Q&A Can Composites Replace Bronze Plain Bearings?
If you’re a regular reader of Tech Talk, it will be no surprise that we’re big fans of composite...
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.
Accommodates incredible compression loads that literally crush competing composite materials.
Reduces wear and extends operating life. Coefficients as low as 0.05 in dry applications and <0.009 in lubricated environments.
Stable in water and corrosive liquids. Absorption rates are negligible, providing near-zero swell.
Suitable for press fit, freeze fit, epoxy bonding, as well as conventional mechanical retention.
Drop in replacement for metal or bronze bearings
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.
Operates flawlessly in temperatures ranging from cryogenic levels to a high of 300°F (149°C). (Call for higher temperature availability).
Compatible with a wide range of lubricants and media
Accommodates high-load with a compact strength to weight ratio
Standard sizes available; an ideal drop-in brass replacement option.
