Oily Sintered Stainless Steel Self - Lubricating Bearing Bush for Shaft
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
We depend on sturdy technical force and continually create sophisticated technologies to meet the demand of high temperature high load dry running sleeve bearing, disk filter, brass pneumatic muffler. We will start from your specific requirements and actual situation, sincerely serve you and make you satisfied. We have been convinced that with joint attempts, the business enterprise between us will bring us mutual benefits. We believe that companies that combine size and flexibility to adapt to rapidly changing market conditions can become the biggest winners.
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.
