CD / CDH Compact Cup-Type Harmonic Reducers
CD / CDH Compact Cup-Type Harmonic Reducers
Compact cup-type harmonic reducers for thin installation spaces and integrated servo mechanisms where axial length is limited.
Product Highlights
- Thin cup-type layout for space-constrained precision transmission.
- Suitable for compact servo modules, inspection equipment and light robotic axes.
- CDH allowable load reference follows the compact cup-type reducer table in the product manual.
- OEM interface and motor flange adaptation are available for project orders.

Selection Checklist
- Required output torque: rated torque, peak torque and duty cycle.
- Reduction ratio and input speed range.
- Backlash or transmission accuracy requirement.
- Motor flange, input shaft, output interface and available installation space.
- Operating temperature, lubrication condition, mounting direction and expected life target.
- CAD/PDF drawings can be prepared according to selected model and customer interface requirement.
MOQ, Samples and Delivery
MOQ can start from 1 piece for sample or project validation. Typical delivery time is 15-50 days depending on model, quantity, customization and stock status. OEM motor flange and interface adaptation are supported.
