Good product, slow shipping
The sleeve itself is excellent quality and the flange edge is well machined. Only downside was the delivery took a bit longer than expected.

Reliable component
Using these in a high-cycle mold application. No signs of wear yet after several thousand cycles. Very satisfied.

High quality steel
Material hardness is consistent. We tested a batch and everything met the HRC standards listed. Great for locating pins.
