Silent operation
Replaced some noisy metal-on-metal contacts in my workshop equipment with these. They run completely silent now. Highly recommend for wear resistance.

Great for low maintenance apps
Using these in an outdoor mechanism where regular lubrication is difficult. The oil-impregnated composite is holding up well against dust and moisture.

Perfect fit for my project
Ordered the 20mm ID version and it fits perfectly into my custom linkage assembly. The self-lubricating feature works great, no need for extra grease.

Good quality, fast shipping
The bearing feels very solid and well-made. Took off one star because the tolerances were slightly tighter than expected, requiring a light ream, but otherwise excellent.

Solid performer
Does exactly what it says on the tin. Good wear resistance and the PTFE layer seems durable. Will buy again for future prototypes.

Excellent value
Very affordable compared to local suppliers. The 22mm/25mm size was hard to find elsewhere, but this arrived quickly and works perfectly.
Q: Is this compatible with food-grade environments?
A: While the materials are robust, this specific SF-1 grade is not certified as food-grade. For food processing machinery, please look for our FDA-compliant specific listings.
Q: Can this bushing be used in high-speed rotating applications?
A: The SF-1 series is primarily designed for low-speed oscillating or sliding movements. For high-speed continuous rotation, we recommend checking our ball bearing series instead.
Q: Do I need to press fit this or can it be glued?
A: These bushings are designed for a press-fit installation into a rigid housing to ensure proper heat dissipation and load support. Adhesives are not recommended as the primary retention method.
Q: What is the exact wall thickness for the 20mm ID / 23mm OD version?
A: For the 20mm ID and 23mm OD variant, the wall thickness is 1.5mm. Please allow a standard machining tolerance of +/- 0.05mm.
Q: What is the maximum static load this can handle before deforming?
A: The maximum static load capacity is rated at 140 N/mm². Exceeding this limit may cause permanent deformation of the PTFE composite layer.
