Gates Polyflex JB Joined V Belt

  • Polyflex® JB® is synonymous with high power density in small spaces. Developed by Gates and produced to patented manufacturing processes, Polyflex® JB® belts provide more load-carrying capacity at higher speeds than small precision multiple V-belt drives. This results in significant cost savings and improved design freedom
  • Recommended for use on bench type milling machines, lathe drives, woodworking and metalworking machine spindle drives, computer peripheral equipment, small blowers, etc


  • Joined belt construction improves stability
  • Ribs relieve bending stress on small pulleys and provide lateral rigidity
  • 60º angle results in better support of the tensile section, and provides a more even load distribution
  • Small cross-section meets special application needs such as high shaft speeds, small drive package size and smooth-running requirements
  • High modulus polyurethane compound with a high friction coefficient
  • The precise casting method eliminates overlaps and layers
  • Excellent adhesion of polyester tensile cords and polyurethane compound leads to high fatigue resistance and long belt life
  • Extra tough, the polyurethane compound resists fatigue, wear and ozone.


  • Long belt life on small pulleys and compact drives
  • Greater shaft speeds, up to 30,000rpm
  • High performance and smooth running for precision applications
  • Cost savings and design freedom
  • Avoids vibrations when subjected to shock loadsBack idlers can be used.
