Good quality metal
Solid construction and accurate dimensions. The fit was slightly tight initially but seated well after installation. Good value for the price.

No maintenance needed
Installed these on my farm equipment linkage. It has been months and no greasing required. The graphite plugs work exactly as described.

Withstands heat well
Used in a high-temperature environment near an engine block. No signs of wear or degradation after several weeks of operation. Very durable.

Perfect for hydraulic ram repair
These bearings fit perfectly in my hydraulic cylinder setup. The self-lubricating feature saves me time on maintenance. Highly recommend for industrial use.

Accurate dimensions
Measured the inner and outer diameters with calipers and they matched the specs perfectly. Shipping was fast and packaging protected the items well.
Q: What is the recommended shaft tolerance for installation?
A: We recommend a standard h9 shaft tolerance for optimal fit and performance with these copper sleeve bearings.
Q: Can these be used in underwater or wet environments?
A: Yes, the copper alloy material offers good corrosion resistance, making them suitable for wet or mildly corrosive environments.
Q: Is a press-fit installation required?
A: Yes, a standard interference fit is recommended to ensure the bearing remains secure during operation without rotating in the housing.
Q: Which model number fits a 25mm shaft?
A: Models 253225 and 253230 are designed for a 25mm inner diameter shaft. Please check the length requirement to choose between them.
Q: Do these bearings require regular greasing?
