Slightly harder than expected
They work fine but required careful installation to avoid scratching the shaft. Good durability though.

Excellent replacement parts
These copper bushings fit perfectly into my motor assembly. The self-lubricating feature saves me time on maintenance.

Self-lubricating works well
No need for extra grease during installation. They run smoothly and quietly under moderate load.

Good value for money
Quality seems solid for the price. One bushing was slightly tight but worked after gentle reaming.

Fast shipping and safe
Packaging protected the items well. No deformation during transit. Will order again for future projects.
Q: What is the tolerance on the inner diameter?
A: Standard H7 tolerance is applied to ensure a secure fit on most standard shafts.
Q: Can I use these in high heat environments?
A: We recommend operating within -10°C to 80°C. Higher temperatures may degrade the lubricating oil.
Q: Do you offer custom lengths for these bushings?
A: Please contact us for bulk custom orders. Standard sizes are shipped as listed.
Q: Are these suitable for water pump applications?
A: They are best for dry or oily environments. Continuous water exposure may affect the oil impregnation over time.
Q: Is the impregnated oil food safe?
A: No, these are not rated for direct food contact. Please use food-grade specific bearings for such applications.
