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.
