Harmonic Drive HPG-RA Right-Angle Planetary Gearheads
HPG-RA is a right-angle planetary gearhead with a load-supporting cross-roller output bearing and motor-mounting options. It belongs to Harmonic Drive’s planetary range, rather than its strain-wave component sets. Three frame sizes, configuration-specific reduction ratios and distinct output styles let a designer redirect the motor axis while keeping the load close to a supported output.

Review Summary
Consider HPG-RA for an automation axis that needs a right-angle motor arrangement, low planetary backlash and substantial output-load support. Size it from the full torque-duty and bearing-load requirements. The 150–2200 Nm family headline describes repeated peak torque across different configurations; it does not describe continuous torque or a single gearbox covering the entire range.
