Barrel Roller Bearings FAG 20210 -TVP

The FAG 20210-TVP spherical roller bearing is an open roller bearing with a 50 mm bore and a dimensionally stable polyamide cage designed for high radial loads.

The FAG 20210 -TVP spherical roller bearing features an angularly adjustable design to accommodate high radial loads. With key dimensions of a 50 mm bore diameter, 90 mm outer diameter and 20 mm width, this design automatically compensates for misalignment or shaft deflection during operation. This version has a standard radial clearance and complies with the standard tolerance class P0/PN (ABEC 1). As an open rolling bearing, its design allows for the flexible supply of grease or lubricating oil via the surrounding housing.

What is the 20210-TVP barrel bearing suitable for in cases of shaft deflection?

This single-row roller bearing is particularly suitable for bearing arrangements with static or dynamic misalignment between the shaft and housing. Thanks to its barrel-shaped rolling elements, the barrel bearing distributes high radial forces evenly across the raceways of the rings. The design reduces edge stresses at the ends of the rollers and absorbs sudden radial loads during operation, so that shaft deflection and misalignment are compensated for without impairing function.

What features does the polyamide cage offer in this open bearing?

The suffix ‘TVP’ denotes a solid polyamide cage, which reduces the weight of the rolling element assembly. The cage ensures quiet running of the barrel rollers and is suitable for operating temperatures ranging from –30 to +120 degrees Celsius. As the 20210-TVP barrel bearing is designed without an integrated seal, the lubricant can be selected as required. External seals at the bearing location provide protection against dirt particles and moisture.
