ABB RV-500N 3HAC043073-001 is an RV-series reduction gear for an IRB 6700 robot joint. It receives drive from the assigned axis motor, reduces rotational speed and delivers the resulting torque through the robot arm interface.
Mechanical accuracy of ABB RV-500N 3HAC043073-001 depends on the input coupling, output flange, bearing support and sealed lubricant volume working as one assembly. The RV-500N designation and complete 3HAC article identify the required execution; the family name alone is not sufficient for replacement.
When ABB RV-500N 3HAC043073-001 is replaced, the arm must remain restrained until the gearbox and motor are fully seated. Calibration and controlled low-speed travel then confirm joint direction, backlash, noise, seal integrity and position repeatability.
