Electrically Insulated Ball Bearings
Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing. The ceramic balls generate less heat than steel balls, so they require lubrication less frequently. Shields keep out dust and contaminants.

High-Speed Linear Sleeve Bearings
A ceramic liner makes high speeds as well as rapid acceleration and deceleration possible. Bearings are for use with round end-supported shafts. They have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).

High-Speed Flange-Mounted Linear Sleeve Bearings
A ceramic liner makes high speeds as well as rapid acceleration and deceleration possible. The flange-mount design is good for vertical linear motion applications. Bearings are for use with round end-supported shafts and are self-aligning to compensate for shaft misalignment. End seals keep contaminants out.
