Electric Motor Bronze Bushings
DALON self-lubricating custom bronze bushing 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 sintered bronze bushing to work under hydrodynamic conditions. which resulting in a very low friction coefficient and maintenance-free for general engineering applications.
Product Introduction
In order to meet the strict quality requirements of customers, we have been committed to improving production capacity and management level, so that the quality of Round Sintered Iron Bush, Industrial Disk filter, Sintered Wire Filter can be more effectively controlled and guaranteed during the production process. Whether in product development or marketing, we have achieved a development speed higher than the industry average. Make sure you genuinely feel free to send us your requirements and we are going to respond for you as soon as possible. We believe that a scientific and reasonable human resource strategy is conducive to the realization of the strategic goals of enterprise development, and the key to the formation of enterprise core competitiveness is the improvement of the level of enterprise human resource management.

DALON Electric Motor Bushing consist of a sintered bronze body. The main feature of Electric Motor Bushing is their porous design, which contains oil lubricant, which should be the viscosity decrease due to increasing operating temperatures due to friction, the oil leaks out. At higher speed, a lubrication wedge develops, which lowers the bushing's friction.
