| Metric | Typical Range | Why It Matters |
|---|---|---|
| Thrust Force | Project-sized from load/life inputs | High force alone is not enough; equivalent load, stroke, speed, and duty cycle determine practical screw size. |
| Duty Cycle | High-cycle industrial motion | Servo presses and molding equipment need load life, heat, and lubrication checks before approval. |
| Inspection Focus | Lead, hardness, roughness, preload, torque | Protects heavy-duty buyers from early wear after hydraulic replacement. |
| Best Fit | Open-axis or electric-cylinder layouts | Standard planetary architecture is usually better than inverted architecture when axial length is not the main constraint. |
In many machines, yes, but replacement should be reviewed against peak force, duty cycle, heat, shock load, package length, and safety requirements rather than thrust alone.
Roller screws can offer much longer life in high-load service because load is distributed across multiple rolling contacts. The actual life estimate depends on dynamic load rating, equivalent mean load, speed, lubrication, and alignment.
Planetary roller screws are well suited to shock-load applications, but we still review impact factor, material, heat treatment, preload, mounting stiffness, and validation evidence before approval.
High-speed feasibility is reviewed by lead, RPM, lubrication, heat, bearing support, and duty cycle. Speed targets should be supplied together with load and stroke data.
