Barrel Roller Bearings FAG 20211 -K-TVP-C3

The FAG 20211 -K-TVP-C3 spherical roller bearing, measuring 55 x 100 x 21 mm, with a tapered bore and C3 clearance, is designed to accommodate high radial loads and allows for angular adjustment.

The 20211 -K-TVP-C3 barrel bearing from FAG Rolling Bearings is a single-row, self-aligning roller bearing designed to withstand high radial loads. Thanks to its barrel-shaped rolling elements, this roller bearing automatically compensates for misalignment and shaft deflection during operation. With key dimensions of a 55 mm bore, 100 mm outer diameter and 21 mm width, this open bearing complies with the P0/PN standard tolerance. The integrated polyamide cage guides the rollers quietly and is suitable for operating temperatures ranging from -30 to +120 °C.

What is the 20211 -K-TVP-C3 spherical roller bearing suitable for in operation?

This spherical roller bearing is primarily used in industrial applications where housing deflection or shaft misalignment may occur. Typical applications can be found in general mechanical engineering as well as in bearing arrangements subject to high radial loads and impact forces. As this is an open design, lubrication is provided by the surrounding system or housing. The design ensures smooth running even with dynamic shaft movements.

What do ‘tapered bore’ and ‘C3 clearance’ mean during assembly?

The designation ‘K’ indicates a tapered bore with a ratio of 1:12. You would normally mount the component directly onto a tapered shaft seat or use a shrink sleeve on cylindrical shafts. The increased radial bearing clearance C3 compensates for the reduction in radial clearance that occurs when the inner ring is press-fitted axially. It also compensates for operational temperature differences between the inner and outer rings, thereby preventing the rolling elements from seizing.
