Product families for compact cycloidal reducer sourcing, from micro reducers to hollow-shaft, low-backlash, and custom OEM gearbox programs.
Use this page as a pre-RFQ navigator: pick the product family, capture the correct engineering inputs, and move directly to sample validation criteria that buyers can approve.
CAD / STEP Fast Paths
Buyers from the market-research plan usually arrive with an actuator envelope, not a finished part number. These paths send them to the relevant product family and its structured CAD / STEP request form.
Ultra-micro CAD route
Use when OD is under 30 mm and package tolerance matters more than generic catalog torque.
Include before CAD release
Target OD, axial length, output interface, ratio, micro-motion duty, and requested file type.
Humanoid joint CAD route
Use when shock margin, compact torque density, and low-backlash qualification drive the reducer choice.
Include before CAD release
Axis, OD class, rated and peak torque, ratio, backlash target, motor stack, and sample quantity.
Hollow-shaft CAD route
Use when the reducer, through-bore, output support, bolt circle, and cable bend radius must be reviewed together.
Include before CAD release
Bore target, flange height, output bolt pattern, cable route, ratio, torque, and envelope drawing.
| Product Family | Best-Fit Decision Rule | Quote Readiness Check | Next Step |
|---|---|---|---|
| Ultra-Micro Cycloidal Reducer | Best for robotics and medical-device engineering teams trying to keep torque, backlash, and package size inside very small mechanisms. Use this path when envelope class (OD <30 mm, including selected 12-15 mm concepts) is more important than starting from a generic gearbox size. | Ultra-micro projects fail early when reducer size is chosen after the surrounding joint envelope is fixed. Include target od, axial length, and output interface drawing in the first RFQ packet. | Review Ultra-Micro Cycloidal Reducer Request CAD / STEP pack |
| Compact Humanoid Cycloidal Reducer | Best for robot OEMs evaluating compact high-shock alternatives to harmonic drives in actuator-level joint designs. Use this path when outer diameter class (OD 30-80 mm robotics joint path) is more important than starting from a generic gearbox size. | Humanoid and quadruped joints are usually envelope-limited before they are catalog-limited. Include robot type, joint axis, payload, and torque profile in the first RFQ packet. | Review Compact Humanoid Cycloidal Reducer Request CAD / STEP pack |
| Micro Cycloidal Reducer | Best for OEM teams replacing bulky gearheads in tight envelopes. Use this path when ratio range (Project-dependent custom range) is more important than starting from a generic gearbox size. | Ratio determines output speed, torque multiplication, and package size. Include reduction ratio and target output speed in the first RFQ packet. | Review Micro Cycloidal Reducer Request CAD / STEP pack |
| Compact Cycloidal Gearbox | Best for machine builders that need a compact reducer sourced by specification. Use this path when rated torque (Matched by size and duty cycle) is more important than starting from a generic gearbox size. | Correct continuous torque avoids thermal overload and premature wear. Include target ratio and input speed range in the first RFQ packet. | Review Compact Cycloidal Gearbox Request CAD / STEP pack |
| Hollow Shaft Cycloidal Reducer | Best for buyers that need reduction and through-routing in one compact package. Use this path when hollow bore (Sized by cable route and torque class) is more important than starting from a generic gearbox size. | Bore size strongly affects reducer diameter, stiffness, and cost. Include required hollow bore diameter in the first RFQ packet. | Review Hollow Shaft Cycloidal Reducer Request CAD / STEP pack |
| Low Backlash Cycloidal Drive | Best for engineers comparing cycloidal, harmonic, and planetary reducer tradeoffs. Use this path when backlash target (Application-specific precision grade) is more important than starting from a generic gearbox size. | Backlash is the key sourcing filter for precision positioning projects. Include backlash target and measurement method in the first RFQ packet. | Review Low Backlash Cycloidal Drive Request CAD / STEP pack |
| Custom Cycloidal Reducer | Best for OEM buyers with drawings, target specs, and a defined production plan. Use this path when customization scope (Interface-only to full reducer package) is more important than starting from a generic gearbox size. | Scope defines engineering workload, tooling risk, and sample timeline. Include existing drawing pack or target envelope in the first RFQ packet. | Review Custom Cycloidal Reducer Request CAD / STEP pack |
| Flat Cycloidal Reducer | Best for equipment designers struggling with axial length constraints in their drive train. Use this path when axial length (Application-specific ultra-slim profiles) is more important than starting from a generic gearbox size. | Minimizing axial length allows more compact machine design or larger battery space in AGVs. Include maximum allowable axial length in the first RFQ packet. | Review Flat Cycloidal Reducer Request CAD / STEP pack |
| Cycloidal Drive Components | Best for advanced machine builders who want to eliminate the gearbox housing and mount gears directly into their frame. Use this path when integration depth (Component-level supply (disc, pin wheel, shaft)) is more important than starting from a generic gearbox size. | Component-level integration saves weight and space but shifts housing machining responsibility to the buyer. Include target ratio, peak torque, and backlash in the first RFQ packet. | Review Cycloidal Drive Components Request CAD / STEP pack |
