Standard replacement part
Ordered these as replacements for worn-out guides. They fit perfectly into the existing bores without modification.

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.

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