Jintai wide temperature self-lubricating bearings, solid lubricant content sufficient to release even with good self-lubricating properties and seizure resistance, can effectively protect the journal, achieve a lasting purpose. Applies to operate at high temperature, low speed, heavy, dusty, water shower and there is shock and vibration environments, such Jintai bearings can be widely used in mining machinery, metallurgy, petroleum, chemical, food, textile, paper, printing and dyeing rolling and plain bearing parts of machinery and equipment.
Casting machine bearing temperature and water vapor is in the environment, many bearing grease, grease add a relatively short time because of the high temperature and melt overflow removed, maintenance difficulties, equipment surfaces health is also difficulty swabbing. Further steel bearings in hot, humid environments can easily rust corrosion, failure rate is very high, higher equipment maintenance costs, equipment operation subject to the following two problems often troubled.
Fueling operation is difficult to achieve a high temperature continuous operation pulling ingot casting machine, shift spindles, then the spindle, turned spindles and other devices are installed in the unit housing design regularly inject grease nipple facilities on each rotation of the bearing, must stop when oiling housing demolition, oil grease gun pressure on people. And the whole point oiling up to 30 multiple, long-term operation and maintenance can not achieve this cumbersome oiling operation, had a handheld shower pouring dilute oiler in the operation of external bearing sleeve, lubricating oil is difficult to enter the bearing friction between large portion of the bearing in the frictional state.
High ambient temperature, grease molybdenum disulfide grease suited to the current Rolling casting machine used is considered to high temperature grease, we know it is based on oil are petroleum products, plus a small amount of high temperature molybdenum disulfide additive, its temperature limit i.e. 120 ℃. According to the measuring caster bearing operating temperature up to 200 ℃, far beyond the grease temperature limit. In such high temperature conditions, the grease base oil becomes thinner and gradually evaporated, leaving carbon residue, molybdenum disulfide, dust mixed into a solid block in the rolling bearing holder solidified, not only lose its lubricating effect, also impede the normal operation of the rolling bearing and wear out quickly, up to two weeks would have shut down, remove the clean ones Jintai bearing grease.
