Features and Benefits

Excellent adhesion of tensile cords and polyurethane compound leads to high fatigue resistance 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° angle provides more undercord 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.
