Gates® 2/7M850JB BL7M850JB/2

Polyflex® JB™ is synonymous with high power density in small spaces. Developed by Gates® and produced to patented manufacturing processes, these belts provide more load-carrying capacity at higher speeds to small multiple V-belt precision 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.

• High modulus polyurethane compound with a high friction coefficient
• The polyurethane compound resists fatigue, wear and ozone
• Excellent adhesion of tensile cords and polyurethane compound leads to high fatigue-resistant and long belt life
• Small cross-section meets special application needs such as high shaft speeds, small drive package size and smooth running requirements
• The 60 deg angle provides more under-cord support to the tensile section and distributes the load more evenly
• Ribs relieve bending stress on small pulleys and provide lateral rigidity
• Long belt life on small pulleys and compact drives
• The precise casting method eliminates overlaps and layers
• High-performance and smooth running for precision applications
• Avoids vibrations when subjected to shock loads
• Joined Belt construction improves stability
• Greater shaft speeds, up to 30,000 rpm
• Cost savings and design freedom
