Good Quality
Slightly tight fit but once installed they work smoothly. Good value for the price compared to local hardware stores.

Smooth Operation
No noise after installation. The oil impregnation really works well for reducing friction in my fan motor.

Perfect Replacement
Fit my motor perfectly. The self-lubricating feature saves a lot of maintenance time. Highly recommend for DIY repairs.
Q: Do I need to add oil to these bearings before installation?
A: No, these are oil-impregnated during manufacturing. They are self-lubricating and do not require additional oil.
Q: What is the recommended method for installing these sleeves?
A: A standard press fit into the housing is recommended. Ensure the housing bore is clean and free of burrs before installation.
Q: What is the inner diameter tolerance for these bushings?
A: These bushings are manufactured with standard H7 tolerance suitable for most general mechanical applications.
Q: Can I use these bushings in outdoor wet environments?
A: While copper is resistant, we do not recommend submerged use. They are best suited for dry or mildly humid indoor conditions.
Q: Are these made of solid copper or a composite?
A: They are made using powder metallurgy techniques with copper base, which allows for oil impregnation within the material structure.
