Linear Bearings for Spline Shafts
Grooved on the inside, these bearings rotate with your spline shaft as they move loads up and down its length. They have fixed alignment—use them where shaft misalignment is unlikely.
Ball bearings, also known as ball splines, create less friction than plain bearings, making them smooth and precise even at high speeds. However, they don’t produce as much rotational force. Choose them for robotic systems and other automated applications that require complex, fast movements.

Mounted Linear Bearings for Spline Shafts
Ready to mount on your linear motion spline shaft, these bearings come installed in a housing and have grooves that match up with the splines on your shaft. Because they’re splined, they transfer rotational force as they move loads up and down the shaft’s length. A flanged end makes them best for lifting and lowering loads on vertical shafts. All have fixed alignment—use them where shaft misalignment is unlikely.
