Great value bulk pack

Bought a variety pack to keep in the workshop. Dimensions are consistent across the different sizes. Very happy with the purchase price.

Okay for light duty

Works fine for my hobby project but I wouldn't recommend it for heavy industrial loads. The flange is a bit thinner than expected on the smaller sizes.

Perfect for motor repairs

Used these to replace worn bushings in a small electric motor. The stepped shoulder design made installation straightforward and the fit was precise. No noise after running for a week.

Excellent durability

I have used these in a high-cycle linkage mechanism. They hold up well under moderate load and the self-lubricating feature saves maintenance time.

Good quality, tight fit

The material quality seems excellent. Just be aware that the inner diameter is quite tight initially. You may need to ream it slightly for your specific shaft tolerance.

5 FAQ

Q: Can these be used in wet environments?

A: While copper bronze resists corrosion, these are not designed for continuous submersion in water. Use in dry or lightly damp conditions.

Q: Is the flange thickness standard across all sizes?

A: No, the flange thickness varies proportionally with the inner and outer diameter specifications. Please check the detailed dimension sheet.

Q: Do I need to add oil before installation?

A: No, these bearings are pre-impregnated with oil. Adding external oil is not necessary for standard operation.

Q: What is the maximum rotational speed?

A: Maximum speed depends on load and lubrication, but generally should not exceed 2000 RPM for continuous use.

Q: What shaft tolerance is recommended?

A: We recommend a shaft tolerance of h7 or g6 for optimal performance and fitment.
