FEATURES AND BENEFITS
Sealmaster Paver Bearings have been developed in conjunction with original equipment manufacturers and features vary by part number.
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.
NOMEX* SEAL WITH FLINGER The Nomex seal provides a high temperature, tight labyrinth seal which retains lubrication and acts as a filter to exclude contamination. The external stamping is a flinger which shields the felt from large contaminants and directs them away from the sealing surface.
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 first barrier against abrasive asphalt.
ROTATING SHIELD The black oxided shield is fixed 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.
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. "
