Our core services include castings (free tolerance: ±1mm), CNC machining services (precision turning and milling with an accuracy of ±0.005mm), precision gear skiving (gear module 0.1-5.0, tooth top diameter 3mm-300mm), and a variety of industrial control spare parts. In the precision transmission sector, we offer rotary index tables, hollow rotary actuators, planetary gearboxes, harmonic drives, and other products. Furthermore, to meet customers' specific equipment needs, we also provide consumables such as synchronous pulleys.
Products Description
Hansheng Automation focusses on the research, development, and production of heavy-duty pulleys, pulley systems, and pulley blocks. They use CNC precision machining technology to offer complete solutions for industrial heavy-duty uses, from single pulleys to multi-pulley systems. We have three categories of specialised products: CNC pulleys, taper bushing keyless timing pulleys, and more.These are particularly suitable for applications such as lifting heavy objects and marine engineering in extreme load environments.
Core Product Types and Technical Advantages
Taper Bushing Keyless Timing Pulley
The keyless design achieves gap-free transmission through axial locking of the tapered bushing, suitable for heavy-duty pulleys in mining crushers and other applications with frequent start-stop cycles, improving installation efficiency by 50%.
Tensioning Sleeve Keyless Synchronous Pulley
The radial expansion fixation structure can withstand 30% higher torque, commonly used in hydraulic systems of construction machinery as a core transmission component of heavy-duty pulley systems.
High-torque synchronous pulley with shoulder design
The dual-side shoulder design controls belt offset within ±0.1mm, suitable for high-precision applications such as aircraft engines, representing an upgraded solution for high-torque heavy-duty pulleys.
Advantages of CNC Machining for Heavy Duty Pulleys
Heavy-duty pulleys utilize five-axis CNC machining (pulley CNC) to achieve:
Tooth profile accuracy of ±0.05mm (laser-cut GT/HTD/MXL tooth profiles).
Surface roughness Ra ≤ 1.6μm (30% better than traditional casting processes).
CNC pulley customization capabilities: supports non-standard bore diameters (Φ10–Φ100mm) and special flange designs.

Multi-scenario applications
Port crane applications
Equipped with heavy-duty pulley blocks and rope pulleys, providing 20-ton-class stable lifting capacity for shore-based container cranes, meeting safety standards for lifting heavy objects.
Marine Engineering Applications
316L stainless steel heavy-duty pulleys with Teflon coating, offering 8-10 years of maintenance-free operation in seawater environments, suitable for rope pulley requirements in ship winches.
CNC Machining Situation
High-precision CNC pulleys are built into machine tool drive systems. They have a tooth profile inaccuracy of less than 0.03 mm, which makes sure that there is no slip synchronisation during multi-axis simultaneous cutting.
Hansheng Automation leverages years of CNC precision machining expertise to provide comprehensive solutions for your heavy-duty equipment, from heavy-duty pulleys to pulley systems.
