On the production and application of oil-free bearings

- Jun 12, 2020-

       Oil-free bearings not only save fuel and save energy, but also have a longer working life than ordinary sliding bearings, so the scope of application is also very wide, so where are they used?

       SF-2 plus boundary lubrication bearing: acid polyformaldehyde, with high wear resistance, the bearing surface is regularly arranged with oil storage pit must be coated with lubricating grease during assembly, especially suitable for high load and low speed Rotating motion, rocking motion and often under load, opening and closing parts that are not easy to form fluid lubrication, under boundary lubrication conditions, can be used for a long time without refueling maintenance, and refueling during the process can extend the service life of the bearing , Currently applicable to metallurgical machinery, mining machinery, water conservancy machinery, auto parts, construction machinery, agricultural machinery, etc.

   Oil-free self-lubricating bearing: This product is made of steel plate as the matrix, sintered spherical bronze powder in the middle layer, and the surface layer rolled by a mixture of polytetrafluoroethylene [ptfe] and lead. It has the characteristics of small friction coefficient, wear resistance and corrosion resistance. Oil-free self-lubrication and long service life, it can reduce cost, reduce noise, prevent sticking and slipping. It is widely used in sliding parts of various machinery such as printing machines, textile machines, hydraulic trucks, tobacco machines, medicinal machinery, fitness machines, micro-motors, automobiles, motorcycles, etc.

   Metal-based embedded solid self-lubricating bearing: It is a novel lubricating bearing that combines the characteristics of metal bearings and self-lubricating bearings. The metal matrix bears the load, and the specially formulated solid lubricating material plays the role of lubrication. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and strong self-lubricating ability. Traditional oil-bearing bearings: Due to the advantages of low noise and self-lubrication, oil-bearing bearings have become the new darling of computer CPU fan bearings, and the market demand is large. In addition, as people have higher and higher requirements for noise, oil-bearing bearings are The application of everyday household appliances is also expanding.

  The basic requirements of bearings for materials depend to a large extent on the performance of bearings. The choice of materials for the manufacture of rolling bearings will have a great influence on their performance and life. In general, the main form of failure of rolling bearings is fatigue spalling under the action of alternating stress, and the loss of bearing accuracy due to friction and wear. In addition, there are cracks, indentations, corrosion and other reasons that cause abnormal damage to the bearing. Therefore, rolling bearings should have high resistance to plastic deformation, less friction and wear, good rotation accuracy, good dimensional accuracy and stability, and long contact fatigue life. And many of these properties are determined by the materials and heat treatment process.
