Roller screw drives meet the demands that ball screws can no longer handle. The load is transmitted from the screw shaft to the nut via the convex thread flanks of the rollers. The number and surface area of the contact zones are increased. Therefore, roller screws provide significantly higher load capacity and longer service life than comparable ball screws.
- High load capacity (SR-SV)
- Very high rotational speed (SR)
- Rapid acceleration and deceleration (SR)
- Long service life even under fast cycle changes (SR)
- High reliability (SR-SV)
- Suitable for harsh environmental conditions (SR)
- Absorption of shock loads (SR)
- Short stroke lengths with excellent repeatability (SV)
- Driving the screw nut at critical speeds (SR)
- Easy removal of the nut from the screw shaft (SR, most SV)
