Performance tapered roller bearings - interchangeable with competitive Type E mounting dimensions
Features & Benefits
- Sealmaster® SPB series heavy duty tapered roller bearings with cast steel housing, designed for radial, thrust and combination loading are available with a wide variety of features:
- Inch and metric bore size from 1 3/16" – 5” bore and 40 to 125 mm
- 2 and 4 bolt pillow block
- Multiple sealing options
- Unitized, replaceable cartridge insert allowing +/- 3° static misalignment capability has factory controlled clearances and is factory lubricated.
- Rugged, cast steel split housings meeting SAE J43T specifications 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 contaminant 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).
