Great value
Works as described for my automotive project. Shipping was fast. Would have given 5 stars but the packaging was a bit minimal, though the parts were undamaged.

No grease needed
Saved time on maintenance since these are self-lubricating. The bronze composite layer seems durable. Great value for the price compared to local suppliers.

Perfect for hydraulic repair
Used these on a cylinder rebuild for my excavator. The fit was precise and no grease needed during installation. Very satisfied with the wear resistance so far.

Good quality, tight fit
Material feels solid and well-made. Had to use a press to get them in, which is expected for this type of bushing. One star off because sizing chart could be clearer.

Excellent wear resistance
Running in a high load application on a conveyor system. They have been operating smoothly for three months without any maintenance. Highly recommend for industrial use.
Q: Do these require grease during installation or operation?
A: No, the SF-1 bushings are self-lubricating due to the PTFE layer. No additional grease is required for standard operation.
Q: What tolerance should I use for the housing bore?
A: We recommend an H7 tolerance for the housing bore and a g6 tolerance for the shaft to ensure optimal performance.
Q: How should I install these sleeves?
A: These are designed for a press fit installation. Please ensure the housing is clean and chamfered to avoid damaging the lining during insertion.
Q: Can this bushing handle water exposure?
A: Yes, the composite material is resistant to water and can be used in wet environments without rusting significantly.
Q: What is the maximum continuous temperature?
A: The maximum continuous operating temperature is +110°C. Short-term peaks up to +130°C are acceptable but may reduce service life.
