Barrel Roller Bearings FAG 20205 -TVP

The 20205-TVP spherical roller bearing, with a 25 mm bore and an outer diameter of 52 mm, compensates for misalignment under high radial loads.

The FAG 20205 -TVP spherical roller bearing is a single-row, angular-contact roller bearing designed for demanding industrial applications. It primarily accommodates high radial forces and tolerates misalignment between the shaft and the housing. With its compact dimensions – a 25 mm bore, 52 mm outer diameter and 15 mm width – this design is suitable for confined installation spaces. The open design allows for a flexible choice of lubricant directly within the housing, whilst the standard tolerance class P0/PN ensures a dimensionally accurate fit on the shaft.

How does the 20205-TVP barrel bearing compensate for misalignment and shaft deflection?

The bearing automatically compensates for angular misalignment between the shaft and housing via its hollow-spherical outer ring raceway. The crowned barrel rollers adapt to misalignments without causing excessive edge stresses. Designs prone to deflection or misalignment benefit from this flexibility. Due to the single-row roller arrangement, the component primarily supports radial and impact forces, whilst axial loads are only absorbed to a limited extent due to the design.

What are the distinctive features of the version with a TVP cage?

The suffix ‘TVP’ denotes a polyamide cage. This material reduces the weight of the rolling element set and promotes smooth, low-friction operation. The bearing is designed for a temperature range of –30 to +120 degrees. This version features a standard radial clearance and tolerance class P0/PN (ABEC 1). As this is an open bearing without integrated seals, you must protect the bearing housing from contamination via the housing and select the lubricant to suit the operating conditions.
