RS PRO Timing Belt Pulley Cast Iron, 20 mm Belt Width, 8 mm Pitch, 48 Tooth HTD PULLEY 8X20X48

The RS PRO HTD PULLEY 8X20X48 is a heavy-duty timing belt pulley engineered for demanding mechanical power transmission applications. Manufactured from high-quality cast iron, this pulley delivers outstanding rigidity and resistance to wear, making it suitable for extended service in industrial environments.

Featuring 48 precisely cut teeth with an 8 mm pitch, the pulley is optimized for high-torque drive systems and ensures reliable belt engagement, reducing slippage and maintaining timing accuracy throughout operation. The 20 mm acceptable belt width allows compatibility with commonly used HTD timing belts, enabling versatile integration in conveyor systems, automated machinery, and drive assemblies.

The pulley is designed for use with taper bush installations and supports a bore diameter of 50 mm, accommodating standard industrial shafts. With an outside diameter of 120.86 mm, it provides balanced load distribution and smooth rotational performance at moderate operating speeds. Adherence to ISO 4183 requirements guarantees dimensional consistency and interchangeability within standardized setups.

HTD (High Torque Drive) pulleys are widely deployed across manufacturing, material handling, and automation systems where consistent power transmission and synchronization are critical. The RS PRO cast iron variant ensures fatigue resistance and thermal stability for extended operation in harsh industrial environments.

Typical applications include mechanical drive assemblies, conveyor lines, packaging machines, and power transmission units in sectors such as manufacturing, processing, logistics, and robotics. The robust construction and precise engineering ensure compatibility with all manufactured HTD belts and seamless performance in demanding use cases.
