Product Description

Single row tapered roller bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis to provide a true rolling action and therefore low frictional moments during operation. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle.

Features

• Low friction

The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. In addition, the bearings can better maintain preload and run at reduced noise levels.

• Enhanced operational reliability

Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.

• Rigid bearing application

A single row tapered roller bearing is typically adjusted against a second tapered roller bearing. By applying a preload, a rigid bearing application can be achieved.

• Separable and interchangeable

The inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup). Furthermore, the separable components are interchangeable. This facilitates mounting, dismounting and also maintenance inspection routines.
