A proprietary rubber compound for the Gates Green Stripe engine belt is said to resist hardening and cracking under high operating temperatures, as well as damage from exposure to ozone and coolant.
The new belt design also incorporates built-in fibers to improve stability and reduce belt turnover, according to Gates Corp. An underside notch pattern is intended to further increase life by reducing bend stresses on drives with small pulleys and short spans.
The manufacturer says that in field tests the new Green Stripe belts were removed after 250,000 mi. showing only minimal signs of wear.
