Spline Bearing Type
Sleeve Splines and Bearings
 |
Often used in wet and dirty environments, these sleeve splines and bearings create a compact linear and rotary motion system. The grooves on the splines transmit rotary power as the sleeve bearing moves freely along their length. Sleeve bearings don't have moving parts that can be damaged from dirt and debris. And they don't need to be lubricated, making them overall lower maintenance than ball bearings.
Splines
 |
Splines are PTFE coated to reduce friction, so bearings slide smoothly and last longer. They’re stainless steel, so they won’t rust.

Flanges work with threaded bearings to give you a surface with mounting holes to attach your load.
Anti-Backlash Externally Threaded Bearings
 |
Anti-backlash bearings minimize the space (play) between the bearing and spline for more accurate, repeatable positioning.
Threaded bearings allow you to mount your load directly to the bearing.
