CJ | Composite Wound Self-Lubricating Bearings

CJ | Composite Wound Self-Lubricated Bearings

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

  • Agriculture (e.g., earth moving equipment)
  • Automotive
  • Construction
  • Marine
  • Railroad
  • Material Handling Equipment

CJ and FCJ Benefits


  • Self-lubricating design

    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.

  • Temperature resistant

    Operates flawlessly in temperatures ranging from cryogenic levels to a high of 300°F (149°C). (Call for higher temperature availability).

  • Chemical resistant

    Compatible with a wide range of lubricants and media

  • Low weight/high strength

    Accommodates high-load with a compact strength to weight ratio

  • Available in Imperial and Metric Sizes

    Standard sizes available; an ideal drop-in brass replacement option.
