Special Processing Belts
Description
PU timing belts are suitable for high power and precision motion control, even at high speeds. Our belts perform especially well on light synchronized and stepped drives, in office automation and domestic appliance applications.
Polyester, Kevlar® (Aramid) and steel cord available.
Yellow, grey, red, transparent colors available.
PU Truly Endless timing belts are manufactured by a unique thermoset mouding process. The high-grade polyurethane gives excellent abrasion and shear resistance, combined with a variety of graded steel cords, ensuring high strength and tractive resistance. The result is a timing belt with excellent dimensional stability. H.I.T. Transmission moulded timing belts are manufactured to a tight tolerance range, which assures consiste
