Deep Groove Ball Bearings FAG 6338 -M

The FAG 6338-M deep-groove ball bearing is a large, open bearing with a brass cage, with main dimensions of 190 x 400 x 78 mm.

The 6338-M deep groove ball bearing is a single-row radial ball bearing designed for heavy-duty machinery. With an inside diameter of 190 mm, an outside diameter of 400 mm and a width of 78 mm, this design can accommodate high radial loads and axial guidance forces in both directions. Manufactured from standard roller bearing steel 100Cr6, the rings and rolling elements offer high dimensional stability. As the component is of open design, it can be flexibly integrated into a planned housing lubrication system.

For which operating conditions is the 6338-M large bearing suitable?

Large-dimensioned rolling bearings of this size are primarily used in industrial mechanical engineering and in heavy-duty drive trains. Typical applications include heavy-duty gearboxes and industrial drives subject to high combined loads. Thanks to the solid brass cage, the bearing operates reliably even under vibration or with varying load directions. The 6338 -M deep groove ball bearing is designed for standardised bearing seats with a cylindrical seat.

What are the distinctive features of the brass cage and the open design?

The suffix ‘-M’ denotes the solid brass cage, which guides the rolling elements precisely. This cage design is engineered to withstand demanding mechanical stresses and dynamic load peaks. As the bearing is manufactured without integrated seals, the lubricant can be selected to suit the specific application. At ambient temperatures ranging from –20 to +150 degrees, the component retains its dimensional stability within the standard tolerance class P0.
