Regarding the NSK bearing device; the requirements in all aspects are very detailed. Below I will analyze the following requirements for the host related parts in the NSK bearing device.
High-speed bearings require bearing position reversal system through fine dynamic balance; shaft and seat hole bearing parts should have higher dimensional accuracy and shape accuracy than usual; especially coaxiality and shoulder-to-seat or journal Straightness; while thinking about these problems; it is necessary to pay attention to the high-speed and high-temperature elements of the bearing work.
The shaft support system requires both high rigidity and the required quality as light as possible; in order to overcome this opposition; it can adopt measures such as reducing the appearance roughness and improving the appearance reinforcement to improve the support stiffness; using hollow shafts to reduce the system quality.
