Effectiveness effectiveness of NSK bearings are divided into normal and abnormal results, then how do irregular have? Here to introduce you to give rise to the effectiveness of a number of reasons.
1, axis skewed (wrong) abutment on the mating surfaces of the shaft and the case is not vertical
2, shell when installing NSK bearing two or more different hole axis
3, poor axis of rigid, bent occurs under load is too large
4, bearing two fixed end-span larger, rising temperature caused by thermal elongation of shaft bending of statically indeterminate nature of the axis
5, bearing poor accuracy, well more to You Yuan bearing at one end and a larger
6, poor bearing rigidity. Uneven or housing bottom
7, mounting surface fall into hard particles or dirt
8, opposite to the stress concentration of Plummer block bearing ring when the clamp clip flat
9, improper rebar uranium bearing shaft tolerance of inequality
10, has holes in the bearing or clamping screws, fasteners, local augmentation
11, support with grooves or printed close to the NSK bearing Raceway
