Procurement Guide: Key Decisions
Before you buy a roller screw actuator, understand the non-negotiable requirements that make it a worthwhile investment over traditional ball screws or hydraulic cylinders.
15x Longer Life
Planetary roller screws provide up to 15 times the fatigue life of equivalent ball screws. If your application doesn't require high cycles, you may be overspending.
Upfront Cost vs ROI
Expect to pay 2-4x more upfront compared to ball screws. The ROI is realized in reduced maintenance, zero hydraulic leaks, and eliminated downtime.
Custom vs Standard
Standard COTS models ship in 4-8 weeks. Custom coatings, non-standard strokes, or IP69K washdown prep pushes lead times to 12+ weeks.
When to Buy a Roller Screw Actuator
- Replacing HydraulicsYou need to eliminate fluid leaks, reduce noise, and improve positional control without losing force density.
- High Shock LoadsPresses, riveting, and stamping applications where ball screws experience premature brinelling.
- Continuous Duty CycleApplications running 24/7 (80-100% duty cycle) where thermal capacity and fatigue life are critical.
When NOT to Buy
- Light Duty Pick & PlaceLow load, high-speed applications (< 5 kN) are better served by pneumatic cylinders or belt drives.
- Strict Budget ConstraintsIf upfront CapEx is strictly capped and long-term maintenance isn't your department's cost, ball screws win on initial price.
- Extremely High SpeedsLinear speeds exceeding 1.5 m/s generally exceed the thermal capacity of roller screws without active cooling.
Lifecycle Cost Comparison (10-Year Horizon)
Note: Roller screw actuators require a higher upfront investment (CapEx) but maintain a flat operational cost over their lifespan due to high fatigue life and zero fluid maintenance.
Frequently Asked Procurement Questions
What is the standard price range?
Prices vary wildly based on stroke, size, and motor integration. A small base unit might start around $3,000 - $5,000, while high-capacity 500kN units can exceed $20,000. This is 2-4x higher than an equivalent ball screw actuator.
Can I buy just the roller screw mechanism?
Yes, but most buyers procure a complete actuator assembly (screw, thrust tube, bearings, housing). Buying just the bare screw requires high-precision integration on your end, which often voids system-level warranties.
How do I specify the motor mount?
We provide inline and parallel (belt-driven) mounts for major servo brands (Yaskawa, Allen Bradley, Beckhoff, Siemens). When requesting a quote, specify your intended servo motor model, and the flange will be matched.
