Descriptions

• 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 loadsBack idlers can be used.

Temperature Range

• Range: -54°C to +85°C
