Who this fits
For robotics teams that need custom hand actuation with clear CAD envelopes, force/stroke targets, tendon or pushrod routing, and life-test expectations, not consumer-grade hobby servos.
Custom micro actuator development for humanoid fingers, thumb mechanisms, tendon drives, Bowden tube layouts, pushrod modules, and compact end-effectors where sub-16 mm class packaging, force, stroke, sensing, cable life, and thermal margin must be solved together.
This page should help a robotics buyer decide whether this product family belongs in the RFQ path and what evidence must be attached before a prototype or pilot order is credible.

Sub-16 mm class package fit: Finger geometry and mechanism dependent
A micro actuator meets no-load speed but overheats or stalls under real fingertip force
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Sub-16 mm class package fit | Finger geometry and mechanism dependent | Dexterous hands often fail at the envelope level before torque calculations matter because motor, gearbox, sensor, cable, and housing cannot all occupy the finger volume. |
| Force and stroke fit | Linkage, tendon, or pushrod dependent | Hand actuators often fail because a promising motor cannot deliver the required fingertip force across the real linkage stroke. |
| Thermal margin | Duty cycle and stall dependent | Small sealed actuators have limited heat path, so continuous grasping or repeated stalls must be reviewed before sample build. |
| Tendon, cable, and sensor durability | Routing, bend radius, strain relief, and cycle dependent | Finger mechanisms can pass early motion tests but fail when Dyneema tendons, Bowden tubes, flex cables, leads, or sensors are not protected for repeated cycles. |
Product selection is only useful when it connects to a buyer-visible evidence path. These proof gates turn the page from a capability description into an RFQ checklist.
| Proof Gate | Evidence to Ask For |
|---|---|
| Drawing baseline | CAD package, controlled drawing revision, CTQ list, open trade-offs, NRE scope, and prototype/pilot responsibility. |
| RFQ evidence package | Buyer-side package with joint map, CAD/drawing baseline, torque-speed or force-stroke targets, validation request, pilot quantity, and report expectations. |
| Evidence library | Stage-by-stage map for CMM, FAI, actuator validation, electronics/FCT, traceability, NCR, packaging, and pilot release records. |
| Test plan checklist | Operating cycle, fixture boundary, torque-speed or force-stroke method, thermal-rise setup, backlash method, FCT, endurance, and report handoff. |
| Sample PO checklist | Drawing revision, CTQ acceptance limits, report deliverables, sample variants, buyer-supplied boundaries, change rules, packaging, and delivery records. |
| Manufacturing proof | FAI, CMM, datum checks, bearing fit, flange flatness, output runout, surface treatment, and outgoing reports. |
| Actuator validation | Torque-speed, thermal rise, backlash, noise, FCT, burn-in, traceability, nonconformance, and pilot release records. |
| BOM and sourcing control | Approved parts, restricted suppliers, substitutions, lead time, firmware boundary, harness, packaging, and second-source risk. |
A serious custom actuator inquiry should show how the selected product family moves from feasibility review into repeatable pilot manufacturing.
Review CAD, joint load, envelope, thermal boundary, cable path, and custom actuator architecture risk.
Build the first sample against defined torque-speed, fit, electrical, mechanical, and inspection assumptions.
Run thermal, backlash, noise, endurance, impact, metrology, and functional checks against the application duty cycle.
Freeze drawing/BOM revisions, evidence package, outgoing inspection, packaging, spare strategy, and repeat-build controls.
This form is prefilled with Dexterous Hand Micro Actuators. Add CAD envelope, torque-speed target, duty cycle, validation needs, quantity, and schedule so the response can start with DFM questions instead of generic sample pricing.
Yes, when the project includes a mechanical envelope, target force or torque, stroke or angle, duty cycle, and expected cycle-life requirement for the hand mechanism.
The focus is custom actuator and integration support. A full hand assembly can be discussed when the customer provides the hand architecture, interface responsibility, and validation plan.
Yes. Send the finger envelope, force and stroke target, selected motor or gearbox if any, tendon or Bowden routing, sensor requirement, stall condition, and expected cycle-life evidence.
