Review this path for Humanoid fingers and thumbs, Robotic grippers and compact end effectors, Prosthetic and medical micro actuation where load density, stroke, and package length drive the screw architecture.
Finger-scale inverted roller screw solutions for robotic hands, grippers, prosthetics, and surgical end effectors.

Agree on backlash, backlash/preload, lead accuracy, and load-cycle evidence before sample approval.
Include the target actuator envelope, application duty cycle, quantity stage, and preferred inspection documents in the first inquiry.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Backlash | Project-specific low backlash or preload target | Crucial for delicate grasping, force feedback, and repeatable finger control. |
| Outer Diameter | Micro and miniature custom ranges | Controls whether the actuator can fit inside the finger rather than moving to a remote tendon drive. |
| Friction Torque | Measured during prototype validation | Small motors lose usable force quickly when screw friction is not controlled. |
| Repeatability Check | Cycle-test and fixture dependent | Gripper and finger mechanisms need stable motion after repeated short strokes, not only a good first movement. |
We can review packages around common micro motor families when you send the motor datasheet, allowable OD, stroke, force target, and bearing layout.
Load capacity is geometry-specific. For finger projects, share target pinch force, screw lever ratio, stroke, motor torque, and duty cycle so axial force can be reviewed realistically.
Hollow or wire-pass features can be reviewed when wall thickness, strength, bearing support, and cable-bend requirements are clear.
Noise depends on preload, surface finish, lubricant, speed, housing resonance, and motor control. We recommend measuring noise on the buyer-side fixture during sample validation.
