Deep Groove Ball Bearings FAG 6320 -MA-C3

The FAG 6320 -MA-C3 single-row deep groove ball bearing, measuring 100 × 215 × 47 mm, combines radial load capacity with increased C3 bearing clearance and a brass cage.

The FAG 6320 -MA-C3 single-row deep groove ball bearing is designed for demanding industrial applications where radial forces and additional axial forces are present. With a bore of 100 mm, an outside diameter of 215 mm and a width of 47 mm, this version is one of the heavy-duty rolling bearings for larger shaft diameters. Manufactured from standard roller bearing steel 100Cr6, the design covers an operating temperature range from –30 to +150 degrees. As the bearing is of open design, it can be flexibly integrated into existing lubrication systems.

In which applications is the 6320 -MA-C3 deep-groove ball bearing used?

This rolling bearing is primarily designed to withstand high radial loads in industrial drives, gearboxes and heavy machinery bearing housings. Thanks to the combination of an open design and a robust internal structure, the bearing can withstand both constant and varying loads at medium to high speeds. Typical applications include heavy machinery, industrial gearboxes and large electric motors. Design engineers use this design where stable shaft guidance without a flange or groove on the outer ring is required and external lubrication is provided anyway.

What is the function of the brass cage and the C3 clearance?

The designation -MA stands for a solid brass cage with an external guide. This cage design guides the rolling elements with low vibration and is designed for heavy mechanical loads. The suffix C3 denotes a slightly increased radial clearance. This increased radial clearance compensates for thermal expansion that occurs between the inner ring and the outer ring during operation. This ensures that sufficient residual clearance is maintained in the case of tight fits on the shaft or in the housing. For correct installation, tolerance class P0 or ABEC 1 must be taken into account.
