P28-8M-20-H high torque drive timing pulleys resemble gears with rounded teeth and engage with a mating toothed belt. They offer an advantage over chain drives by allowing much higher operating speeds, no lubrication and high efficiency. Commonly, the HTD 5M pulleys are used in the areas where access for maintenance is difficult and when systems requirements do not allow slippage. They are straight bored for small sizes and QD Bushed for larger sizes.
