Split Sleeve Bearings



HTB split carbon pillow block Bolted HTB split steel backed carbon bearing HTB split steel backed carbon bearing HTB split carbon pillow block

Built for toughness and durability, High Temp Bearings Inc. precision split, self-aligning sleeve bearings for radial load applications. Stock flanges made from high strength ductile iron with a sturdy doweled and bolted closure. Available for interchange with all common cast 2-bolt, 4-bolt and pillow block flanges for bearing bores up to 4 ½ inches.


Split Bearings


  • Fully Split, corrosion resistant, nickel plated alloy steel retainer, with HT750, HT1000, NT600 or BR500 bearing liner. Split, enamel painted, ASTM 65-45-12 ductile iron flange, bolted and doweled closure with H7 tolerance spherical self-aligning bearing seat.

  • Ductile iron naturally weathers and forms a stable oxide layer providing long lasting durability outdoors in industrial and marine environments. Maximum service temperature up to 1100°F.

  • Accepts heavy radial loads at moderate speed, tolerates moderate vibration and light axial loads applied to the bearing face. Flanges interchangeable with standard HTB mounted flanges and many other popular brands.


HTB Split steel backed sleeve bearing

HT750, HT1000 carbon and NT600 materials are engineered to resist the adhesion of rust and scale, significantly reducing the risk of bearing seizure on infrequent use applications such as dampers and actuators located outdoors. NT600 material is chemically inert and non-galvanic to all shaft materials.


HTB Sleeve Bearing Temperature Range
HT750 Carbon-Graphite:

For a broad range of service requirements including high to low temperature and wet applications requiring precise mechanical positioning. Rated for continuous service from -40°F to 750°F. Self-lubricating, maintenance free.

HT1000 Carbon-Graphite:

For very hot or cold applications from -200°F to 1000°F requiring precise mechanical positioning. Not for use between -40°F and 250°F. HT1000 is for extreme temperatures only. Self-lubricating, maintenance free.

NT600 PTFE Composite:

For elevated, low temperature and corrosive applications from -400°F to 500°F. Reduces motor torque and rolling resistance by 10x to 100x vs. an equivalent carbon sleeve. Excellent for conveyor systems, noise control, resistance to shock loads and exceptionally long wear life. Self-lubricating, maintenance free.
