Speed Ratings
Speed limits depend on sealing and lubrication, and definitions differ by manufacturer. The figures below are for this shielded version (6301-Z). Non-contact seals and shields run close to the open bearing. Always confirm the exact variant in the manufacturer's table.
Limiting speeds for a bearing with only one shield (Z) are those of the open bearing (SKF Rolling Bearings, PUB BU/P1 17000).
