Perfect for motor repair
Fits perfectly in my electric motor housing. Self-lubricating feature works great and reduced noise significantly.

Standard industrial grade
Hardness is consistent across the pack. One was slightly tight but fitable with proper tooling.

Good value bulk pack
Sizes are accurate but shipping took a bit long. Quality is solid for the price point.

Exactly as described
Needed 10mm bushings for a project. These are high quality sintered bronze and machined well.

Great for appliances
Used these to fix a washing machine pump. Running smoothly now without any squeaking.
Q: Can these be machined after purchase?
A: Yes, but please note that re-impregnation may be needed if significant material is removed.
Q: Are these suitable for high-speed applications?
A: They are best suited for low to medium speed loads to ensure longevity.
Q: What is the interference fit recommendation?
A: Typically 0.05mm to 0.10mm interference is recommended for secure housing.
Q: Do I need to add oil before installation?
A: No, these are pre-impregnated with oil during the sintering process.
Q: Is the material corrosion resistant?
A: Bronze offers good resistance but these are not recommended for continuous marine use.
