Harmonic Drive CSG-2A High-Torque Component Sets
Harmonic Drive CSG-2A High-Torque Component Sets
CSG-2A is a cup-type strain-wave gearing component set for a customer-designed rotary mechanism. It emphasizes higher torque capacity within the CSG family, while leaving the motor, housing and output-load support to the OEM. The related lightweight LW and big-bore BB-LW versions provide different packaging choices that must be selected by full ordering code.
Review Summary
Consider CSG-2A when the application benefits from high reduction and low backlash inside a custom mechanism, and the engineering team can control alignment, support and lubrication. A CSG-2A component set is not interchangeable in scope with a CSG-2UH housed gear unit. The big-bore lightweight option also requires an explicit overload comparison with the standard lightweight version.
