Barrel Roller Bearings FAG 20214 -TVP

The 20214-TVP spherical roller bearing from FAG Wälzlager combines a 70 mm bore with an outer diameter of 125 mm and compensates for misalignment under high radial loads.

The 20214 -TVP spherical roller bearing from FAG Wälzlager is a single-row, angular-contact roller bearing with a spherical outer raceway. Thanks to this geometry, the roller bearing automatically compensates for misalignment and shaft deflection during operation. With main dimensions of 70 × 125 × 24 mm, the unit primarily accommodates high radial loads. This open roller bearing is a functional bearing component conforming to standard tolerance class P0/PN or ABEC 1.

In which installation scenarios does the 20214-TVP spherical roller bearing compensate for misalignment?

This barrel bearing is particularly suitable for bearing locations where operational misalignment of the shaft or manufacturing-related misalignment of the housing bores occurs. The design is used in rigid bearing arrangements subject to high radial loads, where elastic shaft deflection must be compensated for. The bearing compensates for angular misalignment without causing impermissible edge stresses. As this is an open design without seals, its use requires a protected, separately sealed bearing housing.

What are the key features of the TVP polyamide cage?

The TVP suffix denotes a dimensionally stable, solid cage made of polyamide. This thermoplastic material ensures reduced inertial forces and supports uniform guidance behaviour of the barrel-shaped rolling elements. In combination with the specified temperature range of –30 to +120 degrees, the bearing is designed for a wide range of industrial applications. When designing the bearing, the standard radial clearance must be taken into account, whilst the open design requires lubrication tailored to requirements directly within the housing.
