Product description

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 mallet 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.

Type M ball knobs are a more economical solution, however, the pulling off force is less predictable.

Since there are no parting lines in the middle of the ball, the ball knob DIN 319 is an excellent choice for user friendly applications.
