What is Oil free sliding bearings

Oil free sliding bearings use solid self-lubricating materials as polar surfaces to achieve sliding support of bearings without the need for any lubricants. Oil free sliding bearings have advantages such as self-lubrication, impact resistance, low noise, and wear resistance, which can improve the service life and reliability of equipment.
Oil free sliding bearings have the following characteristics:
1. No lubrication required: Oil free sliding bearings use self-lubricating materials, and lubricants are not required between friction surfaces, so there is no need to add lubricating oil, and the performance will not deteriorate due to the evaporation of lubricating oil.
2. Wear resistance: Self lubricating materials provide long-lasting lubrication, and the friction surface will not wear, thus having excellent wear resistance.
3. Vibration absorption and noise reduction: As there is no need for an oil film on the friction surface, small vibrations may occur during friction, which can absorb some mechanical energy, resulting in excellent vibration absorption and noise reduction performance.
4. Adaptation to environmental diversity: Self lubricating materials can be selected according to different usage environments, and can adapt to various environments such as extreme high temperature, low temperature, dry and wet, and chemical corrosion.
5. Customizable design: Self lubricating materials can be designed according to different bearing loads, speeds, temperatures, and other parameters, which can produce oil-free sliding bearings suitable for various high-performance mechanical equipment.
In summary, oil-free sliding bearings have the characteristics of self-lubrication, wear resistance, vibration and noise reduction, adaptability to environmental diversity, and customizable design. They are widely used in special environments such as high temperature, high pressure, low speed, and long-term uninterrupted operation.
In terms of application, oil-free sliding bearings can be widely used in various mechanical equipment, such as power, water pumps, metallurgy, machine tools, automobiles, molds, and various industrial equipment and wear-resistant equipment. Oil free sliding bearings mainly solve the lubrication problems existing in conventional lubrication bearings. On the one hand, they save the cost of using lubricants and can reduce maintenance costs; On the other hand, it can also isolate the pollution of lubricants to the environment and protect the environment. Meanwhile, oil-free sliding bearings are widely used in special environments such as high temperature, high pressure, low speed, and long-term uninterrupted operation.
