SKF 61814-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 70x90x10mm

The SKF 61814-2RS1 sealed thin section deep groove ball bearing is intended for rotating assemblies where a large shaft bore must be accommodated without a bulky bearing housing. Its extra-thin 618 series geometry leaves only 10mm of radial section between the shaft and housing surfaces, making it particularly useful in space-constrained mechanisms. The single row raceway design accommodates radial loads and moderate axial forces in either direction, provided the bearing is correctly sized for the application. SKF catalogue data lists a basic dynamic load rating of 12.4kN, a basic static load rating of 13.2kN and a limiting speed of 4,300rpm. These figures are important when assessing load capacity and speed in applications where conventional, wider bearings would be unsuitable.

The 2RS1 contact seals protect both sides of the bearing, helping retain factory grease and restrict contamination without a separate lubrication system. Sealing introduces running friction, so temperature and continuous rotational speed should be checked. Normal radial internal clearance also requires careful attention to shaft and housing tolerances. Because the bearing rings are exceptionally thin, excessive interference fits or distortion during mounting can affect running clearance and service life. Correctly machined seats, aligned components and appropriate installation tools are particularly important for this bearing type.

Typical Applications:

Compact rotary and positioning mechanisms

Space-constrained automation equipment

Lightly loaded industrial rotating shafts

Precision handling and indexing assemblies

Specialised machinery with thin bearing housings
