Bearing the basic performance requirements of new applications
SF-2 boundary lubricated bearings plus: acid poly A with formaldehyde, with high wear resistance, bearing surface arrangement of the law must be fitted with a storage pit filled with grease, especially for high load low speed rotational motion, rolling motion, and often contain negative, the formation of lubrication is not easy to open and close the site, in the boundary lubrication conditions, without refueling for long-term use and maintenance, where the fuel Keshi to Gengduo extend bearing life , currently applicable to metallurgical machinery, mining machinery, irrigation machinery, automobile parts, construction machinery, agricultural machinery.
Oil-free self-lubricating bearings: The product is steel plate as the substrate, the middle layer of sintered bronze spherical powder, rolling surface of PTFE [ptfe] and a mixture made of lead. It has a low coefficient of friction, wear resistant. No oil from the lubrication and long service life, use it to reduce costs, reduce noise, to prevent the sticky, slippery. It is widely used in the sliding parts of machinery such as printing presses, textile machines, hydraulic truck, tobacco machine, pharmaceutical machinery, fitness equipment, micro-motors, automobiles, and motorcycles.
Metal matrix solid self-lubricating bearings mosaic: a metal bearing both the characteristics and features of the new self-lubricating bearings lubricated bearings, and loaded by the metal matrix, a special formulation of solid lubricant material as a lubricant. It has a high carrying capacity, impact resistance, high temperature, self-lubricating ability and so on.
The traditional oil bearings: The Noise Due to the low, the advantages of self-lubricating, oil-bearing has become the new darling of the computer CPU fan bearings, market demand; In addition, as people become increasingly demanding on the noise, oil-bearing Application of the daily household appliances are also being expanded.
Material bearing on the basic requirements of the work depends largely on the bearing performance. Select the suitability of materials bearing manufacturer, its performance and life will be greatly affected. In general, the main bearing failure modes is under the action of alternating stress fatigue spalling, and because of the loss of friction and wear Ershi precision bearings. In addition, there are cracks, indentations, bearing corrosion and other causes of non-normal damage. Therefore, the 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. Many of them from the material and the performance is jointly determined by the heat treatment process.
