Solid industrial component
Does exactly what it says on the tin. Good tolerance on the inner diameter. Would buy again for future maintenance needs.

Perfect fit for my machinery
Ordered the 45mm size and it fit perfectly into our conveyor system. The self-lubricating feature is working great, reducing noise significantly.

Excellent wear resistance
We have been running this bushing in a high-friction environment for three weeks now, and there is no visible wear yet. Highly recommended.

Great for linear motion apps
Used this as a liner for a custom linear bearing project. The oil impregnation really helps keep things moving smoothly without constant greasing.

Good quality copper
The material feels solid and genuine. Installation was straightforward. Only giving 4 stars because shipping took a bit longer than expected.

Reliable and durable
Replaced an old plastic bushing with this copper one. The difference in stability and heat dissipation is night and day.
Q: Does this come pre-oiled or do I need to add oil before installation?
A: These bushings are oil-impregnated during the powder metallurgy process, so they come pre-lubricated and ready for immediate installation.
Q: Is the 50mm size available in bulk quantities?
A: Yes, we offer bulk discounts for orders exceeding 50 units. Please reach out to our sales team via the contact form for a custom quote.
Q: Can this be used in underwater applications?
A: While copper is corrosion-resistant, these self-lubricating bushings are designed for dry or ambient conditions. Continuous submersion may wash out the impregnated oil over time.
Q: What is the outer diameter for the 40mm ID version?
A: The outer diameter varies based on the specific wall thickness required for your application. Please check the detailed dimension chart in the product images or contact us for custom OD specifications.
Q: How does the wear resistance compare to bronze bushings?
A: Our pure copper powder metallurgy sleeves offer excellent conformability and embeddability. While bronze is harder, our self-lubricating copper often provides better performance in low-speed, high-load scenarios without external lubrication.
