Safety chuck according to its installation mode,it can be classified into flange and pillow mounted safety chuck.They are used for roller winding and unwinding.

During installation, there are some precaution should be pay attention to:
In safety chuck manufacture, it is already make sure its machining precision in the range of its tolerance. During installation, it should be care of its installation holes' position, and make sure axis concentricity calibration. After loading air shaft, alignment error should not exceed 0.3 degrees, it is good for air shaft and safety chuck's fast loading and unloading, and ensure the abrasion of air shaft and safety chuck least and prolong their service life.

If its tolerance too big, it needs to take care of material rack and machine vibrasion. This safety chuck is simple, practical and easy for installation. It is fast, safe, raliable and easy loading and unloading, which is suitable for frequent working. On the other hand, this safety chuck's driving part specification can be customized as different mechanical structure and characters.

Handong made safety chuck structure safe, and will not loose when rotating. Another sliding safety chuck can be moved in axial, through handwheel adjustment, so as to make sure web material in the center of roller, safe and accurate delivery torque.
