Zinc Alloy Steel Nickel Plated Pulley Sheave
A small pulley can look like a simple part, but the details still matter.
This pulley uses a zinc alloy steel body and nickel-plated wheel. The wheel is made to run smoothly with rope or cord, and the metal surface is finished to keep the part clean and easy to handle.
There are a few versions to choose from. You can get a single or double wheel, and the top connection can be fixed or swivel.
For most orders, we suggest starting with the rope you are using. The rope diameter, wheel groove and mounting point all need to work together. If this is a replacement part, the old pulley is also useful for comparison.

Fixed Eye or Swivel Eye?
The two versions mainly differ in the way they connect to the mounting point.
Fixed Eye
The eye stays in one position. It is a straightforward option when the pulley is mounted at a fixed point.
Swivel Eye
The eye can turn during use. This gives the pulley more freedom when the rope direction changes.
| Type | Main Difference |
|---|---|
| Fixed Eye | Stays in one position |
| Swivel Eye | Can rotate at the connection |
Single Wheel vs. Double Wheel
Both single and double wheel designs are available.
A single-wheel pulley has one sheave and takes up less space.
A double-wheel version has two sheaves in one body and can be used when two rope paths are needed.
| Version | Structure |
|---|---|
| Single Wheel | 1 sheave |
| Double Wheel | 2 sheaves |
Match the Pulley With the Rope
The rope size is one of the first things to check.
A rope that is too large may not sit correctly in the groove. A rope that is too small may move around too much during use.
Before ordering, check:
Rope diameter
Wheel diameter
Groove size
Eye opening
Overall pulley size
If you already have the old pulley, a photo with the main dimensions can help us identify the closest version.
Nickel-Plated Wheel
The wheel uses a nickel-plated surface. This gives the wheel a clean metal finish and adds surface protection.
The surface should be smooth, especially around the area where the rope runs.
When checking a sample, don't only look at the color of the plating. Turn the wheel by hand and check the groove with your fingers.
There should be no obvious sharp edges or burrs.
What Dimensions Should You Check?
For a replacement pulley, these dimensions are more useful than the product name alone.
| Dimension | Why Check It |
|---|---|
| Wheel Diameter | Determines available wheel size |
| Wheel Width | Must match the rope and housing |
| Groove Size | Needs to suit the rope |
| Eye Opening | Must fit the connector |
| Overall Height | Affects mounting space |
| Overall Width | Important in compact installations |
What to Check When Comparing Samples
A quick sample check can cover the main points:
Wheel: Turn it by hand and check for smooth movement.
Groove: Check for sharp edges or obvious burrs.
Housing: Look for cracks or major casting defects.
Eye: Check that the opening fits your mounting hardware.
Plating: Look for an even surface without obvious peeling.
These are simple checks, but they can catch many problems before a larger order.
FAQ
Q1: What material is the pulley made from?
The pulley uses a zinc alloy steel body with a nickel-plated wheel.
Q2: Is the wheel nickel plated?
Yes. The wheel has a nickel-plated surface.
Q3: Can I choose a single or double wheel?
Yes. Both versions are available.
Q4: What is the difference between fixed and swivel eye?
The fixed eye stays in one position. The swivel eye can rotate at the connection point.
Choose based on how the pulley will be mounted and how the rope moves.
Q5: How do I choose the right pulley size?
Start with the rope diameter and mounting dimensions.
For a replacement, it is best to compare the old pulley size rather than choosing only by appearance.
Q6: Can this pulley be used with different rope sizes?
Different pulley sizes can be matched with different rope diameters. The rope should fit the wheel groove properly.
Please provide the rope diameter when you are not sure which size to choose.
Q7: Can you make custom sizes?
Custom sizes can be discussed according to the drawing, sample or required dimensions.
Q8: Can I order a sample first?
Yes. A sample can be used to check the rope fit, wheel movement, dimensions and surface finish before a larger order.
Q9: What should I provide when asking for a quotation?
The basic information is enough:
Pulley type + single/double wheel + fixed/swivel eye + rope diameter + quantity.
If you have a drawing or old pulley, you can send that as well.
