Hello,


If the individual springs in the spring package are not lubricated and glide badly and differently, then the spring leaves, which glide easily, must additionally absorb the force from the leaves, which glide badly. This overloads them.

Wherever a relative movement takes place, friction and wear are created. Therefore, it must be lubricated there.

In the picture you can see how the upper spring leaf worked into the lower one, because the spring ran dry. About 0.3 millimeters!
