Paver Bearings
Rotating Shield
The black oxided shield is xed to the extended inner ring and precision
machined to run with a small clearance with the end cap. The shield resists
asphalt erosion and helps protect the inner sealing elements.
Ductile Iron End Cap
A tough, wear resistant end cap that helps keep asphalt from forcing its way
into the bearing. The ductile-iron, bolt-on end cap mates with the casting
providing the rst barrier against abrasive asphalt.
Self-Adjusting Washer
A conical-shaped mechanical seal is located directly behind the rotating shield
supplying the bearing with a third contamination barrier. The stainless steel
washer attaches to the bearing’s inner ring.
Features and Benefits
High Temperature Contact Seal
The double lip high temperature contact seal is the most popular design
used, some designs incorporate a high temperature single lip contact seal , or
combination of different seals for the front and back side of the bearing.
Sealmaster Paver Bearings have been developed in conjunction with original equipment manufacturers
and features vary by part number. Some common features are listed below.
Nomex* Seal with Flinger
The Nomex seal provides a high temperature, 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.
