Bearings are typically selected using L10 fatigue life calculations based on ideal
operating conditions. However, most bearing problems are not fatigue related,
but occur due to contamination, lubrication starvation, or other environmental
issues. As a result, our engineers have developed custom solutions to meet
the varying severity, operating parameters and maintenance regularity, such as
Reduced Maintenance and Custom Select.
Reduced Maintenance “RM”
Sealmaster Reduced Maintenance bearings are the result of a patented Tapered
Lands bearing race prole which means that critical lubricant is circulated more
efciently, while requiring no regular service intervals. The bearing are supplied
from the factory with a plug instead of a lubrication tting.
The outer land surface in a conventional bearing is parallel to the axis of the
inner ring. The Tapered Lands surface is tapered in a radial direction toward
the bearing race. This subtle yet crucial design change allows lubricant to more
easily ow back to the raceway. With improved bearing lubricant circulation
comes signicantly longer bearing service life. This improved circulation and
service life comes without any reductions in bearing radial or thrust capacities.
* For bearings that are maintained and relubricated on a regular basis, there is
no signicant difference in expected service life.
