Excellent for high-load applications
Using these on a heavy-duty agricultural chain setup. They handle the dust and load much better than standard bronze bushings. The oil-impregnated composite really makes a difference in longevity.

Perfect fit for our conveyor chain
We replaced several worn-out bushings in our packaging line with these SF1 units. The self-lubricating feature has significantly reduced downtime for greasing. Installation was straightforward, and the fit is precise.

Good durability, slightly tight fit initially
The quality of the copper sleeve is evident. It felt a bit tight when pressing it into the housing at first, but once seated, it operates smoothly. No noise after two weeks of continuous run.

Reliable performance
Solid product. The 25mm option fit our specs perfectly. I deducted one star only because shipping took a day longer than expected, but the product itself is top-notch.

No more squeaking!
Our old chain system was incredibly noisy. After swapping in these composite bushings, the operation is whisper quiet. Highly recommend for anyone dealing with noisy machinery.

Cost-effective solution
Bought these to maintain our fleet of delivery vehicles. The price point is great considering the maintenance savings. We haven't had a single failure since switching to this model.
Q: Can this bushing be used in wet environments?
A: Yes, the composite material and copper sleeve offer excellent corrosion resistance, making it suitable for damp or wet industrial environments.
Q: Do I need to apply additional grease during installation?
A: No, the SF1-252825 is self-lubricating and oil-impregnated. Adding external grease is not necessary and may attract debris in some applications.
Q: What is the tolerance range for the 25mm inner diameter?
A: The inner diameter follows standard H7 tolerance specifications to ensure a precise fit with your shaft or pin.
Q: How long is the warranty on these bushings?
A: We provide a standard 1-year warranty against manufacturing defects. Please contact us with your order number if you experience any issues.
Q: Is this compatible with stainless steel chains?
A: Absolutely. The composite material is non-galling and works very well with stainless steel pins and links, reducing wear on both components.
