The 2.5" wide clamping bearing blocks are compatible with the WCP Cam (WCP-0882) in the 2" tall tube configuration, while all clamping bearing blocks are compatible with the Cam in the 1" tall tube configuration.

20DP Gear Compatibility

The Clamping Bearing Blocks can be used to make basic gear trains by stacking the blocks next to each other on any 2" tall tube.

Assembly Prep

Refer back to the Individual Components page to ensure that all necessary parts are located before starting assembly steps.

Tools Required For Assembly

• Allen Key - 1/8"

Basic Assembly

Step 1

Slide the Clamping Bearing Blocks onto the tube. Make sure the tube has a clearance hole or slot for the shaft before assembly.

Step 2

Thread the four #10-32 x 1.500" L Button Head Bolts through the clearance block and into the tapped block.

Motor Mounting

In order to mount a motor to the 2.5" Bearing Blocks, use the two .375" OD x .125" depth c-bore holes.

Clamping Features

1" and 2" Clamping

All Clamping Bearing Blocks are sized to clamp around any box tube that is 1" or 2" tall. In order to clamp around 1" tall tube, the blocks must be rotated onto their side as shown in the image below.

SplineXL Bore ID

All Clamping Bearing Blocks have a SplineXL ID. This means it is compatible with the WCP SplineXL Tube (WCP-0918).

C-Bores

Bearing Flange C-Bore

All Clamping Bearing Blocks come with a 1.4" OD x 0.0625" deep c-bore that can be used to trap the flanges of bearings or bushings.

Bolt C-Bore

The 2.5" width Clamping Bearing Blocks (WCP-0592 and WCP-0593) both come two 0.375" OD x .125" deep c-bores that can be used to bolt parts directly to the block.

Center Drop

Two blocks (WCP-0591 and WCP-0593) come with an offset output. This means that when mounted to a 2" tall box tube, the center of the SplineXL bore will be offset by 0.0625" from the centerline of the tube.

2" Bearing Block (Centered, SplineXL Bore) (WCP-0590)

2" Bearing Block (.06" Offset, SplineXL Bore) (WCP-0591)

2.5" Bearing Block (Centered, SplineXL Bore) (WCP-0592)

2.5" Bearing Block (.06" Offset, SplineXL Bore) (WCP-0593)

Gearbox Bearing Block (#10, 2" C-C) (WCP-0595)

Sliding Bearing Block (#10, 2" C-C) (WCP-0596)

The WCP Bearing Blocks provide a simple and easy solution to mounting bearings to a tube. Perfect for the "West Coast" style drivetrain, these bearing blocks provide multiple ways to accomplish the same goal: adding a slot to the tube for the more customizable Sliding Bearing Blocks, or simply clamping around the tube with the easier Clamping Bearing Blocks.
