Manufacturer Ratings

Load-rating symbols are printed as each manufacturer writes them in its own catalogue, so the same quantity can carry a different symbol from brand to brand.

Speed Ratings

Speed limits depend on sealing and lubrication, and definitions differ by manufacturer. The figures below are for the open version of this bearing. Always confirm the exact variant in the manufacturer's table.

Sealed and shielded versions such as 2Z or 2RS have their own pages; a machined brass cage writing gets its own ↳ row where the catalogue prints a different limit.
