Product Overview
The CSF-1U-CC-F miniature gear unit features a flange output and is designed for motor mounting via an adapter plate. Available in frame sizes 5 to 14mm with outer diameter 21mm to 52mm and mass 25g to 295g. Gear ratios 30 to 100 with momentary peak torque 0.9 to 54 Nm.
The CSF-1U-CC-F is a precision zero-backlash gear unit designed for compact motion systems requiring high torque density, repeatable positioning, and simplified mechanical integration.
Precision Gear Unit Architecture
Harmonic Drive gear units deliver zero backlash, high torque density, and exceptional positioning accuracy in a complete housed assembly. The cross roller output bearing directly supports loads without additional bearings, simplifying mechanical design and reducing system cost.
Zero Backlash
Strain wave gear principle eliminates all backlash for bidirectional positioning without dead band.
High Torque Density
Compact housing delivers high repeated peak torque relative to size and weight.
Cross Roller Output
Integrated cross roller bearing supports radial, axial, and moment loads directly.
High Accuracy
Standard accuracy less than 1 arc-min across the full range of available sizes.
High Stiffness
Torsional stiffness K1/K2/K3 data available for all sizes for system compliance analysis.
Compact Housed Assembly
Complete housed gear unit reduces external support hardware and simplifies mechanical integration.
Typical Applications
The CSF-1U-CC-F suits robot joint axes, rotary index tables, semiconductor wafer handling stages, machine tool rotary axes, precision gantry drives, and any application requiring zero backlash speed reduction with direct load attachment.
