Inverted roller screws (IRS) feature a design opposite to standard roller screws, where the rollers do not move along the shaft and the motion occurs within the nut. This configuration enables a more compact design and optimized motion transmission.
Thanks to the possibility of using smaller leads and a rotating nut configuration, IRS screws are particularly suitable for applications requiring compact layouts and precise motion control.
Key features
- Inverted roller configuration
- Motion within the nut
- Suitable for rotating nut designs
- High system compactness
- Available in various leads and sizes
- Standard and custom solutions on request
