Tapered Roller Bearings FAG 33220

The FAG 33220 tapered roller bearing (100x180x63 mm) is designed to withstand high combined radial and axial loads in demanding industrial drives.

The 33220 tapered roller bearing is a single-row roller bearing from FAG in a standard metric design. With a bore of 100 mm, an outside diameter of 180 mm and a width of 63 mm, this design is suitable for bearing arrangements subject to demanding load profiles. As a complete tapered roller bearing, the unit consists of an inner ring with a roller cage and a removable outer ring. The geometry of the tapered rollers enables the bearing to accommodate simultaneous radial and single-sided axial forces in industrial machinery and plant engineering.

What is the 33220 tapered roller bearing suitable for?

Design engineers and maintenance technicians primarily use the 33220 tapered roller bearing where heavy shafts are supported and high radial forces occur in combination with unidirectional axial forces. Typical applications include gearbox stages and conventional shaft bearings subjected to high combined loads. As a single tapered roller bearing can only absorb axial forces in one direction, in practice it is usually paired with a second bearing arranged in a mirror-image configuration. This creates a rigid and highly load-bearing support system for rotating assemblies.

What role does the sheet steel cage play in this tapered roller bearing?

The integrated sheet steel cage guides the tapered rollers precisely along the raceway of the inner ring and maintains the specified spacing between the rolling elements. This design is characterised by low weight combined with high mechanical strength. In conjunction with the specified temperature range of -30 to +120 degrees, the bearing operates reliably under standard industrial operating conditions. Furthermore, the design complies with the standard tolerance class P0/PN (ABEC 1), which ensures a dimensionally accurate fit on standard shafts and in commercially available housing bores.
