ABB 3HAC021204-001 is a balancing device for the IRB 6650S, while ABB 3HAC021353-001 is a Yaskawa motor unit for axis 4 on the IRB 2400/10 and IRB 2400/16. The articles represent different robots and different mechanical functions.
The ABB 3HAC021204-001 balancing device supports the arm-load relationship and must be handled with the prescribed press and support procedure. ABB 3HAC021353-001 mounts with the axes 4–6 motor group on the back of the IRB 2400 upper arm and must remain matched to the Yaskawa execution.
When selecting ABB 3HAC021204-001 or ABB 3HAC021353-001, use robot variant, installed article and service position. The IRB 2400 manual explicitly warns that different motor executions are not compatible, so the axis-4 motor cannot be selected from location alone.

ABB 3HAC021204-001 and ABB 3HAC021353-001 require separate support methods, but both demand positive control of robot movement before fasteners are released.
For 3HAC021204-001, secure the IRB 6650S arm and use the documented press/support method for the balancing device.
Before fitting 3HAC021353-001, verify the IRB 2400 Yaskawa axis-4 configuration and preserve connector identity.
After reassembly, check the balancing path or axis-4 drive at low speed before releasing the robot for normal cycles.
ABB 3HAC021204-001 and ABB 3HAC021353-001 connect mechanical assemblies back into different robot-control paths.
3HAC021204-001 must restore the intended arm counterbalance relationship without binding or unverified preload.
3HAC021353-001 must reconnect motor power, brake and feedback to the documented axis-4 channel.
After mechanical verification, confirm the relevant robot status and mastering record rather than masking installation errors with parameter changes.
ABB 3HAC021204-001 belongs to the IRB 6650S balancing-device context, while ABB 3HAC021353-001 is an IRB 2400 Yaskawa axis-4 motor.
ABB 3HAC021204-001 requires arm support and the documented press/service method before the balancing device is released.
ABB 3HAC021353-001 is the Yaskawa motor unit for axis 4, located with the axes 4–6 motors on the back of the IRB 2400 upper arm.
Do not assume substitution for ABB 3HAC021353-001. The IRB 2400 manual states that different motor executions are not compatible.
For ABB 3HAC021204-001, check arm movement and support behavior; for ABB 3HAC021353-001, check direction, brake, feedback and mastering.
Include ABB 3HAC021204-001 or ABB 3HAC021353-001, robot variant, position, installed label, quantity and destination.
Moore Automation keeps exact industrial article references, requested quantities and available supporting records in one enquiry path. This helps separate parts that belong to different robots or service boundaries.
