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 develop new technology Stainless Wire Mesh Steel filter, Sintered Bronze Spherical Bushing, sintered metal bearing, enhance our core competitiveness, and contribute products to society that meet the requirements of the times. A number of technologies pioneered by the company have filled the gaps in the country and broke the monopoly of foreign technology. Our company is based on the domestic market and actively explore the international market. We attract all kinds of outstanding talents with advanced technology and advanced management concepts to join the group and seek common development. We have formed a perfect quality control system with our own characteristics by combining the problems that arise during our development and continuous improvement.


DALON Oil Impregnated Bearing made by SAE 841 Sintered Powdered Metal - commonly used in machinery components, self-lubricating pump parts, turbine blades, office machines, home appliances, medical equipment, farm equipment and lawn and garden equipment.

Storage of Oil Impregnated Bearing – 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 Oil Impregnated Bearing – Custom Oil Impregnated Bearing 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.
DALON Oil Impregnated Bearing consist of a sintered bronze body. The main feature of Oil Impregnated Bearing 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 Oil Impregnated Bearing 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.
- High load oil-embedded Sleeve Bearings: This kind of Oil Impregnated Bearing increased iron content which makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings. Also they running at lower speeds
- High load Ultra low Friction oil embedded sleeve bearings: This kind of bearings used for frequent starts and stops in high load applications.
- Food Industry oil embedded sleeve bearings: These bearings used oil is suitable for incidental contact with food.
- Multipurpose sleeve bearings: These bronze bearings with lead are strong, wear resistant and excellent at handling shock loads.
- Oil filled SAE841 Bronze bearings: Sintered bronze powder SAE841 without lead impregnated with SAE 30 oil to make this material self—lubricating.
- SAE 660 Bronze bearings: These bearings offering excellent antifriction qualities, SAE660 bronze also offer goods strength and wear resistance. It’s often used for bearings, bushings, and thrust washers.
- High temperature Graphite filled 841 bronze Bushing: These bushing have an excellent alternative to oil filled bushing, graphite filled bronze provides dry lubrication in temperature as high as 370℃
