Deep Groove Ball Bearings SKF 6301

The SKF 6301 deep groove ball bearing is an open, single-row radial ball bearing measuring 12 × 37 × 12 mm, designed for a wide range of industrial applications.

The 6301 deep groove ball bearing is one of the most commonly used single-row rolling bearings for rotating shafts. With a bore of 12 mm, an outside diameter of 37 mm and a width of 12 mm, this design primarily withstands radial loads. The groove geometry also allows axial loads to be transmitted in both directions. Manufactured from standard 100Cr6 rolling bearing steel and fitted with a sheet steel cage, the SKF Explorer version is suitable for a temperature range of -20 to +120 degrees.

What is the 6301 deep groove ball bearing suitable for?

This rolling bearing is predominantly used in shaft mountings that absorb radial forces at moderate speeds. The design has proven its worth in general mechanical engineering and equipment manufacturing for compact shaft diameters. As the outer ring has no flange or groove, the bearing can be press-fitted flush into cylindrical housing bores. The standard radial bearing clearance provides sufficient operating clearance for use under normal operating conditions.

What should be borne in mind with the open version of the 6301?

As an open bearing, the component has no integrated sealing washers. Lubricants reach the rolling elements and raceways unimpeded, allowing flexible lubrication via an oil circuit or external lubrication points. This design requires a clean installation environment or external housing seals to prevent the ingress of dirt particles. With tolerance class P0 (ABEC 1), the bearing complies with standardised specifications for industrial applications.
