Some knowledge about NSK bearings

SK in the bearing has a bearing structure for spherical roller bearings, the spherical roller bearing is enough, because of the spherical roller bearing outer ring raceway curvature center and bearing center consistent, so has the heart function. In there was a deflection axis, a hood, can automatically adjust, not to increase the bearing burden. Spherical roller bearings of NSK bearings may withstand the bigger radial load, at the same time also can absorb a certain amount of axial load. This kind of bearing outer ring raceway is spherical shape, so has self-aligning properties, when bearing load bending or leaning and make the center line of the center line of the inner ring and outer ring relative tilt is not more than 1 ° ~ 2. 5 °, the bearing can still work. Can compensate the axial bending deformation and bearing installation parts formed after the concentricity error. Japanese NSK bearings rolling bearing in the process of use due to the quality of itself and the external conditions, the cause of its bearing capacity, rotational accuracy and antifriction performance will change, in fact anything in use will reduce the life span. NSK bearings when performance index is lower than the use requirement and when not working, is called a bearing damage or failure, bearing in the event of damage, such as accident happens, there will be stalling its machines, equipment, functional damage and other anomalies. So you need to investigate causes in a short time, and take corresponding measures, of course, the rolling bearing damaged the damage is much more complex than general machinery parts, rolling bearing damage is the number of forms, the characteristics of complex reasons.
