Polyflex JB Belt Gates 7M 1900 - 2 Rib

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.

Construction
-. 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.

Advantages
-. 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 loads.
-. Back idlers can be used.
