About Linear Bearings

Linear Bearings for Spline Shafts

With a grooved inner diameter, these bearings are designed to work with splined shafts. Together, they transmit rotary power while allowing the bearing to move freely along the length of the shaft. All are for use where shaft misalignment is unlikely.

Also known as ball splines, ball bearings run with less friction than plain bearings, so they're smoother and more precise, even at high speeds. However, they don't transmit as much torque as plain bearings. They're commonly used for robotic systems and other automated applications that require complex, fast movements. Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.

Plain bearings have evenly sized and spaced splines for transmitting high rotational loads, such as in hydraulic systems, drivetrains, and machine tools. They don't run as smoothly or as fast as ball bearings, though. All meet ISO 14-A (formerly DIN 5463-A) to ensure they work with shafts that meet ISO 14-B.

Mounted Linear Bearings for Spline Shafts

A flanged housing with mounting holes connects these bearings directly to your system. They have a grooved inner diameter that's designed to work with spline shafts. Together, they transmit rotary power while allowing the bearing to move freely along the length of the shaft. Wide and flat, the flange is especially useful for lifting and lowering loads on vertical shafts. All are for use where shaft misalignment is unlikely.
