Fast shipping and well packed

Arrived earlier than expected. Each piece was individually wrapped to prevent damage. The 20mm size works great for my project.

Works well for agricultural repair

Replaced old bushings on a tractor linkage. They handle the dust and vibration well. Would buy again when needed.

Good quality, tight tolerance

The bronze quality is excellent. They were a bit tight on installation so I had to hone them slightly, but once in, they run very smooth.

Perfect fit for my lathe

Ordered the 18mm ID bushings and they fit the shaft perfectly. The self-lubricating feature saves me time on maintenance. Highly recommend for light industrial use.

Durable and reliable

Using these in a conveyor system for three months now. No wear visible yet and no squeaking. Great value for the price point.

5 FAQ

Q: Can these withstand temperatures above 100°C?

A: No, the maximum operating temperature is 80°C. Higher temperatures may degrade the oil impregnation.

A: These are sold in packs of 10 pieces per standard package. Custom quantities may be available upon request.

Q: What shaft tolerance do you recommend for the 16mm ID?

A: We recommend a shaft tolerance of h9 for optimal fit and performance with this series.

Q: Do I need to add grease to these bushings during installation?

A: No, these are self-lubricating oil-impregnated bushings. Adding external grease is not required and may clog the pores.

Q: Can I cut these bushings to a custom length?

A: Yes, they can be cut to length. Please ensure you deburr the edges after cutting to prevent shaft damage.
