Tapered Roller Bearings FAG 33114

The FAG 33114 tapered roller bearing (70x120x37 mm) can withstand high radial and axial loads and features a sheet steel cage.

The 33114 tapered roller bearing is a single-row roller bearing from FAG, designed to simultaneously accommodate high radial and axial forces in one direction. With key dimensions of a 70 mm bore, 120 mm outside diameter and 37 mm width, it conforms to the standardised design. The complete bearing consists of the inner ring with a guided set of rollers and the separate outer ring. This design is particularly suitable where rigid shaft mountings are required under defined operating conditions.

In which applications is the 33114 tapered roller bearing used?

The 33114 tapered roller bearing is typically used in gearbox designs and in general mechanical engineering where combined loads are present. Due to the tapered geometry of the raceways, the roller bearing transmits high radial forces as well as single-sided axial forces. As a single tapered roller bearing can only accommodate axial forces in one direction, a second counter-bearing is usually incorporated into the design.

What are the functions of the tolerance class and the sheet steel cage in the 33114?

This roller bearing is manufactured to tolerance class P0, which corresponds to the ABEC 1 standard tolerance and is designed for common fits in mechanical engineering. The integrated sheet steel cage guides the rolling elements and is suitable for a temperature range of –30 to +120 degrees Celsius. As the inner and outer rings can be fitted separately, installation is made easier. During installation, care must be taken to ensure the bearing clearance is set correctly.
