Description du produit

PU timing belts are manufactured in thermoset polyurethane by a unique moulding process.

The high-grade polyurethane gives superior wear and abrasion resistance.

Several type of cords, helicoidally rolled up inside the belts, assure excellent dimensional stability and offer high performances in terms of flexibility and traction resistance

PU timing belts are particularly suitable for power transmission applications.
