Key Features & Specifications

Basic dynamic load rating (Cₙ): approx. 14,200 N

Basic static load rating (C₀ₙ): approx. 6,800 N

Maximum reference speeds: up to ~14,000 rpm (grease) and ~16,000 rpm (oil) for certain variants.

The designation includes possible suffixes for seals/shields and clearances, for example: “62/22 C3”, “62/22 DDU”, “62/22 ZZ” etc

Typical Applications

This bearing is well suited for applications where:

Radial loads are present (primary use of deep groove ball bearings)

Some axial loads in both directions may also occur (deep groove designs permit axial load in both directions)

Moderate to high speeds are required, given its small size and high rpm capability

Space is constrained (compact size 22×50×14 mm)

Examples could include small motors, pumps, gearboxes, precision equipment assemblies, industrial machinery where a compact radial bearing is required.

Ordering / Specification Tips

Confirm the exact suffix (example: “62/22 ZZ” = double shield; “62/22 DDU” = double rubber seals) depending on your sealing/lubrication needs.

Check internal clearance required (normal, C3, etc.) if the application has high speed or temperature variation.

For high speed applications ensure lubrication is suitable for the rpm and environment.

Verify shaft fit and housing fit, including fillet radii, shoulder dimensions, to match the bearing’s installation requirements.

If replacing an existing bearing, ensure the exact size 22×50×14 mm matches, and that the load conditions are similar or are accounted for.
