RFQ Checklist
- Send incumbent RV model number (e.g., RV-110E, RV-320C)
- State required ratio, application torque, and external moment load
- Confirm input motor shaft dimensions for the sun gear adapter
- Define delivery timeline for prototype validation
Cycloidal pinwheel and planetary RV reducers for heavy industrial robots, offering immense shock load resistance, high torsional rigidity, and true drop-in compatibility.

| Metric | Typical Range | Why It Matters |
|---|---|---|
| Shock Load Capacity | Up to 500% of nominal torque | Industrial robots frequently experience emergency stops and collisions; the RV pinwheel mechanism prevents catastrophic failure. |
| Torsional Stiffness | High rigidity across the full torque spectrum | Prevents end-effector vibration and settling time delays in heavy-payload operations. |
Public Selection Matrix
Use this matrix to identify the right engineering review path before requesting model-specific CAD, drawings, or a drop-in replacement check.
| Subseries | Scope | Public Specs to Check | Buyer Use |
|---|---|---|---|
| Cycloidal pinwheel RV reducer | Classic RV-style cycloidal pinwheel reducers for robot joints, positioners, and high-shock automation axes. |
| Use this family when robot-axis stiffness and impact capacity are more important than lowest cost. |
| Planetary gear type RV reducer | RV packages with planetary input distribution for compact servo matching and smooth torque transfer. |
| Use this family for robot arm axes where motor integration and package length are key constraints. |
| Bearing type RV reducer | RV reducers with integrated output bearing support for moment loads and direct robot-joint mounting. |
| Use this family when the reducer also carries the axis output load. |

STEP, IGES, SolidWorks, 2D PDF on request
Use the no-login worksheets before sending drawings or requesting model-specific CAD. They help engineering confirm torque, backlash, interface, inspection, and replacement assumptions for Heavy-Duty RV Speed Reducers.



Yes, our RV series provides 100% mechanical and performance interchangeability for both solid (E-series) and hollow (C-series) types.
Yes, our hollow-bore RV reducers allow power and data cables to pass directly through the center axis, identical to incumbent designs.
