Graphite Plugged Solid Lubricant Bearings With High Load Capacity Wide Usage
1. Product Description
Graphite Plugged Solid Lubricant Bearings With High Load Capacity Wide Usage based on brass CuZn25Al5Mn4Fe3, with extremely high load capacity, good anti-wear and lower friction.It offer technically and economically favorable bearings soluions.WHB can offer different types of bronze alloys according to the required life time,service etc.The tolerance is much tighter than wrapped bronze bushes.

3. Application
Graphite Plugged Solid Lubricant Bearings With High Load Capacity Wide Usage are widely applied in port machinery, excavator machinery,building machinery etc.
4. Advantages
This solid lubricant bearings are suitable for reciprocating, oscillation or intermittent motion where oil film is hard to be formed.Because of the linear coefficient expansion of the solid lubricant is bigger than that of the metal basement,when the solid-lubricant-inlaid bushing starts to operate,the oil film can transfer to the corresponding friction set to make out self-lubriant.So the bushing can be used in places where the oil or grease can't be added.It can make out the self-lubricant function even though under high load conditions.
