About This Part
When purchasing high torque rotary actuators, it is necessary to clarify its importance as the "power core" of the robot. The power bearing, dynamic response and operating stability of the Robot High Torque Rotary Actuator all rely on the output performance of KGL's high torque rotary actuators, which is the basis for achieving efficient operation of industrial automation. Whether it is industrial robots carrying heavy workpieces, collaborative robots working with people, or humanoid robots supporting their own weight and carrying objects, their joints all require KGL high-torque rotary actuators to provide sufficient torque; facing high-resistance tasks such as tightening bolts and pressing parts, or high-acceleration actions that pursue production rhythm, our KGL products can effectively overcome inertia and reduce vibration offset with high torque characteristics and rigid design, while achieving strong power output with high power density in a limited space. In terms of drive mode selection, the electric actuator solution promoted by KGL Machining is based on frameless torque motors combined with harmonics and planetary reducers. The high power density of permanent magnet synchronous motors and the zero backlash characteristics of reducers make them outstanding in large joint applications such as industrial robot bases and shoulders; for special scenarios, KGL also provid

Common Questions
Which materials can this part be machined from?
Common options include 6061/7075 aluminum, stainless steel, 45 steel and engineering plastics. Send your drawing and we confirm material availability and stock within 24 hours.
What tolerances can you hold?
Standard tolerance is ±0.005 mm on metals, engineering plastics, and carbon fiber composite. Every dimension is verified against the 3D model on Hexagon or Zeiss CMMs.
How fast can I get first samples?
You receive engineering feedback with the quotation, within 24 hours of sending a drawing. Prototype parts are typically machined in 15 to 25 days depending on geometry and finishing.
What quality documentation comes with the parts?
Each shipment can include a first-article inspection report, dimensional CMM report, and material certificates. KGL is certified to ISO 9001:2015, ISO 13485:2016 and AS9100D.
Is there a minimum order quantity?
No. KGL supports 1-piece prototypes through volume production on 100+ CNC machines, so you can start small and scale the same process.
