Bronze Slippers

Maximum Weight per Piece 5 tons
Bronze slippers are widely used in machinery where parts need to move smoothly while carrying heavy loads. They’re usually made from copper alloys such as bronze or brass, materials known for their durability and stable sliding performance. Each slipper is cast using the centrifugal method, giving it a dense structure that resists friction and prevents surface sticking during operation. In some cases, graphite or other solid lubricants can be added to the surface to improve lubrication and extend service life, especially in equipment that runs under high pressure or limited maintenance conditions.
- Bronze alloys have self-lubricating properties that helps parts move smoothly even under high speed or heavy load.
- Their good thermal conductivity spreads heat evenly, preventing parts from overheating during continuous operation.
- Alloys like aluminum bronze stay stable in humid or chemical environments, keeping performance consistent over time.
Bronze slippers are mainly made from copper alloys with added elements such as tin, aluminum, or iron to improve strength and performance.
- Tin bronze (e.g., ZCuSn10Pb1) provides excellent wear resistance and performs well under heavy loads and low-speed conditions, such as in machine tool guideways.
- Aluminum bronze (e.g., ZCuAl10Fe3) offers higher strength and superior corrosion resistance, making it suitable for marine or chemical equipment.
Two of the most used alloys are C95800 and C90710, each suitable for different operating conditions.
