Tapered Roller Bearings SKF 33118

The SKF 33118 single-row tapered roller bearing, measuring 90x150x45 mm, accommodates combined radial and axial loads in industrial gearboxes and shaft guides.

The SKF 33118 tapered roller bearing is designed as a single-row rolling bearing to specifically accommodate combined radial and axial loads. With an inner diameter of 90 mm, an outer diameter of 150 mm and a width of 45 mm, this design is suitable for medium to heavy-duty industrial applications. Manufactured to SKF’s Explorer performance class, in combination with the robust sheet steel cage, it ensures high dimensional stability during operation. As a complete tapered roller bearing, the product comprises the outer ring, the inner ring and the associated roller cage.

In which assemblies is the 33118 tapered roller bearing used?

Design engineers and maintenance technicians primarily use the 33118 tapered roller bearing in gearboxes and in shaft and axle bearings in mechanical engineering. The tapered rolling elements simultaneously transmit high radial forces and single-sided axial forces, enabling precise guidance of rotating shafts.

Typically, the bearings are mounted in pairs in a mirror-image configuration to support axial forces acting in opposite directions. Thanks to the standard tolerance class P0 or ABEC 1, the component fits precisely into standardised housing seats and shaft shoulders.

What distinguishes the Explorer design with a sheet steel cage?

SKF’s Explorer specification features a tailored internal geometry and optimised raceway surfaces. The integrated sheet steel cage keeps the rolling elements in an orderly arrangement even during high acceleration, thereby minimising wear. Furthermore, the bearing operates within a temperature range of –30 to +120 degrees Celsius, enabling its use under operating conditions with fluctuating temperatures. As the inner and outer rings can be fitted separately, installation into the housing assembly is quick and efficient.
