Features & Benefits

• Sealmaster® mounted paver bearings with set screw locking are available in a wide variety of features:
• Various sizes depends on specific application
• Special part number system "PVR" prefix
• Designed for specific OEM paver manufacturers
• Patented bearing seal technology with four barriers (end cap, shield, washer, seal)
• Ductile iron end cap - a tough, wear-resistant end cap helps keep asphalt from forcing its way into the bearing
• Rotating shield - a conical-shaped, ductile iron, black oxide shield resists asphalt erosion and helps protect the inner sealing elements from large aggregate damage
• Self-adjusting washer - a conical shaped mechanical washer located behind the rotating shield supplies the bearing with third contamination barrier
• High temperature seals - the fourth and final barrier consists of a Nomex* felt seal that works to filter out fine and super fine particles
• Factory lubrication for each bearing is chosen to best fit the conditions of bearing operation. For example, auger bearings use a high-temperature synthetic grease to combat the asphalt high temperatures.
• Wide outer ring design provides increased grease capacity to lubricate the bearings.
• Anti-rotation - pin & dimple system prevents the bearing OD from creep/rotation due to vibration over time while providing a full ± 2° of static misalignment.
• Direct lube - pin & dimple system provides a direct lubrication path into the bearing, eliminating the need to channel grease around a lubrication groove common on standard mounted ball bearing units.
• Black oxide standard on inner/outer rings and seal components inhibits corrosion.
• Zone hardened inner race provides a fully hardened ball path while leaving the race extensions unhardened, allowing better set screw holding power.
• Length through bore is longer than most competitors for greater shaft stability.
• Land-riding brass retainer has high strength, minimizes friction and provides maximum grease circulation.
• 120° balanced set screw position provides three-point balanced contact that minimizes vibration, reduces noise and improves reliability of the shaft assembly.
• Precision manufactured, diamond faceted set screws improve clamping and resist backing out.
• Solid base, pillow block, cast iron housing provides improved stability and resistance to shock and vibration.
• Permanent metal nameplate allows for easy identification after years of operation.
