Barrel Roller Bearings FAG 20314 -MB

The FAG 20314-MB spherical roller bearing with a brass cage can accommodate high radial loads at dimensions of 70 × 150 × 35 mm and compensates for misalignment with angular movement.

The FAG 20314 -MB spherical roller bearing is a single-row roller bearing with spherical rollers designed for demanding industrial applications. With a bore of 70 mm, an outside diameter of 150 mm and a width of 35 mm, this roller bearing is particularly suitable for heavy radial loads. Thanks to the spherical outer ring raceway, the bearing adjusts to shaft deflection with angular adjustment. FAG manufactures the components to standard tolerance P0/PN or ABEC 1.

When is the 20314-MB spherical roller bearing recommended in design?

Design engineers opt for the 20314 -MB spherical roller bearing whenever shaft deflection or misalignment between the shaft and the bearing housing needs to be compensated for. During operation, the barrel rollers automatically align themselves within the spherical outer ring raceway, which reduces edge pressure on the roller edges. Due to its open design without integrated seals, the component can be integrated into external lubrication systems, such as in pedestal bearing housings. It primarily absorbs high radial forces and is suitable for shock-loaded applications in industrial operations.

What are the characteristics of the brass cage in the 20314-MB barrel bearing?

The suffix -MB denotes a solid brass cage that guides the rolling elements. This cage design withstands mechanical vibrations as well as high temperatures within the permissible range of -30 to +150 degrees. The standard radial bearing clearance serves to provide the required operating clearance when shaft and housing tolerances are correct. As no sealing washers are fitted, users can flexibly select grease or lubricating oil to suit the operating conditions and seal the bearing location via the housing.
