Save your time and energy in repositioning
with our unique Rapid Advance Feature. This feature is ideal
long travel UniSlides,
medium travel units with fine
any units that are frequently
How they work: Rapid Advance
models use a clutch-like design to uncouple the slider from
the drive mechanism. You quickly push the slider, by hand, where
you want it. Then, fine tune your position after re-engaging
the drive screw.
Long travel Series A15 Rapid Advance model with measured
Customer requested a Rapid Advance Model D. They wanted
to measure the travel but only needed a resolution of
1 mm. The solution is a metric lithographed scale graduated
in 1 mm increments added to the standard Model D. Note
the optional extra length slider with hash mark.
Another idea: Screw Drive UniSlide with a coarse lead screw
When you spec a 2.5 turns per inch lead screw in the standard Screw Drive type UniSlide, you can push the slider along for rapid translation (movement). Watch this video:
Advantages of 2.5 turns screw:
-Less expensive, complex and higher load capacity than Rapid Advance UniSlides
-reduced sensitivity for tiny increments of motion
-2.5 and 5 pitch are not self-locking. Will fall if in a vertical position or move if thrust load is in direction of travel. We highly recommend use of locking screw to hold position.
