Graphite Bearings

Graphite bearings are mainly precision components in the shape of rings or sleeves. Depending on your actual conditions, they can be customized to meet your assembly needs. If you want to know more about the friction coefficient and bearing capacity, we will provide you with the appropriate answers and give professional technical advice.

Types of graphite bearings

Classified from the perspective of material composition:

Ordinary carbon bearings

Its carbon content can meet the general industrial applications, the cost is relatively low. And it is suitable for conventional equipment that does not have particularly high bearing performance requirements.

High-purity carbon-graphite bearings

With higher carbon content, more regular graphite crystal structure and better performance. You often use it in precision machinery with higher precision and stability requirements.

Bronze graphite bearings

It combines the high strength of bronze and the lubrication characteristics of graphite, with good bearing capacity and wear resistance. And you can widely use it in heavy duty industrial equipment that requires certain lubrication properties.

From the structural form:

Graphite impregnated bushings

It has the unique advantage of being compact and durable, and can effectively resist wear and corrosion. The graphite impregnation process makes it have excellent self-lubricating properties and good chemical stability, and can operate stably under harsh conditions.

Graphite ball bearing

It uses graphite ball as rolling body, has the characteristics of low friction, high precision. Suitable for high-speed rotation and high rotation flexibility requirements of equipment.

Graphite air bearings

With the combination of air as a lubricant and the self-lubricating properties of graphite, graphite air bearings achieve ultra-high-speed and high-precision rotating motion. You can mainly use it in high-speed rotating parts in high-end fields such as aerospace.

Advantages of graphite bearings

Outstanding self-lubricating performance

Due to the special layer structure of graphite, low friction coefficient, during the operation of the equipment can reduce energy loss. While it reduces the dependence on external lubrication. Such as in some difficult to add lubricating oil under special conditions, graphite bearings can still work normally.

Good thermal stability

It can maintain stable physical and chemical properties in a certain high temperature environment. Like in iron and steel smelting equipment, bearings made of carbon-graphite bearing materials can withstand high temperatures without deformation or damage.

Strong chemical stability

It has a strong resistance to many corrosive media. In the chemical production equipment, graphite bushings and carbon graphite bushing bearing can effectively prevent corrosion by acid and alkali and other corrosive substances, extend the service life.

Certain conductivity

In some specific electrical equipment, can play an auxiliary conductive or electrostatic export role. Ensure the safe operation of the equipment, improve the overall performance and reliability of the equipment. Reduce maintenance costs and downtime.

Uses of graphite bearings

In the field of machining:

The spindle of the machine tool uses graphite bearings, which can reduce friction and vibration. It will improve processing accuracy and surface quality, reduce tool wear, extend tool life, and improve processing efficiency.

In the automotive industry:

You can use graphite greases for wheel bearing with graphite sleeve bearing or graphite bronze bearing, etc.. It can adapt to various complex working conditions in vehicle driving. Effectively reduce friction and wear, improve the reliability and durability of wheel bearings, and ensure driving safety.

In power equipment:

The rotor bearing part of the generator uses bearings made of carbon-graphite bearing materials. And its good electrical and thermal conductivity helps to heat dissipation and stable operation of the motor, improve power generation efficiency and equipment reliability.

In chemical production:

The bearings of all kinds of pumps, mixers and other equipment use graphite bushing or carbon-graphite bushing bearings. It can resist the erosion of corrosive media, ensure the long-term stable operation of equipment. Reduce the frequency of equipment maintenance and replacement, and reduce production costs.

In the aerospace field:

You can use graphite air bearing in high-speed and high-precision rotating parts such as attitude adjustment mechanisms of satellites. This meets their strict requirements for low friction, high reliability and long life. Ensure accurate and stable operation of satellites in space and complete various tasks.

In some precision instrumentation, medical equipment and other fields:

Graphite ball bearings and graphite bracket bearings also play a key role, providing stable and reliable support for the precision movement of equipment. Ensure the accuracy and performance of the instrument. Meet the demand for high-precision equipment in scientific research, medical and other fields.
