Tapered Roller Bearings SKF 33206

The SKF 33206 tapered roller bearing accommodates combined radial and axial loads whilst maintaining compact dimensions of 30 × 62 × 25 mm.

The single-row tapered roller bearing 33206 is designed as a complete rolling bearing and consists of an inner ring with a set of rollers and a matching outer ring. The tapered rollers and raceways dissipate the forces acting on them via a defined contact angle. In this version, the model is part of SKF’s Explorer performance upgrade and features a dimensionally stable sheet steel cage. The component covers an operating temperature range of –30 to +120 degrees Celsius and complies with tolerance class P0/PN or ABEC 1.

In which bearing arrangements is the 33206 tapered roller bearing used?

This bearing is primarily used where high radial forces must be accommodated simultaneously with unilateral axial forces. As a single tapered roller bearing, by design, can only accommodate axial forces in one direction, in practice it is usually mounted in pairs with a second tapered roller bearing positioned in a mirror-image configuration. Thanks to its separable rings, the standard version can be specifically integrated into suitable housing designs.

What criteria are relevant when selecting bearing 33206?

For correct operation, the key factor is the correct setting of the axial bearing clearance or preload during installation. As the inner and outer rings can be mounted separately on the shaft and housing, installation requires precise alignment of the mating surfaces. The mounting dimensions of 30 mm shaft diameter, 62 mm housing bore and 25 mm overall width must be taken into account. The built-in sheet steel cage reliably guides the rolling elements within the specified temperature range of -30 to +120 degrees Celsius.
