Deep Groove Ball Bearings SKF 6212 -2RS1

The SKF 6212-2RS1 deep groove ball bearing, measuring 60x110x22 mm and featuring a ground seal on both sides, offers protection against contaminants and moisture.

This single-row deep groove ball bearing 6212-2RS1 primarily withstands radial forces and also supports axial loads in both directions. The SKF design is made from standard 100Cr6 rolling bearing steel for the inner ring, outer ring and rolling elements. The sealing discs fitted on both sides ensure that the lubricant remains inside the bearing, whilst keeping dirt particles and splash water away from the raceways. The cylindrical outer ring has no flange or groove, allowing the component to be fitted flush into suitable housing bores.

What operating conditions does the 6212-2RS1 deep groove ball bearing require?

The design is suitable for rotating shaft bearings in general mechanical engineering and fixture construction subject to combined loads. In environments with dust or splash water, the sealed design proves its worth during operation. The integrated sheet steel cage reliably maintains the correct spacing between the rolling elements, whilst the design is rated for a temperature range of -20 to +120 degrees. The standard radial bearing clearance ensures proven clearance characteristics for standard fits.

What protection does the 2RS1 seal provide?

The suffix 2RS1 denotes two seals that seal on both sides, with their sealing lips resting against the contact surfaces of the inner ring. This design protects the deep-groove ball bearing against lubricant loss and the ingress of foreign particles and moisture. Designs featuring this seal type are primarily intended for installation locations where no additional external housing seal is present and where low maintenance requirements are a priority.
