Barrel Roller Bearings FAG 20211 -TVP

The single-row 20211 -TVP spherical roller bearing from FAG Wälzlager, measuring 55 x 100 x 21 mm, provides angular contact support for high radial loads.

The 20211 -TVP barrel roller bearing is a single-row roller bearing with barrel-shaped rolling elements for shafts with a diameter of 55 mm. Thanks to the hollow-spherical outer ring raceway, this design automatically compensates for misalignment and shaft deflection during operation. FAG Wälzlager manufactures this open bearing with an outer diameter of 100 mm and a width of 21 mm. This version features standard radial clearance and tolerance class P0/PN or ABEC 1, and is suitable for lubricated systems.

What functions does the 20211-TVP spherical roller bearing perform during operation?

The 20211 -TVP spherical roller bearing is suitable for designs where high radial forces are present and where manufacturing-related misalignments or shaft deflection need to be compensated for. The spherical raceway reduces edge pressures on the rollers and promotes even load distribution. Relevant applications include heavy-duty bearing arrangements with elastic shaft deflections. As an open bearing without integrated sealing washers, the design integrates the component directly into the ambient lubrication system.

What features does the TVP version with a polyamide cage offer?

The suffix ‘TVP’ denotes a solid polyamide cage. This material has a low weight and promotes quiet, low-vibration operation of the rolling elements. The component has a permissible temperature range of –30 to +120 degrees. In the case of open roller bearings, an external housing seal protects against the ingress of dirt and the escape of lubricant. The standard radial bearing clearance is designed for common mounting fits and standard operating temperatures.
