Introduce the importance of NSK spherical roller bearing lubrication and maintenance

Effect of lubrication of the bearing lubrication of NSK bearings, especially the fatigue life of rolling bearing, friction and wear, temperature rise, vibration and so on have important influence. No normal lubrication, spherical roller bearing cannot work. And we have been analysis in the previous articles, the cause of the bearing damage shows that about 40% of the bearing damage is related to bad lubrication. Therefore, good lubrication of the bearing is the effective measures to reduce the bearing friction and wear. In addition, NSK bearing lubrication and cooling, a variety of action such as rust, seal, moderate impact. Another is likely to be the size of the diameter of axle and bearing hole measurement inaccuracy or cooperate with surface roughness, do not meet the standard requirements to cause excessive interference fit, the bearing race is being squeezed from a large, resulting in the radial clearance of bearing itself is reduced, the bearing rotating difficulties, fever, wear or jammed, caused serious bearing inner and outer race during installation. All bearing NSK bearing friction resistance of basically contains two hardened steel rings, multiple hardening of ball or roller, roller or roller and a separation or maintaining aircraft separation. These types are in use is divided into many types. Some types, such as bearings, needle column may not have the internal ring, roller directly on hardening axis movement. In practice, it is necessary to use there is more than the recommended amount of grease. When the required torque low, only very few can complete pair of roller bearing grease lubrication. When the speed is very low and bearing exposure in dust or moisture, bearing might almost be filled. NSK bearings under the condition of high speed and high temperature usually need more frequent than in general lubrication.
