Description

- Precision brass collars of 3 types
- Tolerances better than tightest industry standards
Ultra-Fine Adjustment Screws 870-0080 are compact and provide extremely high resolution. Special design provides a smooth and repeatable action by mating a high precision 0.25 pitch stainless steel screw with a high precision brass collar. The screws have either a hardened steel ball on the top or a blunt ground tip.
The mounting surface of collar is either plain cylindrical or with a thread. The collars are ideally suitable for all mechanical stages and elements. The handy dimensions of the knobs are optimally chosen for fingers to rotate a knob with 0.5°-1° resolution. This enables to achieve 0.5 µm positioning sensitivity. The knobs are made of hard aluminium and come in various colours: black, white, red, green, yellow, blue, etc. By default the knobs are in black or white colour, 5 mm thick.
Ordering information:
Knobs come in 5 mm (standard), 10 mm or 15 mm length. When ordering, please append the standard screw code with the desired value for the length of the knob.
For example:
870-0080-A nominal travel 7 mm, ball tip, standard 5 mm lenght knob.
870-0080-D2-K10 nominal travel 7 mm, blunt tip, 10 mm lenght knob.
870-0080-F4-K15 nominal travel 25 mm, blunt tip, 15 mm lenght knob.
