Buying Guide

Match bearing size to shaft and housing

Confirm bore, outer diameter, and width (e.g., 35x80x21mm class sizes) to ensure correct press or slip fit and proper load distribution

Choose the right seal type

Double rubber seals (2RS) protect against dust and light moisture for lower-maintenance use where minimal contamination is expected

Consider precision class and tolerances

For equipment requiring precision, select bearings with tighter radial runout and consistent manufacturing tolerances to maintain alignment and reduce vibration

Evaluate pack quantity for maintenance needs

Multi-piece packs (for example, 10-piece sets) can lower per-unit cost and simplify routine replacement schedules for fleets of light machinery

Check material and lubrication

Steel races with factory lubrication are standard for light equipment; verify that grease compatibility and corrosion resistance meet your operating environment
