Only 8mm Thin – Purpose‑Built for Robot Joint Rotary Actuators
Rotary actuators in humanoid robots (shoulders, elbows, wrists) must lock instantly upon power loss or emergency stop to prevent unintended joint rotation, while releasing quickly when powered to maintain smooth motion. Conventional brakes, however, typically exceed 15mm in thickness—significantly crowding joint axial space, increasing overall length and weight, and restricting biomimetic design.
Our Ultra‑Thin Spring‑Applied Brake, with a minimum thickness of just 8mm, delivers an extremely compact braking solution for rotary actuators—reliable holding within limited space, without compromising torque or response speed.
Compared to conventional spring brakes (typically >15mm thick), our product achieves nearly 50% thickness reduction. For a humanoid robot with 15–20 braking joints, this translates into over 100mm of total axial length savings—freeing up valuable space for sleeker, more anthropomorphic designs.
Specifically engineered for robotic rotary joints that demand high‑frequency start‑stop and bidirectional rotation, the brake features optimized response time, release delay, and wear resistance—ensuring reliable performance under high‑speed rotation and frequent braking.
Through structural optimization and lightweight materials, we achieve minimal weight without sacrificing braking torque. Lower joint inertia translates into quicker start‑stop response, reduced energy consumption, and extended battery life.
Designed with spring‑applied braking, electrically released (fail‑safe) mechanism, the brake automatically locks upon unexpected power loss—eliminating joint runaway risk, a core safety requirement for humanoid robots.
Optimized friction materials and braking surfaces ensure low acoustic noise, suitable for quiet service robot environments. Braking pads are durability‑reinforced, supporting hundreds of thousands of cycles with extended maintenance‑free intervals.
| Joint Application | Key Value |
|---|---|
| Shoulder rotation | Ultra‑thin design saves axial space, enabling more natural shoulder contouring |
| Elbow joint | Lightweight construction reduces arm inertia for faster, more agile grasping |
| Wrist rotation | Slim profile frees up precious wrist space for force sensor integration |
| Waist rotation | Reliable locking prevents torso tilt during standby |
Axial space savings: Thickness reduced from 15mm+ to 8mm – more compact joints, slimmer overall robot
Weight reduction: Tens of grams saved per joint – cumulative effect significantly improves energy efficiency
Simplified assembly: Standardized mounting interface – quick installation without complex adjustments
Enhanced safety: Fail‑safe power‑off locking meets humanoid robot safety standards
Every humanoid robot has unique spatial and load requirements. We offer flexible customization options:
Thickness: Adjustable within 8–15 mm range
Torque: Tailored to your joint load demands
Mounting interface: Customized to fit different actuator flanges
Voltage: Multiple voltage options available
From selection to mass production, we provide full technical support to accelerate your product development.
