Zinc Alloy Pulleys
Die cast zinc alloy pulleys for cable and rope guidance in light-duty applications. Kailipu offers six lines across fixed and swivel eye single and double pulley designs, all with steel or galvanized eyes and nickel or zinc plated finishes, so a buyer can source a full pulley set for a control system or rigging adjustment without splitting the order across multiple suppliers.

Who It Is For
Buyers Who Specify Zinc Alloy Pulleys
- Industrial equipment builders integrating pulleys into control systems or tensioning mechanisms
- Rigging and lifting service companies needing light-duty pulleys for cable adjustment or alignment
- Marine and offshore maintenance teams using pulleys for guide lines on deck equipment
- Manufacturers of cranes, hoists, or winches requiring low-friction pulleys for rope path management
- Automation and robotics integrators using pulleys in cable-driven positioning systems
Problems Solved
What Zinc Alloy Pulleys Solve on the Job
- A control system or rigging setup needs a pulley for rope guidance but the load is too light for a steel pulley, so a heavy-duty unit is overkill and expensive
- The pulley must swivel to follow cable movement but the only available models are fixed, causing binding or misalignment
- The finish is plain zinc or no coating, so the pulley corrodes quickly in a damp or outdoor environment
- No single supplier carries both single and double wheel pulleys in the same material and finish, forcing multiple purchase orders
- The pulley is rated for lifting but the application is only for adjustment, so the buyer pays for a higher safety factor than needed
- A custom finish or marking is needed for a branded control panel or machine, but the supplier only offers standard options

Applications
Where Zinc Alloy Pulleys Are Used
- Guiding a control cable through a tight space in a crane cab where the cable must pivot freely
- Adjusting the tension on a winch cable using a swivel eye pulley block on a mobile platform
- Routing a wire rope through a fixed pulley in a factory automation system where weight is not a factor
- Mounting a double wheel pulley on a maintenance trolley to guide a cable during equipment servicing
- Using a nylon wheel fixed pulley in a cleanroom environment where metal wear particles are not allowed

Answers
Zinc Alloy Pulleys FAQ
Are these pulleys rated for lifting?
No. These die cast zinc alloy pulleys are designed for cable and rope guidance only, not for lifting. They are not tested or rated for working load limits.
What is the difference between a fixed eye and a swivel eye pulley?
A fixed eye pulley has a non-rotating attachment point, so the pulley stays in one position. A swivel eye pulley rotates to follow the cable path, reducing binding and misalignment.
Can I get a load capacity chart for these pulleys?
Yes. Load capacity varies by size and wheel diameter. Contact us with the model number or drawing to receive the appropriate chart.
What finishes are available on the pulleys?
Standard finishes are nickel plated and zinc plated. Plain finish is available. Custom coatings such as electrophoretic black or powder coating can be arranged.
Do you supply Material Test Certificates?
No. These pulleys are not used in lifting applications and are not subject to material test certification. They are not required to have MTCs.
Can you customise the finish or marking?
Yes. Custom surface finishes including electrophoretic black, powder coating, and zinc plating are available. Custom tonnage stamping and private label marking are also supported.
What is the smallest order you accept?
We accept small orders for mixed configurations. You can order one unit of each type or a combination across the six lines without needing a full container.
