Good performance, tight initial fit

The quality is undeniable and the self-lubricating feature works well. Just note that the initial fit is very tight, so ensure your housing bore is perfectly machined to spec.

Precise dimensions

Ordered a bulk set for our injection molding machines. Every single bushing met the H7 tolerance specs. Fit was perfect right out of the box without needing reaming.

Reduced downtime significantly

Previously we had to stop production every week to lubricate points. These bushings have eliminated that requirement entirely. Great investment for continuous run facilities.

Excellent durability for high-cycle molds

We replaced our standard brass bushings with these graphite-impregnated ones and the difference is night and day. Maintenance intervals have doubled and we haven't seen any galling on the guide pins.
