We have the courage to seize the opportunity to meet the challenge of rapid economic development in the new era. We have rich experience in overseas self-export, and we have received good results.
DALON SINTERED BRONZE BUSHING INTRODUCTION:
DALON self-lubricating Powder Metallurgy Bushingg are manufactured of pressed copper and tin powders by sintered technology and impregnated with lubricating oil and high porosity (20-25% in volume).
The oil contained in the porosity provides a constant lubrication between bearing and shaft, the system does not need any additional external lubricant, allows this type of Powder Metallurgy Bushing to work under hydrodynamic conditions. which resulting in a very low friction coefficient and maintenance-free for general engineering applications.

Bronze based | SAE841 ASTM B438-70; SintA50 | Cu87.5~90.5,Fe1.0max,Sn9.5~10.5; CuSn663 |
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.



POWDER METALLURGY 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 POWDER METALLURGY BUSHING for our customer requirements.
POWDER METALLURGY BUSHING TO HEAVY-DUTY INDUSTRIAL APPLICATIONS
POWDER METALLURGY BUSHING have superb values in all engineering applications.
The properties of POWDER METALLURGY BUSHING are significantly defined by the high level of precision in manufacture and the porosity of the sintered material. POWDER METALLURGY BUSHING are deployed in almost all fields of industrial area, which from simple plain bearings used in wide range of engineering to high-load bushings in heavy-duty industry.
