Product Description

Tapered roller bearings have tapered inner and outer ring raceways as well as tapered rollers. They 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 α. The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factor e: the larger the value of e, the larger the contact angle.

 

Bearing 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.
Long service life
The crowned raceway profiles of basic design bearings and the logarithmic raceway profiles of  bearings optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends , and reduce the sensitivity to misalignment and shaft deflection compared with conventional straight raceway profiles .
Enhanced operational reliability
Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.


Consistency of roller profiles and sizes
The rollers incorporated in tapered roller bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution, reduces noise and vibration, and enables preload to be set more accurately.


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.
Running-in period with reduced temperature peaks
Tapered roller bearings typically have a running-in period, during which a conventional design tapered roller bearing experiences a significant amount of friction, resulting in wear. This effect is noticed as a temperature spike . With  tapered roller bearing designs, friction, frictional heat and wear are significantly reduced, provided the bearings are mounted and lubricated correctly.
Separable and interchangeable
Depending on the design, tapered roller bearings are separable and components of same-sized bearings are fully interchangeable. For example, single row tapered roller bearings are separable (fig. 5), i.e. the inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup). This facilitates mounting, dismounting and also maintenance inspection routines.
