Deep Groove Ball Bearings SKF 6238 M

The SKF 6238 M deep groove ball bearing, with a 190 mm bore and a brass cage, offers a robust solution for large industrial bearings.

This single-row deep groove ball bearing, model 6238 M, primarily supports radial loads and guides the shaft axially in both directions. With dimensions of 190 × 340 × 55 mm, this model is classified as a large bearing for use in mechanical and plant engineering. The design is from SKF and is made from standard rolling-element bearing steel (100Cr6). As an open design without integrated sealing washers, this rolling bearing allows direct access to lubricant via the housing.

In which applications is the 6238 M deep-groove ball bearing used?

This bearing unit is primarily used in large industrial drives and heavy machinery mountings designed to withstand high radial forces. Thanks to its design, which has no flange or groove on the outer ring, the bearing can be fitted directly into cylindrical housing bores. The permissible temperature range extends from –20 to +150 degrees Celsius. This makes the bearing suitable for thermally demanding industrial environments, provided that the external lubrication system is adapted to the operating temperatures.

What are the distinctive features of the brass cage in this design?

The suffix ‘M’ denotes a solid brass cage. Brass is characterised by high resistance to vibrations, shocks and accelerations. In combination with the standard radial bearing clearance and tolerance class P0 (ABEC 1), the deep-groove ball bearing is suitable for drives with consistent operating temperatures. A suitable external housing seal prevents the ingress of dirt particles.
