Barrel Roller Bearings FAG 20209 -TVP

The FAG 20209-TVP spherical roller bearing, measuring 45 x 85 x 19 mm and featuring a polyamide cage, reliably compensates for misalignment under heavy radial loads.

The 20209 -TVP spherical roller bearing is a single-row, angular-contact roller bearing designed for demanding industrial applications. Thanks to its barrel-shaped rolling elements and spherical outer ring raceway, this model automatically adapts to shaft deflection and misalignment. You receive a bearing unit from the manufacturer FAG Wälzlager, which is specifically designed for high radial forces. This version features a cylindrical bore of 45 mm, an outer diameter of 85 mm and a width across flats of 19 mm.

What is the 20209-TVP spherical roller bearing suitable for?

Design engineers primarily use this barrel-type bearing where high impact loads and misalignments between the shaft and housing occur. Typical applications include heavy-duty bearing arrangements subject to dynamic deflection. As the rollers are ground to a barrel shape, the pressure is distributed evenly across the raceways. This protects the bearing from premature fatigue caused by edge stresses when shafts deflect slightly under heavy operating loads.

What are the advantages of the TVP polyamide cage?

The suffix ‘TVP’ denotes a polyamide cage that precisely guides the barrel-shaped rollers. This material reduces the weight of the rolling bearing and ensures smooth, low-vibration operation at normal operating temperatures. Furthermore, the open bearing operates to standard tolerance class P0 (PN) or ABEC 1. It requires a suitable external housing seal and appropriate lubrication with grease or oil to ensure a long service life within the permissible temperature range of -30 to +120 degrees.
