1. Shaft bearing of the bearing is solid: The bearing inner ring shoulders the shoulder and the interference realization axial solid. Practical for both ends of a solid bearing layout. Layout is simple, small outline size.
2. The elastic ring of the bearing is firm: The inner ring of the bearing is axially solid by the shoulder and lock nut. Can not bear the two-way axial load. Axial layout of small size.
3. The bearing lock nut is firm: The bearing inner ring is axially solid by the shoulder and the lock nut. And a stop washer anti-loose, quiet and reliable, suitable for high-speed, heavy load place.
4. Bearing end face thrust washers solid: the bearing inner ring by the shaft shoulder and shaft end ring to achieve axial solid. Shaft end ring is secured to the shaft end with a screw. There should be anti-loosening device. Applicable to the shaft end should not be cut thread or space is limited places.
5. Bearing the fixed set of solid: withdrawal of the clamping sleeve sets of essentials and the same. But the withdrawal of a special set of nuts, bearing easy loading and unloading, applied to a larger radial load, the smaller the axial load of the double row of spherical bearings in the optical axis firmly pinned sleeve of the radial hole size is compressed and clamped In the shaft, to achieve the axial bearing inner ring firmly.
6. Retention of the bearing on the firmly locked.
