Perfect fit for my machinery repair

Ordered the 45mm size and it fit perfectly into the housing. The self-lubricating feature is a huge plus as I don't need to worry about greasing it constantly. Very smooth operation.

Great replacement part

Replaced an old oil-impregnated brass bushing with this composite one. It runs quieter and seems to have less friction. Highly recommend for anyone doing equipment maintenance.

Best value for money

Compared to local industrial suppliers, the price here is unbeatable for the quality received. The self-lubricating properties work great in our dusty workshop environment.

Solid performance

Works exactly as described. The 50mm bore was precise. Installation was straightforward. It's been running for two weeks now with no signs of wear.

Excellent for high-load applications

Using these in a conveyor system that runs heavy loads. They handle the stress very well without overheating. The SF1 material is definitely superior to standard plastic bushings.

Good quality, fast shipping

The bearing feels solid and well-made. The bronze layer looks uniform. Took off one star because the packaging was a bit loose, but the product itself arrived undamaged.

5 FAQ

Q: Is the outer diameter standard for a 45mm bore size?

A: Yes, we follow ISO 3547 standards for dimensions. For a 45mm bore, the standard outer diameter is 50mm unless a custom size was specifically ordered.

Q: How does this compare to a traditional bronze bushing?

A: The SF1 composite offers a lower coefficient of friction and better wear resistance in dry conditions compared to traditional bronze, eliminating the need for external grease in many cases.

Q: Does this bearing require any initial lubrication before installation?

A: No, the SF1 composite bearing is self-lubricating due to the PTFE liner and oil-impregnated structure. It is ready to use straight out of the package.

Q: Can I use this in an underwater application?

A: While the material is corrosion-resistant, this specific SF1 grade is designed primarily for dry or intermittently lubricated environments. For continuous submersion, please consult our marine-grade series.

Q: What is the tolerance on the 40mm inner bore?

A: The standard tolerance for the inner bore is H7, which ensures a precise press-fit for most industrial applications.
