Angular Contact Ball B. FAG 3320 -M-C3

The FAG 3320 -M-C3 angular contact ball bearing, with dimensions of 100x215x82.6 mm, offers a high load-carrying capacity for combined loads under thermal stress.

This double-row angular contact ball bearing 3320 -M-C3 from FAG simultaneously accommodates high radial and axial forces in both directions. Constructed from standard 100Cr6 rolling-element bearing steel and featuring two rows of balls, its design is equivalent to two mirror-image paired single bearings in a compact configuration. With a bore of 100 mm, an outer diameter of 215 mm and a width of 82.6 mm, this rolling bearing is suitable for demanding bearing arrangements in mechanical and plant engineering.

What is the 3320 -M-C3 angular contact ball bearing suitable for?

Design engineers primarily use double-row angular contact ball bearings where shafts need to be guided precisely within limited axial installation space. The bearing transmits radial forces and supports alternating axial forces. Typical applications include rigid mounting arrangements subject to combined loads and high tilting moments. Thanks to its open design without integrated seals, the bearing can be integrated directly into lubrication circuits using oil or grease.

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

The suffix ‘M’ denotes a solid brass cage, which reliably guides the rolling elements even under severe vibrations or rapid changes in speed. The designation C3 stands for a slightly increased radial clearance. This increased clearance compensates for operational thermal expansion between the shaft and housing without the bearing becoming stressed. The permissible temperature range is from -20 to +150 degrees Celsius.
