EN 319.1 Ball Knobs Phenolic Plastic, Press-On Type


EN 319.1 Phenolic Plastic Ball Knobs, Press-On Type
ELESA original design
code: S.N

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.
