Barrel Roller Bearings FAG 20220 -MB

The 20220 -MB single-row spherical roller bearing from FAG Wälzlager, with a 100 mm bore and a robust brass cage, provides reliable guidance for demanding shaft mountings.

The 20220 -MB spherical roller bearing is an open, single-row roller bearing designed for applications with predominantly radial loads. This FAG Wälzlager roller bearing has the following main dimensions: 100 mm bore diameter, 180 mm outer diameter and 34 mm width. It is manufactured to tolerance class P0/PN or ABEC 1. Thanks to the spherical barrel rollers, the design automatically compensates for misalignment or shaft deflection during operation.

What is the 20220-MB barrel roller bearing suitable for in practice?

The bearing is primarily used in general mechanical engineering and in industrial drives. Typical applications include mountings where manufacturing-related misalignments occur between the housing and the shaft, or where the shaft deflects elastically under operational load. As the bearing effectively absorbs radial forces and allows for angular movement, it counteracts edge pressures on the roller bodies. The operating temperature range of –30 to +150 degrees allows for use in industrial environments subject to thermal stress.

What advantages does the solid brass cage offer in this bearing?

The suffix ‘-MB’ denotes a solid brass cage that guides the rolling elements precisely. Compared with sheet metal or plastic cages, brass is characterised by high strength and thermal resistance. As this is an open bearing without an integrated seal, the lubricant is selected to suit the operating conditions. External seals in the housing protect the bearing location from the ingress of contaminants.
