Oil-free bearing application
SF-2 added lubrication bearing:
Acidic polymethyl aldehyde with high wear resistance, bearing surface layout with oil storage pit must be coated with grease, especially suitable for high-load low-speed rotary motion, rocking motion and often Under load, it is not easy to form a fluid-lubricated part. Under boundary lubrication conditions, it can be used for a long time without oiling and maintenance. In the process, the service life of the bearing can be extended more. It is suitable for metallurgical machinery and mines. Machinery, hydraulic machinery, auto parts, construction machinery, agricultural machinery, etc.
Oil-free self-lubricating bearings:
The product is made of steel plate as the base, the middle layer is sintered with spherical bronze powder, and the surface layer is rolled with 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 and prevent sticking and slipping. It is widely used in various mechanical sliding parts such as printing machines, textile machines, hydraulic pallet trucks, tobacco machines, medical machinery, fitness equipment, micro-motors, automobiles, motorcycles, etc.
Metal-based inlaid solid self-lubricating bearings:
It is a novel lubricated bearing that combines the characteristics of metal bearings and the characteristics of self-lubricating bearings. It is loaded by a metal substrate, and the specially formulated solid lubricating material acts as a lubricant. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and strong self-lubricating ability. Traditional oil-impregnated bearings: Due to the advantages of low hum and self-lubrication, oil-impregnated bearings have become the new darling of computer CPU fan bearings, and the market demand is large. In addition, with the increasing demand for voice, oil-bearing bearings are The application of everyday household appliances is also expanding.
The basic requirements of the bearing for the material depend to a large extent on the performance of the bearing. Choosing the right material for the rolling bearing will have a major impact on its performance and longevity. In general, the main failure modes of rolling bearings are fatigue spalling under alternating stress and loss of bearing accuracy due to frictional wear. In addition, there are cracks, indentations, rust and other causes of abnormal damage to the bearing. Therefore, the rolling bearing 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 combination of materials and heat treatment processes.
