Solved my squeaking issue

My excavator had a persistent squeak at the pivot point. Replacing the old bushings with these steel sleeves completely eliminated the noise. Very satisfied.

Excellent wear resistance

We have been using these in a high-friction environment for three months now, and they show minimal signs of wear. Highly recommended for heavy-duty use.

Good value for the price

Solid construction and the copper sleeves seem durable. I deducted one star because the packaging was slightly damaged upon arrival, but the parts inside were fine.

5 FAQ

Q: Are these bushings compatible with the EWR140 model?

A: Yes, these bushings are designed to fit the EWR series, including the EWR140, provided the specific dimensions match your current setup.

Q: What is the hardness rating of the steel used?

A: The steel sleeves are manufactured with a standard industrial hardness suitable for heavy machinery applications, ensuring longevity under stress.

Q: Can these be used in underwater applications?

A: While the steel is treated for corrosion resistance, prolonged submersion may require additional sealing measures. They are primarily designed for standard outdoor construction environments.

Q: Do I need special tools to install these?

A: A standard hydraulic press or a appropriate drift punch and hammer are typically required for press-fit installation. No proprietary tools are needed.

Q: Is grease pre-applied to the copper sleeves?

A: No, the sleeves are shipped dry. We recommend applying a high-quality molybdenum-based grease before installation for optimal performance.
