The CJ Composite bearing was the very first filament wound bearing manufactured in the United States nearly 50 years ago. This versatile composite bearing always has - and always will - be USA produced. Most competing products are produced overseas, resulting in inconsistent quality and major delivery issues.
CJ Composite bearings excel where long wear and low maintenance matter most. With a high load capacity and low frictional values, CJ bearings can extend the operating life of your machinery, without the added expense of regular lubrication. They are available in standard and metric sizes, and are an ideal drop-in brass replacement option.
CJ and FCJ Typical Applications
CJ and FCJ Benefits
High-load capacity/high-shock load capability
Accommodates incredible compression loads that literally crush competing composite materials.
CJ composite wound bearings have a unique lubricant embedded within the surface of the liner material which provides maintenance-free operation and eliminates the need for costly and messy greasing systems.
Low coefficient of friction
Reduces wear and extends operating life. Coefficients as low as 0.05 in dry applications and <0.009 in lubricated environments.
Operates flawlessly in temperatures ranging from cryogenic levels to a high of 300°F (149°C). (Call for higher temperature availability).
Dimensionally stable in fluids (water and corrosive liquids)
Absorption rates are negligible, providing near-zero swell
Compatible with a wide range of lubricants and media
Flexible material design
Suitable for press fit, freeze fit, epoxy bonding, as well as conventional mechanical retention.
Low weight/high strength
Accommodates high-load with a compact strength to weight ratio
Drop in replacement for metal or bronze bearings
