Angular Contact Ball B. FAG 3319 -M

The 3319-M angular contact ball bearing from FAG Wälzlager (95 x 200 x 77.8 mm) is a double-row bearing with a brass cage that can withstand high radial and axial loads in both directions.

This 3319-M angular contact ball bearing is designed as a double-row bearing and is made from standard rolling-element bearing steel (100Cr6). The design combines two rows of balls within a single outer ring and requires less axial installation space than two separately mounted single bearings. The bearing has an inner ring with a bore diameter of 95 mm, an outer ring without a flange or groove with an outer diameter of 200 mm, and a total width of 77.8 mm. With standard radial clearance and tolerance class P0/PN (ABEC 1), this model is suitable for a wide range of industrial applications with standard fits.

What loads does the 3319-M double-row angular contact ball bearing support?

The double-row angular contact ball bearing accommodates combined loads involving high radial forces and alternating axial forces from both directions. Thanks to the contact angle of both rows of balls, the design also supports tilting moments. The open design without integrated seals allows for the direct supply of lubricating oil or rolling-element bearing grease. To ensure safe operation, an external housing seal is required to prevent the ingress of dirt particles or moisture into the raceways.

What are the distinctive features of the brass cage in the -M design?

The suffix ‘-M’ denotes a solid brass cage that guides the balls in both rows during operation. Brass cages offer exceptional mechanical strength against vibrations, shocks and high acceleration forces. Furthermore, the material exhibits favourable friction properties in the event of short-term lubricant shortages. With a permissible temperature range of -20 to +150 degrees Celsius, the 3319 -M angular contact ball bearing is suitable for demanding thermal operating conditions in continuous industrial operation.
