Plateau diviseur à came globoïdale Rollerdex DSA/DS series
SANKYO
While the linear system uses ball screws, Sankyo uses a roller gear for rotary systems to successfully get performance equivalent to a linear system. As with ball screws, the roller gear cam mechanism, consisting of this roller gear and a globoidal cam, can provide a preload design without backlash. The rolling contact surfaces make it highly rigid and efficient. Of course, no clamping device is necessary.
