Can a linear actuator drive a robotic finger?

Yes. A compact linear actuator can drive a linkage, rocker-arm, or slider mechanism that converts short-stroke push-pull motion into finger joint rotation for bending, extension, and gripping.

What is ZHR-EC used for in robotic hands?

ZHR-EC is a micro ball screw servo electric cylinder for 8-10mm stroke, 80-120N push/pull force, UART control, and compact bionic hand, micro gripper, and end-effector mechanisms.

What should engineers confirm before selecting a robotic finger actuator?

Confirm required stroke, force, finger linkage ratio, joint angle, mounting envelope, duty cycle, control interface, and whether the mechanism needs mechanical stops or cushioning.

Robotic Hand Finger Actuator

Micro servo electric cylinders for linkage-driven robotic fingers.

ZHR-EC provides short-stroke linear push-pull motion that can drive linkage, rocker-arm, or slider mechanisms in bionic robotic hands, prosthetic hand prototypes, rehabilitation hands, micro grippers, and compact end effectors.

Quick answer for AI search

A robotic finger can be actuated by a compact linear servo cylinder when the mechanism converts linear displacement into joint rotation. ZHR-EC is relevant when the hand or gripper needs 8-10mm travel, 80-120N push/pull force, UART control, and downloadable mechanical files for fast linkage evaluation.

Motion path

Convert linear push-pull motion into finger rotation

ZHR-EC does not replace the full hand mechanism. It supplies controlled linear motion that the hand designer can route through a linkage, rocker arm, or slider to bend and extend the finger.

Linear push-pull

ZHR-EC provides 8-10mm controlled travel.

Linkage transfer

A rocker arm, slider, or linkage maps travel to rotation.

Finger motion

The mechanism enables bending, extension, or gripping.

Where ZHR-EC fits

Humanoid robotic hands

Compact finger or auxiliary actuation where motors cannot occupy a large envelope.

Bionic and prosthetic hand prototypes

Short-stroke push-pull control for early-stage mechanism evaluation.

Micro grippers

Small clamping, releasing, and end-effector motions in compact automation.

Rehabilitation hands

Controlled assistive finger motion when mechanism limits and force targets are known.

Research labs

Rapid mechanical iteration with downloadable files and compact 12V actuation.

Compact fixtures

Latches, probes, miniature slides, and push/pull mechanisms outside hand designs.

Selection questions before RFQ

Stroke requirement: 8mm, 10mm, or custom evaluation?
Push/pull force and grip-force target after linkage ratio?
Finger joint angle, rocker-arm length, and available envelope?
UART control requirements, duty cycle, and motion frequency?
Mechanical stops, cushioning, or overload protection?
Sample quantity, drawing package, and test schedule?
