WCP SplineXL Roller Hubs – Versatile Torque Transfer for FRC and Beyond

WCP SplineXL Roller Hubs are part of a system designed to work seamlessly with a wide range of applications, including feeder systems, intake systems, arm connections, and drive rails—ideal for FRC robotics as well as custom industrial solutions.

The WCP SplineXL spline profile was inspired by the farming industry, which has long used spline tubes in PTO applications. This ball-based spline profile allows for several key benefits:

• Easy to machine in-house

• Torque transfer via the rounded star profile

• Rounded shape supports future telescoping applications

• Ability to add a bearing or bushing to the ID

• Acts as a clocking feature for accurate and repeatable setups

This system has been long in the making and provides flexibility and strength for a variety of mechanical configurations.
