Specializing in Conveyor Belts & Timing Belts to Help Keep Your Production Running Smooth.
 |
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 represent a modern and efficient of power transmission. They are used of belt teeth gear in mesh to transmit the drving force. PU timing belts are particularly suitable for power transmission applications.
