Reliable component
These shoulder bushings are a staple in our workshop now. The T-flange provides a nice positive stop, and the material hardness prevents deformation even under heavy load.

Perfect fit for our jigs
The tolerance on these bushings is spot on. We use them for high-precision locating pins in our assembly fixtures, and they slide in smoothly without any play. The hardened surface holds up well against repeated insertion.

Good quality steel
Solid construction and the heat treatment seems consistent across the batch we ordered. The only reason for 4 stars instead of 5 is that the lead time was slightly longer than expected, but the product itself is excellent.

Great value for industrial use
Buying these in bulk for our production line. The price point is very competitive compared to other suppliers, and the quality does not seem compromised. Will order again.

Excellent durability
We replaced our old bronze liners with these steel sleeves. They have significantly reduced wear in our high-cycle stamping fixtures. The stepped shaft design makes installation very secure.

Meets spec perfectly
Ordered custom lengths and they arrived exactly to drawing specifications. The ground finish is smooth, reducing friction during operation. Highly recommended for precision machinery applications.
Q: Are these available in metric sizes or only inch?
A: We stock both standard metric and inch sizes. Please check the size selector dropdown or contact us for specific non-standard dimensions.
Q: Can these be used in high-temperature environments?
A: While the steel is heat-treated, these bushings are designed for standard industrial operating temperatures. For extreme heat applications above 200°C, please consult our engineering team for specialized materials.
Q: What is the exact hardness range of the steel used?
A: The bushings are manufactured from high-carbon steel with a surface hardness ranging between HRC 60 and HRC 64 after heat treatment.
Q: Does the package include mounting screws for the flange?
A: No, the package includes only the shoulder bushing unit. Mounting hardware such as screws or bolts must be sourced separately based on your fixture design requirements.
Q: What is the surface roughness (Ra) value?
A: The precision ground surface typically achieves an Ra value of 0.4μm or better, ensuring smooth linear motion and minimal wear on mating pins.
