Deep Groove Ball Bearings FAG 6320 -M-C3

FAG 6320-m-c3 deep-groove ball bearing with a brass cage and C3 clearance, designed for demanding industrial applications, with an outer diameter of 215 mm and a width of 47 mm.

The 6320-m-c3 deep groove ball bearing is a single-row rolling bearing made from standard bearing steel, designed to accommodate radial and axial loads in both directions. The open design ensures that lubricant reaches the rolling elements and raceways unhindered during operation. FAG manufactures this version with a cylindrical bore, an outer diameter of 215 mm and a width of 47 mm. Thanks to the solid brass cage, the design withstands high mechanical stresses during operation.

What is the 6320-m-c3 deep groove ball bearing suitable for?

This rolling bearing has proven its worth in industrial drives, gearboxes and heavy-duty electric motors where thermal influences or tight fits occur. Design engineers specifically use the open design in enclosed gearbox housings with oil circulation lubrication or central grease supply. The bearing is designed for operating temperatures ranging from –30 to +150 °C. It therefore reliably withstands demanding environmental conditions in mechanical engineering and industrial conveyor technology.

What are the advantages of a brass cage and C3 bearing clearance?

The suffix ‘M’ refers to the integrated brass cage, which guides the balls precisely and withstands vibrations and shock loads. The C3 specification denotes a slightly increased radial bearing clearance. This additional radial clearance compensates for the thermal expansion of the components when they heat up during operation. Furthermore, the C3 clearance compensates for any constrictions that occur when the inner ring is pressed onto the cylindrical shaft, thereby minimising the risk of the rolling elements becoming jammed.
