Bearings
Outer Race With Tapered Lands
The Sealmaster ER Bearings Outer Ring is black oxided and comes standard
with a locating ring and lubrication groove and lubrication inlet. In addition,
they have the Sealmaster patented Tapered Lands bearing race prole which
means that critical lubricant is circulated more efciently, while requiring no
regular service intervals. 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 signicantly 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 signicant difference in expected life.
Features and Benefits
Single Lip Contact Seal
Single Lip Contact Seal consists of a nitrile rubber washer in metal shroud to
shield the lip from large contaminants. The seal is designed to balance drag
and protection in wet and dry environments. This can be specied by adding
the sufx C to the part number.
Additional Sealing Options can be found on pages G-103 to G-106.
Multiple Sealing Options
Felt Seal With Flinger
The standard felt seal provides a tight labyrinth seal which retains lubrication
and acts as a lter to exclude contamination. The external stamping is a inger
which shields the felt from large contaminants and directs them away from the
sealing surface. The design operates with less drag and less heat generation
than rubber contact seals.
