Product Description


Inverted Roller Screw – Short Description

  • Principle: Same as standard planetary roller screws – rollers orbit between screw and nut, converting rotation to linear motion.

  • Drive: Input can be on the screw (screw+rollers move axially) or on the nut (nut translates).

  • Advantages: Ultra‑compact axial length, high load capacity, high rigidity, high speed & acceleration, low friction, fully customisable nut designs.

  • Sizes: Screw diameters Ø8–80 mm, multiple lead options, nuts made to order.
