Excavator bucket bushing.
1. Mechanical connection and support
Location: Usually installed at the joints of the excavator's boom, dipper, bucket, etc. (such as pins, bucket ears, and horse head parts).
Function: As a sleeve made of metal or composite materials, it fills the gap between the pin and the body to ensure that the parts can rotate flexibly while bearing high-frequency impact and heavy load pressure.
2. Friction reduction and wear resistance
Material properties: It uses high-strength brass, copper alloy or self-lubricating materials inlaid with solid lubricants (such as graphite, MoS₂), with low friction coefficient (μ<0.16) and hardness up to HB210-290, which significantly reduces the direct wear between the pin and the bushing.
Working condition adaptability: It is suitable for oil-free or low-oil environments, and can operate for a long time under harsh conditions such as high temperature (≤300℃), high load (ultimate dynamic load 100N/mm²), dust, mud and water.
3. Extend equipment life
Structural design: By optimizing the material ratio and manufacturing process (such as centrifugal casting and isothermal quenching), a wear-resistant layer is formed on the surface of the bushing, which effectively resists the severe friction and corrosion during excavator operation and extends the replacement cycle (the life of traditional bushings is about 3000-5000 hours, and high-performance products can significantly increase it)
