Roller screws
Benefits
- Most compact solution for high force linear motion
- Best in class reliability and lifetime
- Low operating noise, high speed, and acceleration capability
- Easily customized design for easy integration
Features
- Planetary type for highest speed (N.d0 max = 160,000) and load capacity
- Inverted planetary type for compactness, direct drive, and easy sealing
- Recirculating type for highest resolution (down to 1 mm lead) and stiffness
- Backlash-free or preloaded execution on request
Thanks to their high precision and rigidity, roller screws are the ideal choice for heavy loads, long duty cycles, high speeds, high accelerations, and harsh operating conditions.
