No more oil leaks
Switched from traditional oil bath bushings to these SF-1 composites. Clean operation and no dripping oil underneath the machinery.

Durable under load
Running high speed no issues. We tested them under max dynamic load and they held up perfectly without overheating.

Excellent for automation
Used these on a conveyor system upgrade. The self-lubricating feature saves us so much maintenance time. Fitment was precise.

Good fitment
Quality is good but check tolerance charts before ordering. They are slightly tighter than standard bronze bushings.
