Great for low maintenance projects

Bought these for a custom automotive suspension project. The self-lubricating feature works exactly as described. Very quiet operation even under load.

Excellent wear resistance

We use these in our conveyor systems. They have lasted three times longer than the standard brass bushings we used previously. Highly recommend for high-cycle applications.

Perfect fit for hydraulic repair

Ordered the 15mm inner diameter bushing for a hydraulic cylinder repair. The tolerance was spot on, and installation was smooth. No grease needed which is a huge plus for cleanliness.

Good quality, fast shipping

The material feels robust and the bronze backing provides good structural integrity. Took off one star because the packaging was slightly damaged, but the product itself was fine.

Solid industrial component

Does exactly what it says on the tin. The 14mm size fit my shaft perfectly. Just ensure you ream to the correct size if your housing is tight.

5 FAQ

Q: Are these compatible with stainless steel shafts?

A: Absolutely. The PTFE sliding layer is designed to work efficiently against hardened steel, stainless steel, and chrome-plated shafts.

Q: What is the lead time for bulk orders of the 16mm ID size?

A: For orders over 500 units, please contact our sales team directly. Standard stock usually ships within 2 business days for smaller quantities.

Q: Can these bushings be used in submerged water applications?

A: Yes, the SF-1 composite material is resistant to water and can operate in submerged conditions, though extreme chemical exposure should be avoided.

Q: Is the outer diameter precise enough for press-fit installations?

A: Yes, the outer diameter is manufactured to H7 tolerance standards, making them suitable for standard press-fit housing installations.

Q: Do I need to apply any grease during installation?

A: No, these are self-lubricating. Applying external grease is not necessary and may attract dust in certain environments, though a light film won't damage the PTFE layer.
