The exclusive Helicoid® cam and roller movement reduces wear problems associated with with conventional gear movement, thus increasing service life and maintenance of accuracy. The rolling action of the cam facing against the the highly polished stainless steel roller produces minimal friction and wear. The unique back adjust screw provides readily accessible external zero adjustment for most applications. User experience has proven that Helicoid's cam and roller movement dramatically increases gauge life - up to ten times over conventional geared movements. This is especially true in applications where the gauge is subjected to severe pressure pulsations or mechanical vibration.
