SplineXS Bore

Here are all the products that are compatible with the SplineXS shaft.

Pinions

Motor Pinions are smaller gears that are design to fit on a motor shaft. These gears use a wider 3/4" face width to help distribute torque over a wider area.

Center Distance

Some pinions are designed with a profile shift. This profile shift does two things:

  • Removes undercut on the tooth, making it stronger and easier to manufacture.

  • Increases the center distance of the pinion.

You must account for the increase in center distance when using these pinions. For example, a 10T gear on 12T center distance, will act like a 10T gear when you're doing ratio calculations but act like a 12T gear when you're doing center distance calculations.

Another way to think about it is if you have a 12T (on 12T spacing) gear driving a 60T gear, it can be replaced with a 10T (on 12T spacing) without having to change the center distance. With the 12T (on 12T spacing) gear, the ratio was 5:1 (60/12). With a 10T (on 12T spacing) gear, the ratio is 6:1 (60/10)
