Self-lubricating Bearing Principles and Maintenance

Self-lubricating bearings use wide temperature, solid lubrication material content is sufficient, open and release uniform, with excellent self-lubrication performance and bite, can effectively protect the shaft neck, to reach a long-lasting purpose of use. Suitable for high temperature, low speed, heavy load, large dust, water shower and shock vibration environment, can be widely used in mining machinery, metallurgy, petroleum, chemical, food, textile, paper, printing and dyeing machinery rolling and sliding bearing parts.

Aluminum liquid produced by the aluminum electrolytic cell, absorbed by vacuum bag and poured into the hybrid furnace, after matching and desage, into the aluminum ingot casting machine cast molding, the formed solid is called aluminum ingot, the production of aluminum ingots by the stacker stacking. In order to improve production efficiency, aluminum ingots must be cooled with a large amount of cooling water before forming, during the cooling process, the aluminum liquid of huge heat release into the cooling water, hot water vapor. Casting machine bearings are in the high temperature and water vapor environment, bearings are many grease lubrication, added grease in a short period of time due to high temperature and melting overflow removal, maintenance and maintenance difficulties, equipment surface hygiene is also easy to wipe. Then there are steel bearings in the hot, humid environment is easy to easily easily easily easily easily easily erode rust, failure rate is very high, equipment maintenance costs are high, equipment operation is often plagued by the following two problems.

Oil supply operation is difficult to achieve high temperature continuous operation casting machine pull ingots, transfer ingots, ingots, ingots and other devices are installed in the unit housing, each rotating bearing designed with regular injection of oil grease nozzle facilities, oil injection must stop to remove the housing, with oil gun pressure human grease. And the whole machine filling points as many as 30 places, long-term operation and maintenance can not achieve this cumbersome oil injection operation, had to hand in a thin oil pot poured in the operation of the bearing sleeve outside, lubricants are difficult to enter the bearing friction between the sub-parts, most of the bearings in a friction state.

High ambient temperature, grease lubrication does not adapt to the current casting machine rolling bearings used in the disulfide grease is considered to be resistant to high temperature grease, we know that its base oil is petroleum products, plus a small amount of high temperature-resistant disulfide antimony additives, its temperature resistance limit is also 120 degrees C. It is measured that the bearing temperature of the casting machine can reach 200 degrees C, which has far exceeded the temperature resistance limit of grease.
