Mechanical Position Indicators
Tracking your machine component as it moves along a rotating threaded shaft, such as a spindle or lead screw, these indicators help you adjust machinery with speed and precision. They save time and prevent errors on process lines that you constantly adapt to suit different products, such as packaging lines.
Use the display number as either a reference point or as a true measure of distance. To measure distance, match the indicator’s count per revolution to your lead screw’s threads per inch or thread pitch.
Choose between indicators that count up when your lead screw rotates clockwise or counterclockwise.
Add shaft locking clamps to keep indicators in place and prevent vibration from shifting them.
Add shaft reducer bushings to adapt indicators to fit small diameter shafts. Stainless steel bushings are more corrosion resistant than black-oxide steel bushings, so they’re better in humid locations.
