Deep Groove Ball Bearings SKF 6338 M

The SKF 6338 M deep groove ball bearing, measuring 190x400x78 mm and featuring a brass cage, provides a robust bearing solution for large industrial machinery.

The SKF 6338 M single-row deep groove ball bearing, as an open rolling bearing, can accommodate high radial forces as well as axial loads in both directions. Manufactured from standard 100Cr6 rolling bearing steel, this large bearing is characterised by its robust design, featuring a 190 mm bore, a 400 mm outer diameter and a width of 78 mm. In many industrial installations, this model is used where heavy shafts need to be supported. The design, which has no flange or groove on the outer ring, facilitates cylindrical housing mounting.

In which industrial applications does the 6338 M deep-groove ball bearing prove its worth?

Heavy machinery designs require bearings capable of withstanding high mechanical stresses. Thanks to its substantial dimensions, this bearing is suitable for industrial shaft support systems subject to high radial forces and axial loads on both sides. As this is an open bearing, it can be integrated directly into lubrication circuits using oil or grease. At operating temperatures between –20 and +150 degrees, the rolling bearing steel used retains its dimensional stability and ensures consistent concentricity.

What advantages does the brass cage offer in the M version?

The suffix ‘M’ denotes the solid brass cage, which guides the rolling elements with precision. Compared to standard sheet steel cages, brass withstands higher levels of vibration and shock loads, which promotes continuous operation in large bearings. Furthermore, the bearing has a standard radial clearance and complies with tolerance class P0/PN (ABEC 1). Before installation, adjust the fits of the shaft and housing to this standard tolerance to avoid excessive loss of clearance.
