The principle of eccentric screw

The eccentric screw is a tool that uses the physical and mathematical principles of the oblique circular rotation and friction of the object to tighten the device parts step by step.

Replacing the eccentric screw is for adjustment during positioning, and does not affect safety. There is no problem with the above-mentioned maintenance operations during four-wheel alignment.

If the inclination angle of the wheel exceeds the standard range of use, it can only be adjusted by using the eccentric screw, which can ensure the normal wheel data and avoid tire wear.
