NT Composite Sleeve Bearings



4 Bolt flange Carbon Sleeve Bearing 4 Bolt Nitronic 50 Flange 4 Bolt flange Carbon Sleeve Bearing

Proven, simple, and reliable bearing that reduces torque by up to 100x and has up to 10x more wear life compared to a carbon sleeve bearing. They run silently, fully self-lubricate, dampen vibration, are corrosion proof, and maintenance free. Ideal for use in hot, extreme cold, and corrosive applications under 100 RPM.



Housing and Retainer Ring Options:


Standard: Enamel painted cast 35 ksi grey cast iron housing with corrosion resistant nickel plated self-aligning steel retaining ring.


Corrosive Service: Cast 304 stainless steel housing and self-aligning retaining ring. 304 stainless steel is widely accepted as an excellent material for use in food service or wet applications.


Fully split: Enamel painted cast split 65-45-12 ductile iron housing with split corrosion resistant nickel plated self-aligning steel retaining ring.

NT 600 Material Benefits

NT600 PTFE composite is chemically inert and will never bond with rust or scale. 10x greater wear life than carbon and eliminates the risk of shaft seizure. Excellent for applications such as dampers, actuators, marine environment, chemical stirring tanks, washdown equipment, and rolling stock conveyors.


  • Continuous service from -400° F to 500° F.
  • Very low coefficient of friction on steel shafting (f=0.03 to 0.003) versus carbon-graphite (f=0.2), allowing for smaller drive motors on conveyors
  • Excellent resistance to shock loads and torsion, will not fracture when stressed
  • Excellent resistance to all types of chemical and environmental corrosion, will not chemically react with shafting
  • Very low wear coefficient versus all sleeve bearing materials, 10x greater life than carbon-graphite
  • Eliminates the risk of seizing due to contaminate build up between the shaft and bearing surface
  • Maintenance free, self lubricating design, not affected by water washout
  • Quiet running
  • Electrically non-conductive
  • Composited PTFE polymer engineered to resist creep at all temperatures
  • Stock bearings available for immediate shipping
