Perfect fit for my lathe project

The dimensions were exact as described. The oil-impregnated feature works great, no need for constant greasing. Highly recommended for hobbyist machinery.

Standard industrial grade

This is a standard 3032 sintered bronze bearing. Works exactly as expected for low-speed, high-load applications. Fast shipping too.

Excellent wear resistance

I replaced a plastic bushing with this copper sleeve in a high-friction area. It has been running smoothly for three months with no signs of wear.

Great for heat resistance

Used this in a motor housing that gets quite warm. The heat resistance is impressive, and the self-lubricating feature prevents seizing.

Good quality, slightly tight fit

Quality seems solid. It was a bit tight going onto the shaft initially, but after running it for an hour, it seated perfectly. Good value for the price.

Works but arrived oily

The part functions well, but it arrived very oily due to the impregnation process. Make sure to have rags ready when unpacking. Otherwise, it does the job.

5 FAQ

Q: What is the actual length of this bushing?

A: The standard length for the 3032 model is typically 25mm, but please verify the specific listing details as lengths can vary by manufacturer.

Q: Is this suitable for high-speed motors over 3000 RPM?

A: Self-lubricating sintered bronze bearings are generally best suited for low to medium speeds. For high-speed applications, we recommend ball bearings or forced lubrication systems.

Q: Do I need to add extra oil before installation?

A: No, the bearing is pre-impregnated with oil. However, adding a drop of light machine oil on the shaft before installation can help during the initial break-in period.

Q: Can this be used in underwater applications?

A: While copper bronze has good corrosion resistance, this specific oil-impregnated bearing is designed for dry or ambient conditions. Continuous submersion may wash out the lubricant.

Q: What is the tolerance on the inner diameter?

A: The typical tolerance for these powder metallurgy parts is H7/H8, but for precision fits, we suggest measuring your specific unit upon arrival.
