Excellent corrosion resistance
These copper alloy sleeves hold up incredibly well against constant water exposure and cleaning chemicals. No signs of rust or degradation after three months of heavy use in our detailing shop.

Great value for industrial parts
Bought a mix of sizes for our fleet maintenance. The price point is excellent for this quality of copper alloy. They have solved the squeaking issues on several of our older units.

Good quality, precise fit
Ordered the 15mm bushings for a custom pivot point on a wash arm. The tolerance is tight and the fit was perfect right out of the box. Took off one star because shipping took a bit longer than expected.

Smooth operation immediately
The self-lubricating feature works as advertised. The movement is smooth from the first installation without any break-in period required. Highly recommend for any rotating machinery in wet environments.

Perfect for high-pressure pump repair
I used the 20mm size to repair my commercial car washer pump. The graphite inserts work great, and there is no need for additional oiling which could contaminate the water supply. Very durable.

Solid construction
Very solid brass-like feel. I used the 25mm variant for a heavy-duty linkage. It handles the load well without deformation. Just ensure you measure your shaft diameter accurately before ordering.
Q: Are these bushings suitable for continuous submersion in water?
A: Yes, the copper alloy material and graphite lubrication are designed to perform effectively in wet environments and can withstand continuous water exposure typical in car wash applications.
Q: Is the 30mm size available in stock?
A: Yes, all sizes listed in the MPBZ13 series, including the 30mm inner diameter option, are currently in stock and ready for immediate shipment.
Q: Can these be pressed into a steel housing?
A: Yes, they are designed to be press-fitted into standard steel housings. We recommend using a light interference fit according to standard engineering tables for bushing installation.
Q: Do I need to apply grease or oil during installation?
A: No, these are oil-free bushings with embedded graphite plugs that provide self-lubrication. Adding external grease is not necessary and may attract dirt in some applications.
Q: What is the hardness rating of the copper alloy used?
A: The MPBZ13 series typically features a hardness range of HB 90-120, providing a good balance between wear resistance and conformability for shaft protection.
