Construction Machinery Parts -Self Lubricating Bushing Sleeve for Excavators Hydraulic Cylinders
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.

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.
