SKF 62301-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 12x37x17mm

The SKF 62301-2RS1 extra-wide sealed deep groove ball bearing provides rotational support for smaller industrial shafts where a wider axial mounting profile is required. It shares the 12mm bore and 37mm outside diameter of the standard 6301 bearing, but its 17mm width is 5mm greater. This difference is important in machinery with precisely positioned housing shoulders, shaft spacers and retaining components. The single row deep groove raceways accommodate predominantly radial loads together with limited axial forces in either direction. Published specifications give a basic dynamic load rating of 9.75kN and a basic static load rating of 4.15kN. These figures should guide load and service-life calculations rather than assuming the wider construction automatically offers greater carrying capacity.

The 2RS1 rubber contact seals retain the factory grease and help restrict the ingress of dirt, moisture and fine particles. This is particularly useful in enclosed roller assemblies and compact machinery where frequent relubrication is impractical. The published limiting speed is 14,000rpm, although continuous operating suitability depends on applied loads, temperature and contact seal friction. Normal (CN) radial internal clearance requires suitable shaft and housing fits to maintain adequate operating clearance after installation. For replacement work, confirm the full 62301-2RS1 designation, including the 17mm width, as a standard 6301 is not a direct dimensional substitute. Mounting forces should be applied to the fitted ring rather than through the balls.

Typical Applications:

Compact conveyor drive and roller assemblies

Packaging and automated handling machinery

Enclosed miniature mechanical transmissions

Industrial guide roller and pulley mechanisms

Specialised equipment with 17mm-wide bearing seats
