About Linear Bearings

Bearings are for use with round end-supported shafts. All have end seals to keep lubricant in and dirt out.

Fixed-alignment bearings are for use where shaft misalignment is unlikely.

High-Load Mounted Linear Ball Bearings

Designed to handle heavy loads, these bearings have the highest load capacities of any mounted linear ball bearings we offer. They are for use with round end-supported shafts. End seals keep lubricant in and dirt out.

Self-aligning bearings compensate for shaft misalignment.
