Bearing contamination control: dust, water, washdown and clean handling

Contamination control combines the bearing closure, surrounding seals, lubricant handling and the machine environment. A 2RS or shielded designation alone does not establish…

Bearing misalignment, shaft deflection and self-aligning designs

A self-aligning bearing can accommodate specified angular conditions; it does not make every shaft, housing or load error acceptable. Distinguish static seat misalignment from…

Bearing operating temperature: limits, measurement and comparison charts

There is no single normal or maximum temperature for every bearing. Compare a measured temperature with the exact bearing, lubricant, seal, cage and machine limits, and keep…

Bearing speed limits and minimum load: compare the exact operating case

A catalogue speed value belongs to stated bearing and lubrication conditions. It is not a guarantee that every assembly can run at that speed. Low load is not automatically…

Oscillating bearings: small movements, standby vibration and selection inputs

Back-and-forth motion is not equivalent to continuous rotation at a conveniently averaged rpm. Motion amplitude, reversal rate, load and lubricant replenishment at the contacts…

Temperature, materials and specialist environments

Existing application and comparison pages remain at their original addresses. Use them for high and low temperature, vacuum, corrosion, food processing and material selection; these requirements are not duplicated into new near-identical pages.
