The new application and the basic requirements of the bearing performance
SF-2 plus boundary lubricating bearings: acidic poly A with formaldehyde, has the very high wear-resistance, bearing surface is arranged regularly with the oil pit assembly must be coated with grease, especially suitable for high load low speed rotation, swing and often in load, opening and closing and difficult to form hydrodynamic lubrication the site, under the condition of boundary lubrication, and can be used for a long time without refueling and maintenance, and in the process gas can make the service life of the bearing can be prolonged to more, metallurgical machinery, mining machinery, hydraulic machinery, auto parts, construction machinery used at present, agricultural machinery etc..
Oilless self-lubricating bearing: the product is made of steel plate as the substrate, the middle layer of sintered bronze spherical powder, a mixture of surface rolling Teflon [ptfe] and lead and made. It has a low coefficient of friction, wear and corrosion resistance. Oil free self lubrication and long service life, use it can reduce costs, reduce noise, prevent the stick, slip. Sliding parts which are widely used in various machinery such as printing machines, textile machines, hydraulic truck, tobacco machines, pharmaceutical machinery, fitness equipment, micro motor, automobile, motorcycle etc..
Metal matrix mosaic solid self lubricating bearing is a novel lubricating bearings: a combined metal bearing characteristics and self lubricating bearing characteristics, is composed of a metal base load, special solid lubricant formulations of lubrication. It has high carrying capacity, impact resistance, high temperature resistance, self - lubricating ability and other characteristics.
Traditional oil bearings: because of the noise is low, the advantages of self lubrication, oil bearing has become the computer CPU fan bearing force, large market demand; in addition, as more and more requirement of noise, application of oil bearing in daily household appliances are also expanding.
The performance of the basic requirements of the material bearing depends largely on the bearing. Selection of manufacturing is suitable material for rolling bearings, will have a great effect on its performance and lifetime. In general, the main failure forms of rolling bearing fatigue spalling force is under the action of alternating, and due to friction and wear and the bearing precision loss. In addition, there are cracks, indentation, rust and other causes of bearing abnormal damage. Therefore, the rolling bearing should have high resistance to plastic deformation, friction and wear less, rotation accuracy, good dimensional accuracy and stability, and longer contact fatigue life. And many of the performance is determined by the material and the heat treatment process..
