graphite self lubricating oil bearing non oil bushing graphite copper sleeve
Metal-polymer self-lubricating composite bearings
Solid self-lubricating bearing materials consist of high strength metal with solid lubricants embedded, the metal has high load capacity and solid lubricants provided low friction during the operation, this construction reduces maintenance cost for both bearing and machinery. Material Properties are as follows:
Allows maintenance-free and long-life operation;
Suitable for high static and dynamic loads;
With low and smoothly coefficient of friction and without stick-slip effects;
Suitable for dirty, corrosion, impact load and edge loading;
The base material provided a good shock-absorbing capacity;
Can be used over a large temperature range;
With low wear rate and long life service.
Suitable for reciprocating, rotating and oscillating movement with start frequency
and difficulty to form oil film occasions;
Widely used in injection molding machines, automotive molds, cylinders, gearboxes, gas turbines, turbines, crane supports and other mechanical equipment
