1. Shaft shoulder fixation
The inner ring of INA bearings
relies on the shaft and interference for axial fixation.
This method is applied to the fixed supporting structure of both ends.
At the same time, the structure is simple and, the size of the exterior contour is small.
2. Circlip fixation
the inner ring of INA bearings achieves axial fixation by the shaft shoulder and the lock nut.
This method can afford a two-way axial load.
The size of axial structure is small.
3. Lock nut fixation
the inner ring of INA bearings achieves axial fixation by the lock nut and the shaft shoulder, and with washers anti-loose. It is safe and reliable, suitable for high-speed, heavy load.
