Features & Benefits
- Super II Construction: Built with an advanced wrapped design that delivers greater strength, minimal stretch, and high-modulus polyester cords to absorb heavy shock loads.
- Raw-Edge Sidewalls: Engineered with specialized raw-edge sidewalls underneath the wrap to optimize pulley grip, reducing energy-wasting slippage, operational noise, and drive vibration.
- High Tolerance Matching: Features tight tolerance matching (such as Timken's Chekmate system) ensuring that multiple belts share equal load distribution when run in multi-groove configurations.
- Extreme Temperature Resilience: Formulated to withstand demanding environments, operating efficiently across a temperature range of -50°F to 250°F while resisting oil, heat, and ozone degradation.
