Quiet operation
Replaced an old metal bushing with this composite one. The noise reduction in the machinery is noticeable.

Perfect for hydraulic repair
Used this to rebuild a hydraulic cylinder on my excavator. Fit was precise and it slides smoothly without additional grease.

Good quality, tight fit
The bearing quality is excellent. Had to do a slight ream to get it onto the shaft, but once installed it works great.

Solid value
Does exactly what it says. Packaging was a bit minimal but the product itself is wear-resistant and durable.
Q: What is the lead time for bulk orders?

Q: Can this be used outdoors in rain?
A: Yes, the bronze and steel backing offer good corrosion resistance for outdoor use.
Q: Is the 90mm ID exact or nominal?
A: It is nominal. Please refer to the ISO 3547 standard tolerance chart for specific measurements.
