Stop Collars Are Threaded For Precise Stroke Adjustment

Adjustment of 'end of stroke' on shafts is usually a tedious procedure with regular shaft collars, according to Precision Pneumatics. To make it easier, the company is offering a new line of stop collars that are threaded to allow for precise stroke adjustment. Typical application is for robotic end-of-arm tooling in pick-and-place systems.

Fine-Adjust Stop Collars are threaded; to use them, simply slide the whole collar in place and tighten as you would an ordinary clamping shaft collar. Then rotate the knurled nut portion for extra-fine adjustment. The nut has a clamping screw of its own to lock in place.

These units are available in nine English and eight metric sizes and are designed to fit all brands of pneumatic linear actuator shafts and rods. Each size is available in stainless steel or steel with a black oxide finish.

English sizes are from 1/4 to 1-1/2 in. and metric from 6 to 30 mm (bore size). Prices range from $16.42 to $114.88.
