Tapered Roller Bearings FAG 32228

The FAG 32228 single-row tapered roller bearing accommodates combined radial and axial loads in industrial applications, with main dimensions of 140 × 250 × 71.75 mm.

The 32228 tapered roller bearing is a complete standard-design rolling bearing from FAG. The design consists of an inner ring with a set of rollers and a separate outer ring. With a bore of 140 mm, an outside diameter of 250 mm and a width of 71.75 mm, this design is intended for high-load shaft mountings. The tapered rolling elements transmit loads via line contact, enabling the bearing to transmit high forces whilst maintaining a compact design. The integrated sheet steel cage keeps the rollers evenly spaced.

In which applications is the 32228 tapered roller bearing used?

Design engineers and maintenance technicians primarily use the 32228 tapered roller bearing in applications where high radial forces and single-sided axial forces occur simultaneously. Typical applications include industrial gearboxes and heavy-duty drive trains subject to high mechanical stress. As a single single-row bearing can only accommodate axial forces in one direction, it is usually fitted in a mirror-image configuration with a second tapered roller bearing. This paired arrangement creates a backlash-free, rigid bearing arrangement for rotating shafts.

What are the key considerations regarding the assembly and tolerance class of the 32228 tapered roller bearing?

This bearing complies with the standard tolerance class P0/PN or ABEC 1 and meets standard industrial accuracy requirements. As the inner and outer rings can be fitted separately, the separable design makes installation considerably easier. During assembly, care must be taken to ensure precise adjustment of the axial bearing clearance via the mating bearing. The permissible temperature range is from –30 to +120 degrees Celsius, limited by the thermal stability of the components. A suitable lubricant must be applied to ensure correct operation.
