Excellent fit for small motors
Used these for repairing vintage fans. The oil impregnation works well and reduces friction noticeably.

Good quality bushings
Material feels solid. One size was slightly tight but worked after careful installation.

5 FAQ
Q: Are these resistant to corrosion?
A: The copper base offers good resistance to corrosion in standard indoor environments.
Q: Do I need to add oil before installation?
A: No, these are pre-impregnated with oil and are designed to be self-lubricating during use.
Q: What is the recommended press fit tolerance?
A: We recommend an H7/h6 fit for optimal performance and retention.
Q: Can these handle high RPMs?
A: They are suitable for low to moderate speeds. High-speed applications may require additional lubrication.
Q: Can I cut these to custom lengths?
A: Not recommended, as cutting may affect the oil distribution and structural integrity.
