Barrel Roller Bearings FAG 20232 -MB

The FAG 20232 -MB spherical roller bearing can accommodate high radial loads with a bore of 160 mm, an outside diameter of 290 mm and a width of 48 mm.

The single-row 20232 -MB spherical roller bearing from FAG is an angular contact rolling bearing designed for heavy radial loads in mechanical and plant engineering. Thanks to its barrel-shaped rollers, this design compensates for misalignment and shaft deflection between the inner and outer rings during operation. This version features a cylindrical bore with a diameter of 160 mm, an outer diameter of 290 mm and a width of 48 mm. With the standard tolerance class P0 (ABEC 1), the bearing is suitable for standardised fits.

What is the 20232-MB spherical roller bearing suitable for in operation?

Designs featuring long shafts or flexible housing structures make specific use of the barrel bearing’s angularly adjustable raceway. The bearing primarily absorbs unilateral and shock-like radial forces, such as those encountered in heavy-duty shaft mountings or under dynamic radial loads. As the FAG roller bearing compensates for misalignment, it prevents edge pressure on the roller elements. Maintenance engineers and designers prefer to use this roller bearing at bearing locations where, due to the nature of the process, assembly inaccuracies or deflection under load occur.

What is the function of the brass cage in the 20232-MB barrel bearing?

The designation ‘MB’ indicates a solid brass cage that guides the roller elements precisely. Compared to plastic cages, this material withstands higher mechanical stresses, vibrations and operating temperatures between –30 and +200 degrees Celsius. As this is an open bearing without an integrated seal, you should select the type of lubricant and lubrication intervals to suit the ambient conditions. The component requires an external seal on the housing to prevent dirt and moisture from entering the raceways.
