Single Row Tapered Roller Bearing High Precision Tapered Roller Bearing

Tapered roller bearings are single row bearings of open design which are always adjusted against a second tapered roller bearing in a mirror image arrangement . The bearings are designed such that they reliably cover the extensive demands in relation to generally common requirements. For example, in order to improve the lubricant film formation and running characteristics, the sliding surfaces on the guidance rib of the inner ring, as well as the end faces and contact profile of the rollers, have been optimised. In addition, the high production accuracy allows the bearings to be adjusted against each other with high functional security. This in turn leads to improved operating characteristics and thus to a higher operational reliability. Tapered roller bearings are not self-retaining. As a result, the inner ring with the roller and cage assembly can be mounted separately from the outer ring. This gives simplified mounting of the bearings.

Advantages

Increased customer benefits due to X-life

These technical enhancements offer a range of advantages, such as:

• up to 20 % higher basic dynamic load ratings Cr

• a higher running accuracy and smooth running

• running with reduced friction and greater energy efficiency (reduction in friction up to 50 %, in the case of tapered roller bearings with a steep taper, up to 75 %)

• lower heat generation in the bearing

• higher limiting speeds

• lower lubricant consumption and therefore longer maintenance intervals if relubrication is carried out

• a measurably longer operating life of the bearings

Lower operating costs, higher machine availability

In conclusion, these advantages improve the overall cost-efficiency of the bearing position significantly and thus bring about a sustainable increase in the efficiency of the machine and equipment.
