PU Timing Belts is manufactured by a unique thermoset moulding process. The high-grade polyurethane gives excellent abrasion and shear resistance, combined with a variety of graded steel cord, ensuring high strength and tractive resistance. The result is a timing belt with excellent dimensional stability. PU Timing Belts is manufactured to a tight tolerance range, which assures consistent length and thickness. Mechanical features Consistent dimensional stability Low pre-tension Low noise High abrasion resistance Low maintenance High flexibility Linear speeds up to 80M/SEC Chemical features: Ageing, Hydrolysis, UVA rays, Ozone. Working temperature range -30°C to +80°C(up to +110°C for short periods) High resistance to oils, fats and greases Good resistance to most acids and alkalis
