Rollvis RVI Inverted roller screws

Inverted designs typically have three starts. With fewer starts, the inverted design can use a larger thread form and, in turn, provide higher load capacity than a standard planetary design. Because the screw shaft of an inverted roller screw is only threaded for a section equal to the length of the rollers, the rest of the shaft can be customized, making inverted screws ideal for integration into systems such as linear actuators.
