Good quality, tight fit

The quality of the bronze is excellent. Just be aware the press fit is quite tight, so ensure you have the right tools for installation. Otherwise, great product.

No oil needed is a game changer

We used these in a conveyor system where oil contamination was a risk. These bronze alloy bushings work smoothly without any additional lubrication.

Withstands high temperatures

Used these in an engine component test bed. They handled the heat well without seizing up. The graphite plugs distribute lubrication evenly.

Perfect for hydraulic cylinders

These bushings fit perfectly into our hydraulic press setup. The self-lubricating feature saves us a lot of maintenance time. Highly recommend for industrial use.

5 FAQ

Q: Can I add oil to these if I want extra lubrication?

A: While they are self-lubricating, adding compatible oil will not damage them, but it is generally not necessary for standard operation.

Q: Are these suitable for underwater applications?

A: Bronze alloy offers good corrosion resistance, but prolonged submerged use may require additional protective coatings depending on water chemistry.

Q: Are these bushings metric or imperial sizing?

A: These MPBZ series bushings are manufactured using metric dimensions (millimeters).

Q: What is the recommended installation method?

A: We recommend a press fit installation. Ensure the housing bore is clean and within the H7 tolerance range.

Q: Do you offer bulk discounts for orders over 100 units?

A: Yes, please contact our sales team directly through the contact page for volume pricing inquiries.
