Self Lubricated Bearing Sleeve of Hydraulic Cylinders for Excavators
DALON self-lubricating sintered 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
With the help of a strong research and development team and long-term market research, we have developed original Wire Muffler, bronze flanged sleeve bearing, Porous Plastic Filters that meet the market demand and are loved by consumers. Thanks to our partners for their long-term care and support for our cause, let us continue to cooperate sincerely and create new value for the industry. We will march towards a higher and farther goal for the future. We always adhere to the guiding ideology of technology supporting development and innovation leading the future. Our company's current stage goal is to continuously improve the brand effect and let customers trust us unreservedly.
DALON BUSHING INTRODUCTION:
DALON Self Lubricating Bearing in Powder Metallurgy consist of a sintered bronze body. The main feature of Self Lubricating Bearing in Powder Metallurgy 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 Self Lubricating Bearing in Powder Metallurgy 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.
