Product Description

Bearing Design

Standard cylindrical roller bearings feature a tapered bore (taper 1:12) for precise adjustment of the radial clearance. Thus the desired radial clearance or radial preload can be adjusted by axial displacement on the tapered shaft. Hybrid cylindrical roller bearings with rollers from ceramic material have been newly included in the product range.

Thanks to the use of ceramic rollers, they offer significantly improved characteristics in terms of bearing friction and wear.

 

This reduces the demand on the lubricant and leads to lower temperatures.

Consequently, higher speeds are permissible and the service life is extended to a significant degree. Furthermore, ceramic

rollers lead to increased static and dynamic rigidity and their lower thermal expansion coefficient defuses an increase in preload at elevated temperatures.

 

In the case of oil lubrication, attention has to be paid to their lower oil requirement in comparison with angular contact ball bearings.

The oil circuits have to be kept separate if these two bearing types are mounted side by side. Excess lubrication due to oil flow from the angular contact ball bearings has to be avoided as a sharp increase in bearing temperatures is to be expectedotherwise.

 

 

The bearings comprise solid outer rings without ribs, solid inner rings with three ribs and cylindrical roller and cage assemblies with solid brass cages. For optimum setting of the radial internal clearance, the inner ring has a tapered bore with a taper of 1:12. The cylindrical roller bearings can be dismantled and are therefore easier to fit and remove. Both bearing rings can therefore have an interference fit.

 

super precision cylindrical roller bearings are characterized by:

 

high speed capability

 

high radial load carrying capacity

 

high rigidity

 

low friction

 

low cross-sectional height
