Usually long spindle bearing life

Replay:

Spindle bearing life and ordinary bearing different concept of life. The ordinary life of the bearings, usually refers to failure, such as pitting. The spindle bearing life refers to the rotation accuracy decreased, not pitting that step. Spindle bearings are generally into groups using a single bearing load is not very high, which is given to the spindle rotation accuracy, design ideas required to be taken to reduce the use of load bearing. Bearing life is influenced by the conditions of use there are a lot of factors, spindle bearing life is difficult to calculate, predict general anticipation of Mathematical Statistics, experience. General use 2-3 years should be no problem, some of the machine can be used for more than 10 years, of course, the accuracy will decline.
