Rotary Counters for Machine Screwjack Actuators
Economical and easy mounting rotary counter with clockwise or anti clockwise models available.
RC-4145
The Duff-Norton Rotary Counter is for actuator customers who are looking for a more economical and easy way to determine an actuator’s position.
Our counters have been designed to match our most common actuator ratios.
An operator viewing the reading in the display window will know his actuator’sexact position because the counter’s display shows stroke to the nearest 1000ths of an inch up to 99 inches of travel.
Custom numeric displays are also available.
Features
- Display readings have been pre-matched to the actuator’s ratios.
- Display reading has been extended to the nearest 1000ths of an inch.
- Clockwise and counter clockwise models available.
- Easy mounting kits available for installation to existing field actuators.
Mounting Information
The Duff-Norton Rotary Counter fits over the actuator’s worm shaft.
A special worm bushing fills dimensional difference between the counters’ bore and the worms’ diameter (see table).
An anti-rotation pin from the counter’s rear into the actautors’ worm flange holds the counter steady.
