Product description
Ball knobs EN 319.1 do not require a thread on 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 polyamide bushing provides a good holding force even with a shaft tolerance of h11. The knobs are resistant to vibrations and may be re-assembled any time.
