More Information

Overview Manuals IRB 6600 Match Follow-Up Path Variant Planning Product Applications

Features:

  • Balancing Device B: ABB uses this exact product name for 3HAC12604-1.
  • IRB 6600 reference: The official spare-part record associates the article with the IRB 6600 robot family.
  • Legacy follow-up: ABB directs the discontinued article to 3HAC020691-001, named Balancing Device A.
3HAC12604-1 identifies Balancing Device B within ABB's IRB 6600 spare-part structure. The lettered device name is part of the service identity and should stay visible during procurement.

The IRB 6600 family includes variants with different arm lengths and handling capacities. An exact article match therefore matters when the balancing-device scope is planned for an installed robot.

ABB provides a follow-up article for the discontinued part, but the follow-up name changes from Device B to Device A. Treating that record as a controlled migration rather than an assumed direct swap reduces ambiguity before mechanical service begins.
For 3HAC12604-1 support, provide the installed IRB 6600 variant and both balancing-device identifiers so the legacy service path can be reviewed.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Robot-family anchor: ABB associates 3HAC12604-1 with the IRB 6600 family.
  • Variant boundary: IRB 6600 robots were offered with different arm lengths and handling capacities.
  • Exact article check: Match the installed balancing-device plate rather than selecting only by the IRB 6600 family name.
  • Scope limit: The official record does not extend this article to other ABB robot families.
  • Source article: 3HAC12604-1 is named Balancing Device B in the ABB spare-part record.
  • Follow-up article: ABB lists 3HAC020691-001 as the follow-up item.
  • Name change: The follow-up is named Balancing Device A, not Balancing Device B.
  • Decision boundary: The record supplies a migration route but does not declare an unconditional drop-in replacement.
  • Arm-length variants: IRB 6600 configurations were supplied with different arm lengths for process adaptation.
  • Handling variants: The robot family also used different handling capacities, so family membership alone is not a complete parts match.
  • Dense-line motion: ABB describes the IRB 6600 as able to bend fully backwards for expanded working range in dense lines.
  • Service information: The robot family's Service Information System monitors motion and load to support maintenance planning.
  • Spot welding: IRB 6600 robots are documented for spot-welding production, where the exact balancing-device configuration remains robot-specific.
  • Machine tending: The IRB 6600 family supports machine-tending applications requiring the installed mechanical configuration to be preserved.
  • Material handling: ABB lists material handling as a primary IRB 6600 application for its high-payload robot variants.
Description
IRB 6600 maintenance uses 3HAC12604-1 as the exact Balancing Device B spare-part identity. Keeping the order tied to that designation helps service teams avoid treating every balancing device in the robot family as the same mechanical configuration.

For legacy service planning, 3HAC12604-1 carries an ABB follow-up record to 3HAC020691-001, whose name changes to Balancing Device A. That named transition gives procurement a traceable migration route while making the designation change visible before the installed IRB 6600 configuration is committed to replacement work.

Technical notes
ABB lists follow-up 3HAC020691-001, named Balancing Device A, for 3HAC12604-1 but does not state drop-in interchangeability in the record. Because the device designation changes from B to A, treat the follow-up as a migration path and stop the order until the installed IRB 6600 configuration is matched.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can 3HAC12604-1 be selected using only an IRB 6600 robot-family name?
No. IRB 6600 includes variants with different arm lengths and handling capacities, while this article is specifically Balancing Device B. Match the installed device identity before ordering.
Is 3HAC12604-1 automatically interchangeable with ABB follow-up 3HAC020691-001?
Not from the product record alone. ABB names a follow-up path, but the designation changes from Balancing Device B to Balancing Device A; hold installation until the robot configuration and mechanical scope are confirmed.
Does a spot-welding IRB 6600 necessarily use 3HAC12604-1?
No. Spot welding is an IRB 6600 application, not proof of this exact balancing-device article. Use the installed part plate or robot spare-parts documentation as the deciding evidence.
What should maintenance do when the label on an IRB 6600 does not match 3HAC12604-1?
Stop the parts substitution. This product is specifically named Balancing Device B, and a different label may indicate another variant or the later Balancing Device A path.
Can 3HAC12604-1 be ordered for a non-IRB 6600 ABB robot?
The audited ABB record supports IRB 6600 only. Do not extend the article to another robot family without that robot's own spare-parts record naming the same full article number.
How should a buyer handle an offer for 3HAC12604-1 after OEM discontinuation?
Require the offer to preserve the exact Balancing Device B identity. If the quotation supplies 3HAC020691-001 instead, treat it as a migration proposal and obtain configuration approval before release.
