Barrel Roller Bearings FAG 20228 -MB

The 20228 -MB spherical roller bearing from FAG Wälzlager, measuring 140 x 250 x 42 mm and featuring a brass cage, provides reliable guidance under high radial loads and shaft deflections.

The 20228 -MB spherical roller bearing is a single-row, angular-contact roller bearing designed for demanding industrial applications. The barrel-shaped rollers run on a hollow-spherical outer ring raceway, enabling the bearing to automatically compensate for misalignment and shaft deflection. Manufactured to the standard tolerance P0/PN (ABEC 1), this design is suitable for conventional shaft mountings in mechanical engineering where high radial forces must be reliably absorbed.

When is the 20228-MB barrel bearing used?

This rolling bearing is primarily installed where alignment errors between the housing and the shaft, caused by manufacturing or load factors, need to be compensated for. Typical applications can be found in general gearbox and heavy machinery construction. Compared to rigid roller bearings, the spherical geometry counteracts harmful edge pressures at the ends of the rollers. Thanks to its solid brass cage, this bearing is also suitable for operating conditions involving vibrations, oscillations or high continuous temperatures.

What are the characteristics of the version with a brass cage?

The suffix ‘MB’ denotes a guided solid brass cage, which offers high thermal and mechanical load-carrying capacity. In combination with the open design, this bearing allows operating temperatures ranging from –30 to +200 degrees. As there are no integrated seals, you can flexibly integrate the bearing location into existing lubrication systems. The standard radial bearing clearance ensures proven clearance characteristics for standard fit conditions.
