Choosing a bearing starts with the actual load, direction, speed, temperature, environment and available space. Light or medium loads often suit ball bearings, while heavy or shock loads may require roller bearings.

Specify the correct internal clearance, grease, seal and precision class. Clearance changes after mounting because of interference fits and thermal expansion, so it must be selected together with shaft and housing tolerances.

BNJ offers one-stop bearing selection and sourcing support for standard, non-standard and application-specific requirements.
