Of course, if the imported bearings speed is very low, and pollution and humid environment, it is best to fill in skf bearing grease.
The standard offering more than 20,000 species of various types of bearings. Outside the Group in addition to rolling bearing manufacturing linear bearings, sliding bearings, bearing housings, ball and roller screw, textile machinery parts, keep the ring, machine tools and a variety of precision mechanical components. Extensive experience in these areas, and thus have the essential knowledge and expertise of the development, manufacture and application of advanced engineering products. Small in size as weighing only 0.003 grams of miniature bearings, large 34-ton giant bearings. In addition, a series of bearing maintenance tools, grease and bearing monitoring equipment (bearings heater, drawing, etc.), so that users bearing a more cost-effective to achieve the worry-free operation.
Bearings are precision components, SKF bearings and grease pollution, will not be able to run. Bearings, sealed maintenance-free and grease all, at least 14% of the pollution is only a small part of all early bearing failure significantly due to bearing. The bearing has an excellent manufacturing and design capabilities, able to provide a variety of adverse working conditions of sealing solutions.
Grease the chemical anti-Qing acid with oxygen in the air, it first is the consumption of antioxidant additives in the grease, but to a certain extent, the organic acids generated by corrosion of metal components and destroy the structure of the fat, so the drop point decline in the base oil viscosity increases and the variation of mobility. A large number of tests showed that the higher the temperature, the life of the grease drop more obvious. Such as the temperature is 90 ~ 100 degrees, the temperature rise of 19 degrees, the life of the resin was reduced by approximately half, 10 to 150 degrees, 15 degrees the temperature is increased, the life of the fat will drop by half.
In addition, the grease to use in moisture, dust and harmful gases, etc. also make it an important factor in deterioration. For example: fat mixed with copper, iron, lead and bronze wear particles would be the oxidation of fat act as a catalyst. In short, grease failure of many reasons, and sometimes may be caused by a reason, but more of a variety of factors with the result, or a reason as a breakthrough, then the combined effect of other reasons.
Grease in use will also be subjected to mechanical shear and centrifugal force, under the action of grease will be thrown off the friction interface and its oil separator, resulting in reduction in grease oil, cone penetration decreases and hardened to a certain degree grease will be a total failure; mechanical shearing, the structure of grease love to destruction (such as soap fibers torn off or orientation), causing its softening, consistency decreased and analysis of fuel increase, eventually leading to failure. Under normal circumstances, the grease to use transmitting speed 2000r/min, its life will be reduced by about half. Under high shear stress, speed doubling the service life is only equivalent to the original life of 1/10.
The free base soap grease manufacturing process is not excess alkali with the fatty acids in the role; free organic acids is not been in the manufacturing process of saponification of fatty acids, or alkyl fat itself contains acid (naphthenic acid), or mineral oil in the fat oxidation or saponification decomposition products.
Although you can install a "free" all kinds of skf bearing seal, bearing the early failure is still 36% is incorrect grease and improper use. Advance of the inevitable failure of any improper lubrication bearing in the normal life. Machinery and equipment bearing is usually the most difficult part of the work, there is no fixed lubrication is a problem. Artificially maintained, it is impossible to achieve, automatic lubrication system can be developed to achieve the best lubrication. Grease, tools and effective lubrication technology will help to significantly reduce downtime.
