Tapered Roller Bearings FAG 32321

The FAG 32321 tapered roller bearing, measuring 105 × 225 × 81.5 mm, accommodates high radial and unilateral axial loads in industrial gearboxes.

The 32321 tapered roller bearing is a single-row rolling bearing designed for demanding mechanical assemblies. Its design combines tapered rollers with optimised raceways, enabling the guide surfaces to withstand high forces whilst maintaining dimensional stability. FAG offers this product as a complete tapered roller bearing in the standard design, comprising an inner ring with a roller cage and a separate outer ring. This split design significantly simplifies fitting into housings and onto shafts.

What is the FAG 32321 tapered roller bearing suitable for?

Design engineers primarily use this bearing size where high radial forces occur simultaneously with axial forces acting from one side. Typical applications include industrial mechanical gearboxes and gear stages in general mechanical engineering. As a single-row bearing can only accommodate axial forces from one direction, manufacturers usually fit a second tapered roller bearing in a mirror-image configuration to act as a counter-bearing. In this way, the shaft bearing arrangement absorbs alternating thrust forces without any play.

What are the advantages of a sheet steel cage and tolerance class P0?

The integrated sheet steel cage guides the tapered rollers on the inner ring and withstands mechanical loads. The permissible temperature range extends from –30 to +120 degrees, enabling operation in common industrial environments. Thanks to tolerance class P0 (equivalent to PN and ABEC 1), the component complies with the standard tolerances used in mechanical engineering. You can adjust the required operating clearance during installation via the axial preload.
