GRAPHITE BRONZE BUSHING are an indispensable element of machinery, and DALON is professional manufacturer in P/M development and production. Since 2002, we produce and design high quality GRAPHITE BRONZE BUSHING for our customer requirements.
PRODUCTION PROCESS
The GRAPHITE BRONZE BUSHING sizes start from an interior diameter of 2mm and can go up to 250 mm, Length up to 80mm.
By P/M technology, The microroughness of the GRAPHITE BRONZE BUSHING surface enables amounts of lubricant to be transferred. To achieve the perfect surface properties for sliding function, process of impregnation under vacuum conditions by suitable lubricant can guarantee the capacity and the life of the bearing.
Standard material specifications include: SAE 841, ASTMB 438 Grade 1 Type II,
CuSn 6-6-3, Sint B 50 & Standard impregnating oil conforms to SAE 30 specifications
Sintered Bronze and iron based self-lubricating bushings are made of two different functions:
The metallic alloy structure which supports and transfers the mechanical loads
The oil lubricant or graphite contents which separates two surfaces in relative motion and to reduce friction.
