Good but tight
Quality is good but fit was tight in the housing. Had to press it in carefully. Once installed, performance is solid.

No more grease
Love the self-lubricating feature. It keeps our equipment cleaner and reduces maintenance downtime significantly.

Great for high load
We supply these to local factories. The load capacity holds up well under stress and eliminates the need for regular greasing schedules.

Excellent fitment
Used the 60mm size for a pivot arm on our packaging machine. The tolerance was spot on and installation was straightforward. No squeaking after weeks of operation.
Q: What housing tolerance do you recommend for the 70mm size?
A: We recommend an H7 housing tolerance for optimal fit and performance with this bearing.
Q: What is the typical lead time for the 75mm variant?
A: Most sizes including the 75mm variant are in stock and ship within 2 business days.
Q: Can I cut this bushing to a custom length?
A: Yes, the material can be machined or cut to specific lengths using standard workshop tools.
Q: Is this suitable for submerged underwater applications?
A: While resistant to moisture, prolonged submerged use is not recommended as it may affect the composite liner over time.
Q: Does this bushing require additional grease during installation?
A: No, the SF-1 series is self-lubricating due to the PTFE liner. No additional grease is required.
