Deep Groove Ball Bearings FAG 6322 -M-C3

The 6322 -M-C3 deep-groove ball bearing, with a 110 mm bore, brass cage and increased bearing clearance, ensures good concentricity under high radial loads and at higher operating temperatures.

The 6322 -M-C3 deep groove ball bearing from FAG is a single-row rolling bearing designed for heavy-duty industrial applications. With a bore of 110 mm, an outer diameter of 240 mm and a width of 50 mm, this bearing primarily absorbs high radial forces and also supports the shaft axially in both directions. Designed as an open bearing, its construction allows for free lubricant circulation within the housing and covers a wide temperature range from –30 to +200 degrees Celsius.

For which loads is the 6322 -M-C3 deep groove ball bearing suitable?

Industrial applications involving high radial forces and demanding thermal conditions constitute the field of application for this design. The combination of high-quality rolling-element bearing steel (100Cr6) and the flangeless cylindrical outer ring enables the bearing to be mounted in suitable housing bores. By eliminating abrasive cover plates, the assembly operates with low frictional resistance during continuous running. The bearing must be integrated into the lubrication system of the overall plant, for example via an oil bath or by relubrication with grease.

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

The suffix ‘M’ stands for a brass cage. This cage material guides the rolling elements with low vibration and is suitable for high accelerations and shock loads. The designation ‘C3’ indicates a slightly increased radial clearance compared with the standard version. This additional operating clearance compensates for thermal expansion when the shaft heats up more than the housing during operation. In the case of tight fits, the C3 clearance helps to prevent the balls from seizing up during operation.
