Tapered Roller Bearings FAG 32221

The FAG 32221 tapered roller bearing, measuring 105 × 190 × 53 mm, withstands high radial and unilateral axial loads in industrial drives.

The 32221 tapered roller bearing is a single-row roller bearing in a standard design for heavy mechanical loads. As a complete tapered roller bearing, it consists of an inner ring with a set of rollers and the corresponding outer ring. As the extended contact lines of the tapered rolling elements converge on the axis of rotation, this bearing handles combined forces without inducing internal stresses. The manufacturer, FAG, produces this component to the standard tolerance P0/PN (corresponding to ABEC 1), which ensures a dimensionally accurate fit on shafts and in housings.

In which configurations does the 32221 tapered roller bearing accommodate axial and radial loads?

Typical applications for this bearing include industrial gearbox construction and shaft mountings subject to combined loads. Single-row tapered roller bearings accommodate high radial forces as well as axial forces from exactly one direction. In practice, they are usually fitted in pairs, with a second bearing positioned in a mirror-image configuration to provide axial support. As the outer and inner ring assemblies can be fitted separately, the bearing can be easily mounted on 105 mm shafts.

What are the features of the sheet steel cage and the open design?

The integrated sheet steel cage keeps the tapered rollers spaced apart and guides them along the inner ring raceway. The roller bearing operates within a temperature range of –30 to +120 degrees Celsius and is suitable for standard industrial environments. As the design is open, grease or lubricating oil can reach the raceways directly. A specially designed external housing seal prevents lubricant loss during operation.
