Information

When ball knobs DIN 319 type L and M are used the shaft does not require a thread. During mounting, easy blows with a soft hammer are sufficient to drive the knob into place, the shaft end should be slightly rounded or chamfered (30°).

Before the assembly of the ball knobs, type L the tolerance ring is to be inserted into the drilling. Further it is to be noted that the knob is put on perpendicular and / or axially parallel. Otherwise the ball knob may break.

Ball knobs, type M are a more economic solution.
