Sample-ready shortlist
We help turn a joint request into a sample shortlist with torque class, protocol, brake/encoder assumptions, supplier notes, and known integration questions.
Programmable joints
Find programmable joint modules that your engineering team can actually integrate.
Tell us the torque, speed, voltage, protocol, size limit, brake/encoder needs, and quantity. We help compare China-sourced integrated joints and actuator modules by fit, sample route, documentation risk, and production readiness.
- Core buyer
- robot builders / labs
- Must compare
- rated torque vs peak
- Common protocols
- EtherCAT / CAN / RS485
What you get
A practical sourcing answer, not a generic catalog link.
Datasheet comparison
A good comparison goes beyond price: rated torque, peak torque, backlash, speed, heat, voltage, protocol, software tools, firmware support, and cable routing matter.
Production risk notes
Before moving from prototype to batch, we check documentation quality, sample availability, lead time, MOQ, supplier continuity, and long-term support expectations.
Buying checklist
Send these specs to get useful options.
Most bad robot quotes start with missing application details. These fields let us compare suppliers by fit, not only by price.
- Module types
- Integrated joints, harmonic actuators, servo actuator modules
- Common signals
- Rated torque, peak torque, speed, voltage, protocol
- Applications
- Prototype arms, mobile manipulators, lab robots, equipment axes
- What you receive
- Module class, supplier-fit notes, sample and risk checklist
- Rated torque, peak torque, target speed, and duty cycle
- Voltage, communication protocol, and controller stack
- Outer diameter, length, mounting, and hollow-shaft requirement
- Brake, encoder, backlash, reducer type, and cable routing needs
- Prototype quantity, production estimate, target cost, and timeline
Common buyer requests
When it makes sense to contact us.
A robotics startup needs joint samples for a 6-DOF prototype arm.
A lab or mobile robotics team needs compact actuators with a specific control protocol.
An equipment maker wants a China alternative to high-cost imported actuator modules.
A builder needs to understand whether the supplier's documents and firmware are good enough before ordering samples.
FAQ
Questions buyers usually ask before sending specs.
Is a programmable joint the same as a robot arm?
No. A programmable joint is a component or module used to build a robot arm or motion axis. A robot arm is the assembled machine with controller, links, wiring, and safety requirements.
Which details matter most for sourcing a joint module?
Rated torque, peak torque, speed, backlash, encoder, brake, voltage, protocol, size, thermal behavior, documentation, firmware support, sample availability, and supply stability are the core fields.
Who is this product line best for?
It is best for robot builders, hardware startups, labs, equipment makers, and integrators with engineering capability.
Before you buy
We help check the sourcing risks before money is spent.
- End-effector weight and real payload margin
- Controller, protocol, and documentation quality
- Warranty, spare parts, MOQ, lead time, and payment terms
- Local integration, safety, installation, and support scope
Next step
Send the requirement you already have.
We can start from partial specs and reply with the missing questions, likely option direction, and next sourcing steps.
