Angular Contact Ball B. FAG 3222 -M

The 3222-M double-row angular contact ball bearing, measuring 110 × 200 × 69.8 mm, accommodates radial loads as well as axial loads on both sides.

The 3222-M angular contact ball bearing from FAG is designed as an open, double-row rolling bearing for demanding bearing applications. Thanks to its two rows of balls, this bearing directly supports radial forces as well as axial forces from both directions. Manufactured from standard roller bearing steel 100Cr6, the design provides a solid basis for industrial applications with combined load profiles. The standard version, without a flange or groove on the outer ring, facilitates fitting into conventional housing bores.

What loads and mounting conditions determine the use of the 3222-M angular contact ball bearing?

Double-row angular contact ball bearings are used when radial forces act on a bearing arrangement together with alternating axial forces. Typical applications are found in mechanical engineering for shaft guides subjected to combined loads. Functionally, the internal geometry corresponds to two single-row angular contact ball bearings arranged opposite each other; however, it requires less axial installation space than two individual bearings. The 3222 -M angular contact ball bearing is suitable for rigid bearing arrangements where defined axial and radial guidance is required.

What properties does the brass cage of the -M variant offer?

The suffix ‘-M’ indicates a brass cage that guides the rolling elements precisely. Brass is characterised by good emergency running properties and mechanical strength, which is advantageous in the event of shock loads or vibrations. Furthermore, the bearing operates within a temperature range of -20 to +150 degrees. As this is an open design without an integrated seal, the lubricant and housing seal are selected to suit the operating environment.
