Angular Contact Ball B. FAG 3219 -M-C3

The FAG 3219 -M-C3 angular contact ball bearing, measuring 95 × 170 × 55.6 mm, with a brass cage and C3 clearance, offers a robust solution for combined radial and axial loads.

The FAG 3219 -M-C3 double-row angular contact ball bearing accommodates high radial forces as well as axial forces acting in both directions within a compact installation space. Due to its double-row design, the construction corresponds to two paired single bearings in an O-arrangement, yet requires less axial installation width. Manufactured from 100Cr6 rolling bearing steel to tolerance class P0 (ABEC 1), this open rolling bearing is suitable for demanding industrial drives. The combination of a brass cage and a slightly increased C3 bearing clearance ensures stable operation in thermally stressed assemblies.

What is the 3219 -M-C3 double-row angular contact ball bearing suitable for?

This double-row ball bearing is primarily used in bearing arrangements where combined radial and axial loads occur. Thanks to its robust brass cage, the unit is suitable for mechanically stressed applications involving vibrations. The open design allows for direct lubrication via the surrounding oil bath or a lubricant supply provided by the customer. The permissible temperature range extends from –20 to +150 degrees Celsius, enabling use at elevated operating temperatures.

What are the advantages of the brass cage and the C3 clearance in the 3219 -M-C3?

The suffix ‘M’ denotes a solid brass cage, which, compared to standard sheet metal cages, offers precise rolling element guidance and high mechanical strength. The additional designation C3 indicates an increased radial bearing clearance. This compensates for thermal expansion of the shaft and housing during operation and prevents internal stresses. As the bearing, with a 95 mm bore, 170 mm outer diameter and 55.6 mm width, is of an open design, protection against contamination must be provided by the housing design.
