The bearing lubrication and maintenance
« on: March 12, 2014, 02:50:41 AM »
Lubrication bearing is necessary for normal operation.   Lubrication on the fatigue life of rolling Parameter Of KOYO Bearing hxxp: www. abtbearings. com/KOYO-bearings. html, friction and wear, vibration and so on have important influence, about 40% of the bearing damage is related to bad lubrication.   Bearing lubrication is the purpose of make a layer of oil film is formed between the bearing rolling surface, to prevent direct contact with the metal and metal.   The role of lubrication of rolling bearings is as follows:
1.   Reduce the friction and wear, prolong bearing's life;
2.   Get rid of friction heat, prevent the bearing temperature rise is too high;
3.   To prevent foreign invasion, have the effect of sealing;
4.   To prevent the metal corrosion. 
A, the comparison of grease lubrication and oil lubrication:
Almost all rolling bearings with grease or oil lubrication, there are also some special purpose with platinum disulfide, graphite and other solid lubricant lubrication.   In grease lubrication and oil lubrication, grease lubrication with the most, about 80% of the rolling bearing grease is used.   Compared with oil lubrication, grease lubrication has the following advantages:
1.   Lubrication device is simple;
2.   The grease is not easy to leak, bearing seal structure is simple;
3.   Bearing maintenance, maintenance is convenient;
4.   Grease sealing function, can prevent external dust, moisture and other impurities into the bearing;
5.   Easy to improve the purity of the machinery.   Grease lubrication fault is bearing friction, heat dissipation is not good, allowing the rotational speed is low.
