Descriptions

This compact and strong belt with nominal top width from 3mm to 11mm transmits more power and allows high speed ratios
Polyflex® is suited for extremely small diameter pulleys and very compact drives with high rotational speeds
Ideal for use on machines and machine tools requiring high performance and smooth operation in limited space such as bench type milling machines, lathe drives, woodworking and metalworking machine spindle drives, computer peripheral equipment, small blowers, etc.

Construction

Polyurethane compound, superior to conventional belt materials, offers high fatigue and wear resistance and high friction coefficient
It also improves adhesion to the polyester tensile cords
Polyurethane is extremely resistant to heat, chemicals and oil
Uniformity throughout Polyflex® is ensured because the polyurethane compound is not layered but cast as a single unit after the positioning of the polyester tensile cords in the mold
Ribbed top provides lateral rigidity without increasing bending stresses
The ribs also help to keep Polyflex® belts running cool
60º angle results in better support of the tensile section and provides a more even load distribution

Advantages

Design freedom and space savings which are not possible with conventional rubber construction belts
Extremely smooth and cool running
Low maintenance cost as belt needs less retensioning
Long belt life on compact drives
Back idlers can be used
Smaller drive package
