RV70E-118.5
Axis 6 RV Gear for ABB IRB 6660
The RV70E-118.5 is identified in the IRB 6660 spare-parts structure as the Axis 6 RV gear. The assembly is associated with the IRB 6660 robot family and the 118.5 reduction ratio configuration. Primary identification: RV70E-118.5
ABB spare-part references: 3HAC028121-004 / 3HAC028121-005 |

MAINTENANCE SCENARIO
When the Axis 6 Transmission Becomes Critical
In an IRB 6660 maintenance situation, the RV70E-118.5 becomes relevant when the Axis 6 mechanical transmission requires replacement or when the existing gear assembly can no longer support reliable robot motion. A mechanical transmission problem can affect wrist-axis movement, positioning consistency and production availability. For a production cell that depends on the robot for continuous handling, welding, material movement or other programmed operations, an unresolved mechanical fault can extend downtime and delay restart. Replacement check: Match the robot model, axis position, RV designation and ABB spare-part number before installation. For this model, 3HAC028121-004 and 3HAC028121-005 are associated with RV70E-118.5 variants.

BUYER QUESTIONS
RV70E-118.5 — Practical FAQ
|
|
|
01. How can I confirm the correct RV70E-118.5 variant?
Confirm the robot model, axis position and the ABB spare-part number. RV70E-118.5 is associated with 3HAC028121-004 and 3HAC028121-005, which represent different product variants. |
02. Is RV70E-118.5 used on the IRB 6660 Axis 6?
Yes. The IRB 6660 spare-parts structure identifies RV 70E-118.5 as the RV gear for Axis 6. |
|
03. Why does RV70E-118.5 matter when an IRB 6660 cell is down?
Because the component belongs to the robot's Axis 6 mechanical transmission, an unsuitable or unavailable replacement can delay mechanical restoration and therefore extend production downtime. |
04. Can 3HAC028121-004 and 3HAC028121-005 be treated as identical?
They share the RV70E-118.5 designation, but the product descriptions distinguish the variants by finish/color. Match the actual robot configuration and required part number before ordering. |
|
05. What should I send when requesting an RV70E-118.5 replacement?
Please provide the exact Part Number, Quantity, Destination, Required Date and Machine/System. Including the robot model and axis position helps reduce the risk of matching the wrong mechanical variant. |
