Deep Groove Ball Bearings SKF 6313 -RS1

The SKF 6313-RS1 deep groove ball bearing, measuring 65x140x33 mm, offers single-row load-carrying capacity and single-side protection against contamination.

The SKF 6313 -RS1 deep groove ball bearing is a versatile rolling bearing for industrial applications. With a bore of 65 mm, an outside diameter of 140 mm and a width of 33 mm, the bearing primarily absorbs radial forces but also guides shafts precisely under moderate axial loads. Manufactured from standard 100Cr6 rolling-element bearing steel and fitted with a lightweight sheet steel cage, the design is suitable for demanding rotational applications in mechanical engineering. This version is supplied with standard radial clearance for regular installation situations.

What is the 6313-RS1 deep-groove ball bearing suitable for?

This single-row ball bearing is primarily used in rotating industrial applications and powertrains. Thanks to its flangeless cylindrical outer ring, the unit fits directly into standardised housing bores. The rolling elements support rotating shafts at operating temperatures ranging from –20 to +120 degrees. Design engineers make specific use of the open rear side where lubrication is supplied from inside the housing, whilst the sealed side prevents the ingress of foreign particles from the outside.

What is the function of the single-sided RS1 seal?

The single-sided sliding seal, made of synthetic rubber, effectively protects the interior of the bearing against dust and splash water. At the same time, the opposite side remains open, allowing for the circulation of housing oil or targeted relubrication. Before installation, check the required installation direction to ensure that the RS1 sealing lip faces the side exposed to contamination. As the bearing is manufactured to the standard tolerance class P0 and has standard bearing clearance, it complies with the usual specifications for standard fits in general mechanical engineering.
