Miniature inverted roller screw sets for robotic fingers, dexterous hands, surgical mechanisms, and compact precision modules.
Micro-robotics, dexterous hand, and medical device teams replacing miniature ball screws or custom lead screws.
High-load planetary roller screw assemblies for servo presses, hydraulic replacement axes, test rigs, and heavy industrial motion.
Machine builders and automation teams replacing hydraulic cylinders or undersized ball screws in high-force axes.
Compact electromechanical actuator architecture built around an inverted roller screw, frameless motor envelope, and push-tube integration.
Actuator OEMs and system integrators designing compact EMA modules around proprietary motor and housing constraints.
Drawing-based manufacturing for proprietary inverted roller screw shafts, long nuts, rollers, and compact actuator screw sets.
Engineering teams with proprietary actuator geometry rather than catalog part numbers.
Internally threaded nuts, screw shafts, rollers, timing rings, end machining, and assembly support for roller screw programs.
Actuator builders sourcing critical roller screw parts or validating a custom assembly supply chain.
| Product Family | Primary Buyer Focus | Key Metric | Why It Matters |
|---|---|---|---|
| Inverted Planetary Roller Screw | Robotics, aerospace, and compact EMA teams that need high thrust in a short linear package rather than a catalog ball screw. | Custom Diameter Window: Approx. 8-100 mm project-dependent | Defines whether the inverted layout can fit humanoid joints, compact EMA tubes, or heavier industrial axes. |
| Micro Inverted Roller Screw | Micro-robotics, dexterous hand, and medical device teams replacing miniature ball screws or custom lead screws. | Outer Diameter: Approx. 4-12 mm custom feasibility range | Crucial for multi-finger packaging where every millimeter changes motor and tendon layout. |
| Standard Planetary Roller Screw | Machine builders and automation teams replacing hydraulic cylinders or undersized ball screws in high-force axes. | 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. |
| Inverted Roller Screw Actuator | Actuator OEMs and system integrators designing compact EMA modules around proprietary motor and housing constraints. | System Efficiency: Up to 80% | Reduces battery drain in mobile/aerospace applications. |
| Custom Roller Screw Manufacturing | Engineering teams with proprietary actuator geometry rather than catalog part numbers. | DFM Turnaround: 2-5 business days after complete data | Reduces quote loops before machining custom screw geometry. |
| Precision Roller Screw Components | Actuator builders sourcing critical roller screw parts or validating a custom assembly supply chain. | Component Scope: Nut / shaft / roller / ring / assembled set | Lets buyers source only the precision component blocking their actuator program. |
Start with inverted architecture when the screw must fit inside a short motor, push-tube, or robot joint envelope.
Use micro screw paths when robotic fingers, grippers, and medical mechanisms need high force in a very small diameter.
Use custom manufacturing when your geometry, material, end machining, or inspection package cannot be handled by catalog sizes.
