Electrical Apparatus with Wall Bushing Capacitor
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
Our company's purpose is to market-oriented, according to customer demand development, production of high-quality Bronze Bushings, Sintered Iron Bushings, metric drill bushing. After several years of market cultivation, our company has formed its own unique development mode and unique business positioning. The company insists on "people-oriented", advocates "happy work", and takes human resources as the first resource for development. We firmly believe that long-term business success can only be rooted in integrity and enthusiasm. Cooperation, exchange and communication are not means, but a way of mutual benefit to create a virtuous business circle. After years of development and operation, our company has established a good cooperative relationship with man enterprises.


DALON Electrical Bushing consist of a sintered bronze body. The main feature of Electrical 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.
The powdered metallurgy process is a mass production process that can reduce costs to a level that can be startlingly low when compared to CNC machining. An added benefit of the sintered Electrical Bushing are the unique pores that are formed in the structure of the metal. These pores can serve as a reservoir for lubricant, providing a passage to the bearing surface. This unique feature adds the benefit of self-lubrication to many powdered metal bearings.

Storage of Electrical Bushing – These bearings must be stored in non-absorbing containers. Do not store in paper or cloth container. Do not store in cardboard boxes. The best containers are made of plastic or metal.
Supplementary Lubrication – Additional lubrication can be provided through the use of oil soaked felts, wicks, etc. or by periodic oiling. A unique advantage of this type of bearing is that it does not require any grooving or holes to distribute the oil across the bearing face due to the microscopic pores in the bearing material.
Custom Made Electrical Bushing – Custom Electrical Bushing can be designed and manufactured according to customer specifications, including requirements for special dimensions and/or materials. Please offer your drawings by email and we will made a quotation quickly.







Every customer's satisfaction with the use of Electrical Apparatus with Wall Bushing Capacitor will bring us a great sense of achievement. We always believe that the temperament and quality of producers are contained in the products and all the good qualities are made up of details. We actively implement and introduce international management standards and establish a complete quality assurance system.
