High-quality synchronous timing belt designed for precise, positive power transmission between toothed pulleys. The H-profile trapezoidal teeth provide accurate synchronization and prevent belt slippage during operation. The 330H size has 66 teeth and a 33-inch pitch length (838.2 mm). A 45 mm width can be supplied as a custom width where required, since standard H belts are commonly offered in widths such as 38.1 mm and 50.8 mm.
