Information

The ball knobs GN 319.1 do not require a thread at the shaft.

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°).

The bore is conical which guarantees a firm press on operation.

The elastical polyamide bushing shows a good holding force even with a shaft tolerance of h11, the knobs are resistant to vibrations and may be re-assembled any time.
