Harmonic reducers for compact robot joints

Industrial robot joints need controlled motion in a limited installation space. Harmonic, or strain-wave, reducers combine a compact transmission layout with low-backlash motion, making them a useful option when positioning performance, size and moving mass matter.

Recommended model: ANDANTEX CS25 Harmonic Reducer

ANDANTEX recommends evaluating the CS25 for suitable robot joint applications. Match the exact configuration to joint torque, speed, reduction ratio, stiffness and the motor interface. The selected reducer must support the full operating cycle, including acceleration and peak loads.

Typical application scenarios

Collaborative robots: compact joint assemblies where installation space and moving mass are important design constraints.
SCARA robots: rotary axes for repeatable assembly and pick-and-place motion, subject to cycle-time and load checks.
Six-axis articulated robots: suitable joints requiring compact reduction and controlled positioning. Each joint must be sized separately for its load and moment.

What determines positioning performance?

Gear backlash is only one part of joint performance. Torsional deflection, lost motion, bearing stiffness, encoder feedback and control tuning also affect the result. Confirm the CS25 specifications for the selected configuration rather than treating zero backlash as a guarantee of zero positioning error.
