Durable and long-lasting
I've been using these in my workshop for various projects. They hold up well under moderate load and speed. Highly recommend.

Great for hobby projects
Exactly what I needed for my RC car upgrades. The sizing chart was accurate and shipping was fast. Will buy again.

Perfect for motor repair
Used these to fix an old fan motor. The fit was precise and the self-lubricating feature works great. No noise after installation.

Good quality, slight odor
The bushings are well-made and durable. There was a slight oil smell upon opening, but that is expected for this type. Works as described.

Good value for money
Solid product at a reasonable price. Installation required a gentle press fit. No issues so far after a week of use.
Q: What is the outer diameter tolerance?
A: The standard outer diameter tolerance follows ISO H7 specifications for press-fit installations.
Q: Can these bushings be cut to custom lengths?
A: Yes, they can be cut using a fine-tooth saw, but please ensure the edges are deburred after cutting.
Q: Do I need to add additional oil during installation?
A: No, these are oil-impregnated. However, adding a drop of light machine oil before first use can help initial break-in.
Q: Is there a warranty on these bearings?
A: Yes, all our bearings come with a 30-day manufacturer defect warranty. Please contact support for claims.
Q: Are these suitable for high-speed applications?
A: They are designed for low to moderate speeds. For high-speed applications, please consult our engineering team.
