KDB 203
Material
Mild steel + porous sintered copper + POM/filler (blue)
Application features
Grease lubrication working conditions, low friction factor and wear rate
The sliding layer can be set with oil holes or oil tanks to achieve regular grease refueling
Suitable for swing and rotational movement under heavy load and low speed
Non-absorbent and oil-absorbent, dimensionally stable
The thickness of the sliding layer is 0.3~0.5, which can be refined to improve the accuracy
The filler does not contain Pb, which meets environmental protection requirements
Used in axles, brakes, suspension systems, etc. of commercial trucks
