The copper material commonly used for bearings is bronze, such as aluminum bronze, lead bronze, and tin bronze. Common grades include C61400 (QAl9-4), C63000 (QAl10-4-4), C83600, C93200, C93800, C95400, etc.
What are the properties of copper alloy bearings?
1. Excellent wear resistance
Copper alloys (such as bronze and aluminum bronze) have moderate hardness and are not easy to wear under high load and high friction conditions, and can maintain stable performance for a long time.
It has strong embedding properties and can absorb tiny particles from the outside to protect the shaft surface from scratches.
2.Excellent self-lubrication
Some copper alloys (such as lead bronze) have self-lubricating properties, which can reduce friction and avoid sticking or seizure even if the lubricant is insufficient or completely missing.
3. High strength and impact resistance
The copper bearing sleeve can withstand high radial and axial loads, performs well in heavy-load environments, and is suitable for scenes with repeated impact or large vibration.
4. Corrosion resistance
Materials such as bronze and aluminum bronze are corrosion resistant and can adapt to seawater, acid, alkali and other chemical corrosion environments, especially suitable for harsh working conditions.
5. Excellent thermal conductivity
Copper has strong thermal conductivity and can quickly dissipate the heat generated by friction, reducing the impact of high temperature on bearing performance.
6.Quiet operation
Sliding friction makes the copper bearing run more smoothly and with low noise, which is very suitable for equipment with high requirements for quietness.
