Smooth operation
Very smooth sliding motion right out of the box. The flange helps with alignment significantly.

Perfect for linear actuators
Used these for a custom CNC build. The self-lubricating feature saves maintenance time. Fit was precise within tolerance.

Reliable supplier
Ordered bulk quantities. Consistency across the batch was good. One unit had a minor burr on the flange edge but easily filed down.

Good quality, slight delay
Material feels robust. Bronze layer is consistent. Shipping took 3 days instead of 1, but product is solid.

Excellent replacement bushings
Replaced worn-out metal bushings in our conveyor system. No more grease guns needed. Highly recommend for high-cycle apps.
Q: Do you offer bulk discounts for 500+ units?
A: Yes, please contact our sales team via the inquiry form for volume pricing.
Q: What is the hardness of the bronze layer?
A: The bronze layer hardness is typically HB 90-120.
Q: Is this suitable for high-temperature environments?
A: It operates up to 110°C continuously. For higher temps, consider our SF-2 series.
Q: What is the PTFE layer thickness?
A: The PTFE lead layer is approximately 0.03mm to 0.05mm thick.
Q: Can these be pressed into aluminum housings?
A: Yes, but ensure proper interference fit to prevent spinning under load.
