Harmonic Drive CSD-2UH Ultra-Flat Gear Units
Harmonic Drive CSD-2UH Ultra-Flat Gear Units
CSD-2UH is a housed ultra-flat strain-wave gear unit with an integrated cross-roller output bearing. It suits a rotary axis where axial length is constrained and a defined output support is valuable. The housed 2UH assembly is a different purchased scope from a CSD component set or the hollow-through-bore CSD-2UF construction.
Review Summary
Consider CSD-2UH when short axial packaging matters and the exact torque-duty and output-bearing limits fit the mechanism. Choose by a configuration-specific table, not a generic ultra-flat headline. A compact reducer still requires a compatible motor interface, adequate mounting stiffness and a complete load-path calculation.
