rubber coated timing belt

Timing belts are typically made of high-quality rubber reinforced with fiber and other materials that allow them to withstand high temperatures and wear. Timing chains, on the other hand, are more robust, making them advantageous for high-performance vehicles that demand durability under extreme conditions. Each system has its own pros and cons. Timing belts are generally quieter and lighter but need regular replacement, typically every 60,000 to 100,000 miles. Timing chains, while more robust and capable of lasting longer, can sometimes generate more noise and require more complex replacement procedures when worn.

A variable belt drive is a mechanical device that transmits power between shafts using a belt and pulley system that can be adjusted to change the tension and/or the diameter of the pulleys. This variability allows for different gear ratios, enabling machines to operate at various speeds and loads. Unlike fixed belt drives, which offer a single gear ratio, variable belt drives provide a more adaptable solution, making them suitable for applications where variable speed and torque are necessary.
