Recirculating roller screws (RRS) are an alternative to standard roller screws, designed for applications requiring compact dimensions, long strokes and high load capacity. Thanks to the internal recirculation of rollers within the nut, they ensure efficient operation even with smaller leads.
This configuration offers a balanced combination of load capacity, precision and low driving torque, making it suitable for demanding industrial applications within reduced space envelopes.
Key features
- Recirculating roller system
- Suitable for long strokes and small leads
- Balanced performance between load capacity and precision
- Reduced driving torque
- Available with cylindrical or flanged nuts
- Standard and custom solutions on request
