diameter also known as PD is the circle that is formed while the chain and sprocket are meshed together and which the chain rotates around. If you wish to find the PD, reference the formula below.

Pitch ÷ sin(180°/Tooth Count)

The Chain Clearance Diameter is the outer diameter of the sprocket while it is meshed with the chain. Knowing this is crucial when placing sprockets in tight places to ensure that no interference is being created. If you wish to find the Clearance Diameter, reference the formula below, along with an example equation for the sprocket shown above.

Pitch Diameter + Pitch

24T - #25 Sprocket

1.915 + 0.250 = 2.165

The Outside Diameter also known as OD refers to the size of the actual sprocket.

Calculating Center to Center

When deciding the placement and spacing of your sprocket and chain it is important to keep in mind that the Center to Center distance can be a fully custom measurement to ensure compatibility in your system, or can be decided through a pre-determined chain length.

The basic rule of thumb when deciding on a custom Center to Center distance is that it should be anywhere from 30-50 times the pitch of the desired chain for optimal usage and should not exceed 80 times the pitch.

Proper Tension

The examples below highlight different levels of chain tension, including chains that are too loose, too tight, and the recommended amount of slack for reliable performance in any subsystem.

An under tensioned chain can lead to inconsistent power transmission, causing the chain to skip teeth or derail from the sprocket entirely. This results in unreliable performance, excessive wear on both the chain and sprockets, and potential damage to surrounding components. Loose chains can also introduce backlash, reducing precision and control in your mechanism.

An over tensioned chain puts unnecessary stress on the chain, sprockets, bearings, and shafts. This added tension increases friction and wear, leading to premature failure of components. It can also reduce system efficiency by making it harder for motors to spin freely, ultimately impacting overall robot performance and reducing the lifespan of key parts.

A properly tensioned chain maintains just enough slack to allow smooth rotation while staying firmly engaged with the sprockets. This reduces wear on bearings and shafts, minimizes friction, and ensures reliable power transmission. With the right tension, the system runs efficiently, components last longer, and the risk of skipping or binding is greatly reduced. Resulting in consistent, high-performance operation.

Adding Chain Tensioner

Ensuring that proper tension is present in a sprocket and chain system is crucial for the sake of system integrity and performance. Achieving proper tension is a fairly simple task to do when using a chain breaker tool and tensioner offered through WCP. Such as the or the .

Implementing our chain tensioners into your system is a an easy task due to them having the necessary clearance holes for the roller pins. Use the chain breaker tool to partially remove the pin from the chain and lay your selected chain tensioner in place, then simply reset the pin back into place.

Idlers

Idlers are yet another way to ensure proper tension is present in a chain and sprocket system as they can be placed either on inside or outside of the chain loop to provide more contact with the sprocket and decrease slack. Adding an idler to the chain loop does not affect the ratio and can actually benefit performance if placed near the driving sprocket as it allows for more meshing.

Ball Bearings

Bearings constrain relative motion and reduce friction between moving parts.

WestCoast Products offers all the bearings most commonly used by FIRST ® teams, and also replacement bearings for all the "odd sized" bearings used in WCP gearboxes and assemblies.

Rounded Hex Bearings

Rounded Hex Bearings are designed to work with shafts that have a rounded hex profile, providing smoother rotation and improved alignment. Perfect for reducing friction in drivetrains, intakes, and other FRC mechanisms, these bearings make it easy to keep things running reliably under load.

Flange Type

Flanged Bearings

Flanged Bearings are a go-to solution for supporting rotating shafts while keeping everything securely in place. The built-in flange prevents the bearing from slipping through mounting holes, making them perfect for drivetrains, gearboxes, and any rotating assemblies in FRC robots.

Radial Bearings

Radial Bearings are built to support smooth, low-friction rotation in your FRC robot’s moving parts. Designed to handle loads perpendicular to the shaft, they’re ideal for high-speed applications and mechanisms with constant motion.

X-Contact Bearings

X-Contact Bearings are built to handle complex loads from multiple directions, making them ideal for rotating joints like arms and turrets. Their compact design and smooth operation help improve accuracy and reliability in high-performance robotics applications.

*3" & 3.5" X-Contact bearings available in Sealed and Non-Sealed versions.

Metric Bearings

Metric Bearings offer a precise, reliable fit for components designed around metric measurements. Whether you're working with imported parts or custom designs, these bearings provide smooth rotation and easy integration into your FRC robot. Available in a variety of sizes to match your build perfectly.

Flange Type

Specialty Bearings

Thrust bearings are perfect for handling axial forces in mechanisms like climbers or elevators, while needle bearings are ideal for high-load, low-profile applications where space is tight. Whether you're managing heavy loads or tight tolerances, these bearings offer smooth, reliable motion.

Bearing Type

Bushings

Bushings are lightweight, low-friction components that take the place of ball bearings in low-load, low speed scenarios. While they’re probably not suitable for flywheels, intake rollers, and drivetrains, we believe they’re the perfect fit for pneumatically-actuated joints and some low-load rotary joints, like simple arms and pivoting structures. We like bushings because they are:

Lightweight, which adds up in weight savings when replacing bearings with bushings
Extremely cheap, sometimes only 25% the cost of an equivalent bearing
Toleranced for a clean fit with commonly-used FRC stock

Bronze Bushings

Flange Type

Press Fit Drill Bushings

Press-fit drill bushings are commonly inserted into jigs and fixtures to guide drill bits and ensure accurate hole placement. They are a popular choice for applications where precision and repeatability are important, such as tread-cutting.

Sizes Available:

.159" Drill
.196" Drill
.25" Drill

Linear Bearings

These specialty bearings slide axially along a round shaft or tube’s length in order to achieve simple linear motion. Use a set of linear bearings to replace complex radial bearing stack setups and build sliding mechanisms with the strength and rigidity of FRC linear elevators for a fraction of the complexity!

While our linear bearings work with any shaft or tube material, we recommend thin-wall steel in heavy-use subsystems to decrease wear on the shaft while still maintaining strength and keeping weight low. Alternatively, having replacement shafts or tubes prepared for heavy-use subsystems utilizing linear bearings helps alleviate this problem.

Shaft Stock

WCP offers several different lightweight shaft stock options made from both 6061 aluminum (for tube axles) and 7075 T6 Aluminum (for high-strength hex shafts handling torsional loads). These shaft lengths are correctly toleranced such that they fit perfectly through bearings and hubs, without extra work.

Spacers and Standoffs

Aluminum Spacers

Our aluminum spacers are offered in a wide variety of lengths in order to speed up your spacer-making process, or even remove the manufacturing step altogether! Each spacer is made of ⅜” OD aluminum with a 0.196” diameter hole through its center, acting as a clearance hole for #10 hardware and a tap hole for ¼” hardware.

Length

Standoffs

Standoffs are like spacers, but the internal hole is threaded in order for a machine screw to thread into them for a strong and tight fit. Aluminum standoffs can be used to connect important components in your robot, and our variety of sizes gives you everything you need to make small gearboxes all the way up to large shooter hoods! The aluminum standoffs:

Are tapped 10-32 on both ends
Come in lengths of 2”, 3”, 4”, 5”, 6”, 7”, and 8”
Have a ⅜” hex profile so that users can use a wrench to hold the standoff while tightening screws

Gear Basics

Gears can be used to transfer motion from a spinning object to an object you want to rotate (ex: another shaft, a wheel, an arm, etc.). In addition to transferring motion, gears can be used to change the speed and torque inside a mechanism.

Speed and torque are inversely proportional. This means that as one increases, the other must be reduced. For example, if you decrease speed by 3x then torque will increase by 3x.

Changing Speed & Torque

You can change the speed and torque in a gear train by using different sized gears. The size ratio of two meshed gears will determine how much the speed and torque are changed. If two meshed gears are the same size, then speed and torque will remain the same.

Reducing Speed / Increasing Torque

In order to reduce speed and increase torque you must drive a gear with a smaller gear. For example, a 12T gear is driving an 84T gear. Since the 84T gear is 7x larger than the 12T gear driving it, the speed will be reduced by 7x while the torque will be increased by 7x.

Increasing Speed / Reducing Torque

In order to increase speed and reduce torque you must drive a gear with a larger gear. For example, a 48T gear is driving a 24T gear. Since the 24T gear is 2x smaller than the 48T gear driving it, the speed will be increased by 2x while the torque will be reduced by 2x.

Direction Of Rotation

Gears can also be used to change the direction of rotation. Gears spin in the opposite direction of the gear driving it. For example, if you have a gear train with two gears, the direction of rotation will be the opposite of the input. However, if you have three gears in a drivetrain, the direction of rotation at the output will be the same as the input.

When To Use Gears

There are pros and cons to using gears, so it's important to carefully consider your application before electing to use them in your design.

Here are some examples of applications when you should use gears:

The items you need to transfer motion to are close together. Generally speaking, gears are better at transferring motion between items that are close together.
You need a large speed reduction in a small space. Gears allow you to make a large amount of reduction in a relatively small space compared to timing belts and chain.
You need something to spin in opposite directions. Timing belts and chain will always spin in the same direction. So if you need two shafts to spin in opposite directions, gears are one of the easiest ways to do it.

When NOT To Use Gears

You need to transfer motion to something far away. Using a long gear train to transfer motion to something far away usually weighs more than just using timing belts or chain.
High shock loads. Shock loads are extremely high spikes in torque. These can be caused by a number of things like an arm crashing into something. Shock loads can produce spikes in torque many times higher than the mechanism would normally see. since gears transfer motion through a single tooth, they do not handle shock loads as well as timing belts or chain.

Calculating Center-to-Center Distance

Use this calculator for finding the correct center to center distance for gears ().

Extra Spacing

Sometimes you want to add extra spacing to center-to-center distance. The benefit of adding extra spacing to a center-to-center distance is to reduce gear wear and help the gearbox run smoother. However, adding extra spacing does increase backlash in the system.

Extra distance to add for center to center:

Exact Spacing: +0.000"
Standard Spacing: +.0015-.003"

In the context of gears, backlash is the amount a shaft can rotate before it drives a mating gear. In some applications, like a roller intake or conveyor, backlash doesn't greatly affect the performance of the the system.

However, in some applications like an arm, backlash can be very detrimental since it makes accurate position control much more difficult. A few degrees of backlash can result in inches of variance at the end of a long arm.

Tooth Spacing

Another way to think about gear spacing is the sum of the teeth in the gear ratio. You can change the gears in any gear ratio, as long as the sum of the two gears remains the same. For example:

Driving Gear

Driven Gear

Sum of Both Gears

Ratio

In the table above, you can see some examples of possible gears you can use on a gear ratio with "84 Tooth Spacing". As gear teeth are added or removed from the driving gear, the inverse is added to the driven gear, which keeps the sum at 84T.

20DP Gears

All 20DP WCP gears have a 14.5 degree pressure angle, and have the same 3/8" face width. This means it is easy to change gears in your design to find the perfect gear ratio without having to redesign your gearbox.

The specifications shown in the image below will be standard for all our 20DP Hex Gears.

Addendum Modified Gears

Addendum modifying gears is when you change the tooth profile to reduce undercut, which strengthens the tooth. When gears are addendum modified, it changes its Pitch Diameter, which changes the gear spacing. For example, an addendum modified 11T gear could be on 12T spacing. This means that the gear acts like an 11T gear when doing ratio calculations, but acts like a 12T gear when doing center-to-center calculations.

WCP sells a number of Motor Pinions that are addendum modified. This allows teams to change the tooth count on a motor pinion without having to change the corresponding gear.

Bevel Gears

The "standard" swerve drive bevel gear - now with black nitride coating for superior performance.

As time passes and experience grows within the FRC community, previously complicated build techniques are becoming more commonplace. Coaxial swerve drives, once attempted by only the most elite of teams, are now a well documented and accessible solution. Most coaxial swerve drives utilize a bevel gear pair as part of their design. After surveying FRC teams, we found almost everyone is using the same gear.

WCP now offers multiple Bevel Gears that are great for custom swerve modules!
