GATES POLYFLEX BELTS

Product Details

Developed by polyflex belts and produced to patented manufacturing processes, Gates Polyflex® JB™ belts provide more load-carrying capacity at higher speeds to small precision multiple V-belt drives. This results in significant cost savings and improved design freedom. Polyflex® JB™ belts are recommended for use on bench-type milling machines, lathe drives, woodworking and metalworking machine spindle drives, computer peripheral equipment, small blowers, etc. They are available in 3M-JB, 5M-JB, 7M-JB, and 11M-JB sections.

POLYFLEX® JB™
Polyurethane multiple V-belt

Construction

· Joined belt construction improves stability.
· Ribs relieve bending stress on small pulleys and provide lateral rigidity.
· 60° angle provides more undercard support to the tensile section and distributes the load more evenly.
· 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 tensile cords and polyurethane compounds leads to high fatigue resistance and long belt life.
· Extra toughness. The polyurethane compound resists fatigue, wear, and ozone.

Advantages

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

Temperature ranges from -54°C up to +85°C
