Product Description 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. Bearings have a retaining ring groove, so they can be positioned in your system with a retaining ring (not included). Flanged bearings have a surface with mounting holes for attaching your load.
