Solid performance in dusty environments
Our facility has a lot of particulate matter. These bushings handle the dust well without grinding down like our previous units. Deducting one star only because shipping took longer than anticipated.

Reliable industrial grade component
Bought the 65mm set for a custom pivot assembly. The steel backing provides great structural integrity while the sliding surface is incredibly smooth. Highly recommend for heavy machinery.

Cost-effective maintenance solution
Eliminating the need for regular greasing has saved our team significant maintenance hours. The initial cost is higher than plain bronze, but the reduced downtime makes it worth every penny.

Excellent for high-cycle applications
Using these in a conveyor system that runs 24/7. The self-lubricating layer is wearing evenly, and we haven't had a single seizure or sticking incident since switching from standard bronze bushings.

Good durability, precise sizing
Ordered the 50mm ID size. The tolerance was spot on, making installation straightforward. They run slightly warmer than expected during the break-in period, but performance stabilized quickly.

Perfect replacement for our furnace rollers
We replaced the old lubricated bushings in our heat treatment line with these SF-1 composites. The oil-free feature keeps our workspace much cleaner, and they have held up perfectly under continuous operation for three months.
Q: Are these suitable for underwater applications?
A: While the material is corrosion-resistant, the SF-1 series is optimized for dry or intermittent wet conditions. For continuous submersion, we recommend our stainless steel backed variants with specific sealing.
Q: How do I determine the correct housing fit tolerance?
A: For standard applications, we recommend an H7 housing tolerance. Please refer to the technical datasheet included in the product download section for detailed interference fit charts based on your specific diameter.
Q: What is the lead time for the 80mm inner diameter size?
A: The 80mm ID size is currently in stock and ships within 2 business days. Custom lengths for this diameter may require an additional 5-7 days for processing.
Q: Can these bushings be used in temperatures above 150°C?
A: No, the standard SF-1 composite is rated for a maximum continuous operating temperature of 110°C. For higher temperatures, please consult our catalog for high-temperature graphite alternatives.
Q: Do I need to apply any grease during installation?
A: No additional lubrication is required during installation or operation. The PTFE layer is designed to transfer to the mating shaft to create a low-friction surface immediately upon movement.
