KDB 314
Material
Carbon steel +CuSn8Ni1
Application features
Suitable for oil lubrication, lower friction factor
Extremely high fatigue strength and poor lubricity require sufficient lubricating oil to meet the RoHS directive
Oil holes, oil holes or oil tanks can be set
The sliding layer can be refined to improve the matching accuracy
Suitable for high load and medium speed conditions
Used in high-speed internal combustion engine spindle, connecting rod, rocker arm, oil pump, etc.
