ABB 3HAC044841-003 is a reduction gear rv-320e3 i=201 for IRB 6700. It performs axis-3 gearbox, ABB orange and must match the documented ABB configuration.
This colour-specific reduction gear is used where the documented ABB robot assembly calls for the orange finish. Confirm the axis location and article revision.
Compare the gearbox housing, mounting pattern, ratio and arm configuration with the supplied unit. Colour alone is not a compatibility check.
Secure the robot axis before removal, follow the applicable mechanical service procedure and verify motion, noise and backlash after installation.
Engineering check: Confirm 3HAC044841-003 is the RV-320E3 gearbox with 201 ratio for IRB 6700 axis 3 and the ABB orange execution. Compare flange, output orientation, sealing surfaces and attachment pattern before mounting.
Acceptance test: Use the ABB maintenance procedure for lubricant and filling position, then jog the affected axis at reduced speed. Check direction, backlash, noise, leakage and temperature, and update calibration or the revolution counter before production.
