NBR Rubber Bush Black Silicone Bushings for Pump Valve Coupling
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.

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 Pump 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.
We can easily usually fulfill our respected customers with our very good top quality, very good price tag and excellent support due to we have been more expert and much more hard-working and do it in cost-effective way for NBR Rubber Bush Black Silicone Bushings for Pump Valve Coupling. We always focus on and continue to meet the needs of customers, the pursuit of customer satisfaction and success. Our company always pursues the principle of honesty and belief, and always regards the requirements and satisfaction of customers as the goal of our efforts.
