Good but tight fit

Quality is good but the bearing fit was slightly tight on my specific model. Worked it in after some use.

Excellent durability

These pulleys have held up well under continuous operation. The stainless steel quality is evident and wire feeding is much smoother now.

Smooth wire feed

Noticed less friction immediately after installation. Great replacement part for older machines.

5 FAQ

Q: Which model fits a 2mm wire diameter?

A: For 2mm wire, we recommend the SZV4-12 or SZU4-12 depending on your groove preference.

Q: Can this handle high-speed feeding?

A: Yes, these pulleys are rated up to 3500 RPM, suitable for most high-speed wire feeding applications.

Q: Is the material magnetic?

A: 304 Stainless Steel is generally non-magnetic or slightly magnetic depending on the manufacturing process.

Q: What is the difference between V and U groove?

A: V-Groove provides better traction for driving wire, while U-Groove is gentler and reduces marking on soft wires.

Q: Is additional lubrication required?

A: The bearings come pre-lubricated and sealed. No additional lubrication is needed for standard use.
