Barrel Roller Bearings FAG 20212 -TVP

The 20212-TVP spherical roller bearing, measuring 60 × 110 × 22 mm, can withstand high radial loads and automatically compensates for misalignment caused by shaft deflection.

The 20212 -TVP spherical roller bearing is a single-row rolling bearing with a spherical outer ring raceway, manufactured by FAG Wälzlager. With a bore of 60 mm, an outside diameter of 110 mm and a width of 22 mm, this component primarily absorbs radial forces. Thanks to its barrel-shaped rolling elements, the bearing adapts to angular misalignments between the shaft and the housing. It features standard radial clearance and a tolerance class of P0/PN or ABEC 1.

In which applications does the 20212-TVP barrel bearing compensate for misalignment?

Design engineers and maintenance technicians prefer to use this bearing on rotating shafts where load-induced deflection or misalignment occurs. The spherical raceway counteracts edge stresses on the rolling elements when the shaft shifts slightly under load. Typical applications include bearing arrangements subject to high radial forces where automatic angular misalignment compensation is required. As this is an open design, the component integrates into lubricated housing assemblies.

What advantages does the TVP polyamide cage offer in terms of design?

The suffix ‘TVP’ denotes a polyamide cage that ensures smooth running and low friction. This material limits the weight of the moving mass and withstands typical accelerations during operation. The operating temperature range is from –30 to +120 degrees Celsius. Due to the open design without integrated seals, lubricant is supplied directly via the surrounding bearing housing.
