Roller Screw Drives

Service-grade precision. Industrial-grade power.
Roller screw drives combine the precision of measurement systems with the strength of heavy-duty actuation. Instead of balls, they use multi-groove rollers that travel along the screw thread like satellites in a planetary gear system.
The result? A stable, smooth drive with extremely high load capacity, ready for 24/7 operation in the most demanding applications.

Why it matters

Higher load capacity and longer service life – A larger contact area between rollers and thread reduces surface pressure and wear, resulting in a long, predictable service lifespan.
Precision in linear motion – Minimal axial backlash and excellent positional repeatability make it easier to achieve micrometer-level tolerances.
Efficiency and refined performance – Rolling contact minimizes friction, noise, and heat generation; the system runs smoothly even at high feed rates.
Compact under high loads – High power density enables drive size reduction without compromising performance.
Low Total Cost of Ownership (TCO) – Less frequent maintenance, longer lubrication intervals, and reduced downtime result in significant savings over the machine’s life cycle.

Ideal applications

Automation and robotics – Linear axes requiring high dynamics and stiffness.
Presses and metal forming – Precise positioning under high force conditions.
CNC machinery – Stable accuracy in heavy-duty machining environments.
Aerospace, space, and energy – Systems where reliability and safety are mission-critical.
Medical and testing equipment – Controlled motion, high repeatability, and cleaner operation.

How it works – in short

The roller assembly orbits the screw core along a specially profiled thread. Each roller carries a portion of the load, with movement guided by an internal recirculation system.
The distribution of force across multiple contact points reduces wear, minimizes backlash, and maintains long-term precision.

Advantages over ball screws

• Larger load-bearing surface → Higher dynamic and static load capacity.
• Lower susceptibility to shocks and overloads → Stable operation in impact-intensive cycles.
• Improved backlash control → Factory preload possible without compromising smoothness.
• More durable thread geometry → Lower risk of raceway deformation and accuracy loss.
