Urethane is the Best Choice for Timing Belts

Urethane's advantages include:
  • High abrasion resistance (see Comparative Abrasion Resistance Chart). Under Certain conditions - e.g. if a lubricant is used, Gates Mectrol's urethane timing belts may have a longer service life than high-grade steel.   
  • Flexibility over a high range of temperatures: -40°C to 80°C(175°F) with short term to 120°C (250°F)   
  • High elasticity - absorbs shock, impact and vibration   
  • Excellent resistance to oils, greases and some solvents
    Chemical resistance is extremely application specific (temperature, duration, concentration)
    Since Gates Mectrol cannot control the environment under which a belt will be used, we cannot guarantee performance. We will conduct accelerated aging tests at a marketing manager's discretion, but the ultimate decision will be the customer's.
