The popular HPN Harmonic Planetary value series from Harmonic Drive LLC is now available in a right angle configuration. The HPN-RA provides a low cost solution without the need to compromise on quality or performance. 

The HPN-RA Series features helical gears for High–Torque, quiet performance and long life. Backlash of <6 arc minutes (for single stage) is maintained for the life of the gear. Large radial ball bearings support the output shaft for high load capacity. HPN-RA Harmonic Planetary® gears are available with a smooth output shaft or a shaft with a key and tapped center hole. 

The HPN-RA gearheads are available with short lead times and are designed to couple to any servo or stepper motor with our Quick Connect mounting system.
