Adjustment knob drilled grooved

With this adjustable knob GN 700 a shaft can be infinitely adjusted in both directions. The anti-backlash mechanism with a max. load of 15 Nm ensures the firm locking of the shaft in any position. This mechanism prevents any uncontrolled movement of the shaft. The locking action is a safety feature to prevent unwanted re-adjustments caused by backlash and vibration. Scale and arrow on the control knobs are indelibly marked and easily legible since the engraved "aluminum colored" numbers contrast with the black anodized surface. Besides the standard scale (type S) the control knob version may be supplied with any other scale (type KS). Regarding design, numbering run, numbering position and numbering sequence of the scale please see the layout for scale rings on the order sheet „How to order Graduations“
