Create a compact linear and rotary motion system for applications requiring complex, fast movements, such as robotics. The grooves on the ball splines transmit rotary power as ball bearings move smoothly and precisely along their length, even at high speeds.

Ball splines are alloy steel for high strength and wear resistance. They're hardened on the outside for additional wear resistance while the center is soft enough to absorb stress from shifting loads. Those with a step-down end have a shoulder near the end to stop gears, sprockets, and bearings.

Bearings have a retaining ring groove, so they can be positioned in your system with a retaining ring (not included). Bearings with a keyway include a machine key for attaching your load. Flanged bearings have a surface with mounting holes for attaching your load. Stainless steel bearings are more corrosion resistant than steel 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 are PTFE coated to reduce friction, so bearings slide smoothly and last longer. They’re stainless steel, so they won’t rust.

Bearings are plastic with a bronze shell, so they won't rust. Threaded bearings allow you to mount your load directly to the bearing. Anti-backlash bearings minimize the space (play) between the bearing and spline for more accurate, repeatable positioning.

Flanges work with threaded bearings to give you a surface with mounting holes to attach your load.

From one compact system, transmit linear or rotary motion or both at once (sometimes called spiral motion). Because of these different motions, these ball screw/splines and bearings create efficient, fluid movements in complex automated applications, such as pick-and-place robots.

The ball bearings move smoothly and precisely, even at high speeds. They're powered independently, so you can drive one bearing at a time or both together to coordinate movements.

The ball screw/splines are hardened on the surface, so they stand up to repeated motion. They’re also hollow, so you can run electrical wiring, compressed air tubing, coolants, or lubricant through their center.

A flange with mounting holes makes it easy to attach a load to these bearings. Create a compact linear and rotary motion system for robots and other applications requiring complex, fast movements, by combining them with ball splines. These bearings move smoothly and precisely even at high speeds along ball splines while grooves on the ball spline transmit rotary power. Clip a retaining ring (not included) into the groove on these bearings to position them in your system.

Splines are alloy steel for high strength and wear resistance. They're hardened only on the outside, so they stand up to repeated motion while keeping their center soft enough to absorb stress from shifting loads. Those with a step-down end have a shoulder near the end to stop gears, sprockets, and bearings.
