NSK bearings in the operation process, failure is common, so don't make a fuss over it. Failure of judgment and treatment is very important. Today, we explain the common problems and bearing the dismantling of means.
 
1. NSK bearing temperature
 
In the operating agencies, installation of the bearing parts, allowing a certain temperature, when touching the shell, should not feel hot to normal, and vice versa, bearing temperature.
NSK bearing temperature reason: the oil quality requirements or to deteriorate, the viscosity of oil too high; Body assembly close (the space is insufficient); Bearing assembly close, bearing the axis of rotation on collar or shell, load NSK bearing too maintains a or body pieces, etc.
 
2. NSK bearing noise
 
NSK bearings in the operation of to allow a slight noise, if excessive noise or unusual noise or collapse, then NSK bearing failure.
NSK bearing noise is more complex reasons, one is the bearing surface wear both inside and outside the ring. Because the wear and tear, NSK bearings and the shell, bearing and the relationship between the collar of damage, leading to deviate from the correct position on the axis of the shaft produce different ring. When bearing fatigue, metal chip surface, but will also increase NSK bearing radial clearance produce different ring. In addition, NSK bearing insufficient lubrication, form of dry friction, and bearing will have broken abnormal voice. Loose NSK bearing wear, cage looseness damage, also have different ring.
 
NSK bearing installation method
 
NSK bearings and bushings general, chair, NSK bearing hole general clearance fit transition, two-way thrust bearing rings should be fixed on the shaft, in order to prevent the relative to the axis of revolution. NSK bearing installation method, under normal circumstances, in most cases axis, so the inner circle of shaft co-opted, NSK bearings and bearing clearance fit WaiWu.
 
NSK bearing installed, you should check the ring and bushings the center axis vertical. Dial indicators in the fixed, will face touch NSK bearings, axis of rolling bearing the way more than the multiplier, and observe qianbanbiao pointer, if the pointer deflection, explain ring and the axis of the collar not vertical center line. Box shell hole deep, head can also use dial-up test instrument of extension. NSK bearing installation is correct, the seat can automatically ADAPTS to the body, to ensure that the agency is to be located in the roll up and down the road. If the outfit, not only NSK bearing not normal work, and work with severe wear will face. Due to the differences and ring stay ring bearings is not very clear, congress should be careful, don't make a mistake. In addition, the bearing and a hole with circle between 0.2 0.5 mm of gap, to compensate for parts processing, installation errors causes is not accurate, the operations center NSK bearing offset ring, this space, to ensure its automatic adjustment, avoid to contact friction normal operation. Otherwise, NSK bearings, will cause serious damage.
