Through analyzing relative factors of effecting radialinternalclearance and effecting degree to matching, so that relative size parameters were controlled, matching quality was raised.
The article discusses the influenced factors of rolling bearing's radialinternalclearance, and fixes the optimal working radialinternalclearance of offset printing cylinder's rolling bearing.
The direct cause of this bearing 'failure was its improper assembly caused by improper maintenance procedure, and the root cause was too small internalradialclearance after mounting.
