Grease lubrication is not in keeping with current casting machines bearing grease with molybdenum disulfide is considered resistant against high temperature grease, high ambient temperature. Know it base oils are made from petroleum products, plus a small amount of molybdenum disulfide additives for high temperature resistance, its temperature limit is 120 degrees centigrade. Cast according to machine the bearing operating temperature up to 200 ° c, far exceed the temperature limits lubricating grease. Under high temperature conditions, SKF bearings grease based oil be attenuated and gradually evaporated, the rest of the blend, dust, carbon residue, molybdenum disulfide as solid block coagulating on the insistence of rolling bearings, has not only lost its lubricating role, also impedes the functioning of rolling bearings wear quickly, up to 2 weeks is down, remove the bearing wash-for new oil.
Solid lubrication full information content, FAG bearings temperature in width. Release uniform, has good of since lubrication performance and occlusal sexual, can effective to protection axis neck, reached durable of using purpose applies Yu in high temperature, and low speed, and overload, and dust large, and water rushed pour and has impact vibration of environment Xia run, this class bearing can broad application Yu mine machinery, and metallurgical, and oil, and chemical, and food, and textile, and paper, and printing and dyeing, machinery equipment of scroll and sliding bearing parts.
Pour into mixing with the vacuum ladle out furnace, producing aluminium in liquid. After Proportioning and skimming flows to the ingot casting machines casting molding, NSK bearings forming solid aluminum ingots, the production of aluminum ingot stackers stacking. In order to improve production efficiency, aluminum ingot forming necessary before using large quantities of cooling water for cooling, aluminum liquid in the cooling process an enormous amount of heat energy released into the cooling water, hot water vapor.
Many of TIMKEN bearings are grease lubricated, casting machines bearing at high temperature and steam environment. Add grease will melt because of the high temperature overflow within a short time removed, care and maintenance difficulties, equipment appearance and health are also easy to wipe. Then steel bearings in corrosion rusted easily in the hot, humid environment, the failure rate is very high, bearing high equipment maintenance costs, often troubled by the following two problems in operation of equipment.
Inject grease into the design on a regular basis on each turn the bearing grease nipples facilities for oil operations difficult to achieve high temperature ingot casting machine runs continuously, move the spindle, spindle, bearings turn the spindle device installed on the unit housing. Grease removal must stop at Shell, grease gun with oil pressure people. And the whole machine oiling up to more than 30 points, oiling of the provisional operation and maintenance could not achieve such a cumbersome operation, had to hand in thin oil pot of cream poured over run-bearing external, lubricating oils have very little access to bearing friction, most of INA bearings friction.
