ABB 3HAC021031-002 / 3HAC021127-005 IRB Balancing Device and Axis-3 Gearbox
01
Item Overview
ABB 3HAC021031-002 is a balancing-device assembly whose service record includes the piston-rod ear-bearing lubrication boundary, while ABB 3HAC021127-005 is an axis-3 gearbox used in the IRB 6640 context. They are separate mechanical assemblies with different stored-load and alignment risks.
On ABB 3HAC021031-002, bearing condition and correct lubrication affect the balancing-device support path. ABB 3HAC021127-005 transfers axis-3 motor torque through its specified gearbox execution, so mounting faces, gear engagement and joint support determine installation quality.
A service request for ABB 3HAC021031-002 or ABB 3HAC021127-005 should identify the robot, axis or balancing-device position and the exact installed article. The surrounding mechanical fault must be located before a complete assembly is ordered.

Installation Highlights
Installation Highlights for the exact ABB records
ABB 3HAC021031-002 and ABB 3HAC021127-005 require load control before disassembly and a clean, traceable mechanical installation.
Protect the interfaces
Keep bearings, mounting faces, gearbox openings and lubrication points clean; record shims and fastener positions.
Restore motion progressively
After assembly, verify free movement, lubrication status and abnormal noise at low speed before normal operation.
04
Diagnostics and Protection
Model-specific service context
3HAC021031-002 / 3HAC021127-005
ABB 3HAC021031-002 and ABB 3HAC021127-005 should be diagnosed at their mechanical interfaces before the complete assembly is treated as failed.
Localize bearing symptoms
For 3HAC021031-002, separate ear-bearing wear, lubrication loss and piston-rod damage from the rest of the balancing device.
Measure the axis-3 path
For 3HAC021127-005, evaluate backlash, noise and motor/gearbox interfaces before assigning the fault to the gearbox.
Protect after service
Reinstall guards, apply specified lubrication and verify torque and axis limits before returning the robot to production.
05
Practical Questions
Q01
What should be inspected before ordering ABB 3HAC021031-002?
A
Inspect the piston-rod ear bearing, support points and lubrication condition before ordering ABB 3HAC021031-002 as a complete balancing device.
Q02
How is ABB 3HAC021127-005 identified in the robot?
A
ABB 3HAC021127-005 is an axis-3 gearbox record for the IRB 6640 context; confirm the robot variant and installed gearbox label.
Q03
Why does ABB 3HAC021031-002 require the arm to be supported?
A
ABB 3HAC021031-002 carries stored mechanical load. Supporting the arm prevents uncontrolled movement during balancing-device work.
Q04
Which symptoms should be checked around ABB 3HAC021127-005?
A
For ABB 3HAC021127-005, inspect backlash, noise, lubricant evidence, motor interface and mounting condition before deciding the gearbox is faulty.
Q05
Can ABB 3HAC021031-002 and ABB 3HAC021127-005 share one installation procedure?
A
No. ABB 3HAC021031-002 is a balancing device and ABB 3HAC021127-005 is a gearbox, so the loads, tools and checks differ.
Q06
What supporting evidence is useful for ABB 3HAC021031-002 or ABB 3HAC021127-005?
A
Send the exact ABB 3HAC021031-002 or ABB 3HAC021127-005 article, robot identification, position, symptom, quantity and destination.
