Deep Groove Ball Bearings SKF 6322 M/C3

The SKF 6322 M/C3 deep groove ball bearing, with dimensions of 110x240x50 mm, a brass cage and increased C3 bearing clearance, provides a high-load-capacity bearing solution for heavy shafts.

The 6322 M/C3 deep groove ball bearing is an open, single-row radial ball bearing to tolerance class P0/PN (ABEC 1), made from 100Cr6 rolling bearing steel. With a bore of 110 mm, an outside diameter of 240 mm and a width of 50 mm, this roller bearing is suitable for industrial applications involving high speeds and thermal stresses. The manufacturer, SKF, fits this version with a solid brass cage that retains high dimensional stability even under vibration. As no sealing washers are fitted, the lubricant reaches the raceways unimpeded.

What loads and operating conditions can the 6322 M/C3 deep groove ball bearing withstand?

This large bearing primarily withstands high radial forces as well as axial guidance forces in both directions. Typical applications include heavy-duty industrial drives and rotating machine shafts subject to high loads. As there are no contact seals, no friction losses occur at the sealing elements within the bearing. Combined with a temperature range of –20 to +150 degrees, the design is suitable for oil-lubricated systems and relubricatable bearing arrangements.

When are a brass cage and C3 bearing clearance required?

The suffixes M and C3 indicate technical deviations from the standard design. The suffix M denotes a solid brass cage which, compared to standard sheet metal cages, withstands vibrations and impact loads. The C3 bearing clearance indicates a slightly increased radial bearing clearance as supplied. This increased operating clearance helps to prevent the rolling elements from seizing if the shaft and inner ring expand due to operational heat build-up or if fits reduce the radial clearance.
