The self-lubricating oilless flanged graphite bronze sleeve bushing is a specialized mechanical component designed to provide smooth and reliable operation without the need for external lubrication. This type of bushing is crafted from graphite bronze, a material that combines the benefits of both graphite and bronze, resulting in exceptional wear resistance, corrosion resistance, and self-lubricating properties.

The flanged design of the bushing allows for easy installation and secure attachment to machinery components. The graphite bronze material is inherently self-lubricating, meaning it can maintain a low coefficient of friction and reduce wear even in the absence of external lubricants. This eliminates the need for regular lubrication maintenance, reducing downtime and improving overall system efficiency.

The self-lubricating oilless flanged graphite bronze sleeve bushing is ideal for applications where lubrication is difficult or undesirable, such as in high-temperature or high-pressure environments. It is also suitable for applications involving frequent start-stops, high-speed rotation, or heavy loads, as it can maintain a consistent level of performance even under extreme operating conditions.

In summary, the self-lubricating oilless flanged graphite bronze sleeve bushing is a reliable and efficient solution for reducing friction and wear in mechanical systems. Its unique combination of material properties and design features enables it to operate smoothly without the need for external lubrication, improving system performance and reducing maintenance requirements.

These oilless bushings are self-lubricating bearings composed of high strength brass alloy bases manufactured with advanced casting technology and built-in solid lubricants. They can be combined with different types of solid lubricants depending on the conditions of use.

Solid graphite plugged bronze oilless bushings

The base of the solid lubricating bearing should be determined according to the working conditions of the bearing itself. The more commonly used materials are high-strength brass, tin bronze, castings, etc. There are two main types of embedded solid lubricating materials, one is natural black lead, Artificial graphite is synthesized with MoS2, and the other is synthesized with . According to the bearing's own working conditions, through the combination of different metal substrates and embedded solid lubricants, it can ensure that the product can meet various temperatures, loads, motions and media. Special needs under the conditions, while ensuring stable and reliable work.

JDB solid graphite plugged bronze bushings

JDB solid graphite plugged bronze bushings are widely used in metallurgical continuous casters, train supports, rolling equipment, mining machinery, ships, steam turbines, and other high temperature, high load, low speed and heavy load occasions; in low load, high temperature, medium speed and other occasions, such as fireplaces Door, oven raceway, rubber machinery, light industry machinery, machine tool industry; its end face can be welded and installed with the base body, so it is suitable for metallurgical machinery, construction machinery, oil transportation machinery and other fields that cannot be refueled; in lifting machinery The supporting parts are especially adapted, such as hoist support, crane support, and excavator support.

Application characteristics of oilless bushing:

It is especially suitable for rotating motion under heavy load and low speed, rocking motion and parts that are not easy to form fluid lubrication under load; it can be used for a long time under boundary lubrication conditions without refueling maintenance, and refueling in the process can make the bearing use The service life can be more extended; the plastic layer on the surface can leave a certain margin during the forming and processing of the shaft sleeve, and can be processed by itself after being pressed into the opening to achieve a better assembly size.

At present, it is mainly used in metallurgical machinery, mining machinery, water conservancy machinery, automobile chassis, construction machinery, agricultural machinery, steel rolling machinery, etc.

1. The mixture of modified polyoxymethylene (POM) and lead is 0.3~0.5mm, which has high wear resistance, and has a low friction coefficient even in the case of instantaneous oil shortage. There are regularly arranged oil storage pits with spiral angles on the bearing surface, which must be covered with lubricating grease during assembly.

2. The copper powder layer is 0.2~0.3mm, which has good carrying capacity and wear resistance, and good thermal conductivity can transfer the heat generated during the operation of the bearing in time. The composite material can penetrate into the gap of the copper powder ball to improve the bonding strength.

3. Low carbon steel 0.4~2.2mm, improve the bearing capacity and heat transfer effect.

4. Copper/tin plating layer, copper plating layer 0.008mm, tin plating layer 0.005mm, so that the bearing has good corrosion resistance.
