Deep Groove Ball Bearings SKF 6313

The 6313 single-row deep-groove ball bearing, measuring 65 × 140 × 33 mm, accommodates both radial and axial loads in industrial shaft mountings.

The 6313 deep groove ball bearing is an open, single-row rolling bearing made from standard bearing steel (100Cr6) in the SKF Explorer design. The bearing has a bore of 65 mm, an outside diameter of 140 mm and a width of 33 mm. Designed for a wide range of radial loads and moderate axial forces in both directions, a sturdy sheet steel cage guides the rolling elements evenly. With standard radial clearance and tolerance class P0/PN (ABEC 1), this component is suitable for a wide range of industrial shaft mountings.

What is the 6313 deep groove ball bearing suitable for in industrial plant?

The 6313 deep-groove ball bearing is primarily suitable for rotating shaft arrangements with a cylindrical bearing seat where combined loads occur. This design is recommended wherever high speeds and precise shaft guidance are required.

Thanks to the Explorer design, the bearing features optimised contact geometries on the raceways and balls. The permissible temperature range of –20 to +120 degrees enables its use in standard environments within general drive technology as well as in conventional mechanical engineering.

What are the distinctive features of the open design of the 6313 bearing?

The open design, without sealing washers, allows direct access to lubricant via an existing oil or grease system within the housing. An external housing seal must be fitted to keep contaminants away from the raceways.

The version with standard radial bearing clearance is designed for typical fit conditions and moderate operating temperatures. The outer ring has no flange or groove, allowing the bearing to fit flush into cylindrical housing bores.
