Features & Benefits

• Sealmaster® RPB-XT series heavy duty tapered roller bearings designed for radial, thrust and combination loading are available with a wide variety of features:
• Inch and metric bore size from 2 1/4" – 5” bore and 60 to 125 mm
• 4 bolt pillow block
• Double lock collar
• Multiple sealing options
• Non-expansion and expansion
• Unitized, replaceable cartridge insert allowing +/- 3° static misalignment capability has factory controlled clearances and is factory lubricated.
• Durable cast iron split housings allow for quick insert replacement when change-out is needed while the housing base remains fixed and aligned with the shaft, reducing downtime and maintenance costs.
• Black oxide standard on outer rings, lock collars and seal components inhibits corrosion.
• Anti-rotation pin prevents the bearing OD from creep/rotation due to vibration over time.
• Direct lube and venting system:
• Provides a direct lubrication path into the bearing.
• Secondary internal relief port prevents seal damage by venting pressure from over greasing.
• Grease fitting position at 30° resulting in less chance of being broken off.
• Race mounted seals are not subject to misalignment distortion and direct contaminants away from the sealing surface available as:
• Standard, felt lined flinger seal, which acts as a filter to help exclude dry, dusty and dirty contaminants.
• Contact seal available for wet, moist conditions (-C).
• Nomex* lined flinger seal for high temperature applications up to 400°F (-N).
• Lock collars with two, diamond faceted, point setscrews at 120° for balanced, three point contact.
• Expansion roller bearing pillow blocks available for use when significant temperature differentials are expected between shafts and mounting structures or shaft is unusually long – specify ERPBXT.
• Permanent metal nameplate allows for easy identification after years of operation.
