ABB 3HAC021724-001 / 3HAC021455-001 / 3HAC040499-001 – Robot Axis Gearbox | IRB4400 / IRB1600 / RB460 Platform
Engineering Background
ABB’s IRB4400, IRB1600, and RB460 series represent the backbone of high-throughput industrial automation in automotive, electronics, and general manufacturing. The axis gearbox is the single most mechanically critical sub-assembly in these robots — governing repeatability, torque transmission, and service life. Part numbers 3HAC021724-001, 3HAC021455-001, and 3HAC040499-001 are OEM-designated gearbox units covering specific axis positions across these platforms.
Product Positioning
Konmask.com supplies these gearboxes to maintenance engineers, system integrators, and OEM rebuild shops requiring verified, traceable replacement units. Each unit is sourced through qualified channels and undergoes functional inspection before dispatch.

System Architecture & Signal Flow
The gearbox interfaces directly between the servo motor output shaft and the robot arm link. In ABB IRC5 / S4C+ controller architectures, the axis drive module delivers torque commands via the motor; the gearbox reduces speed and multiplies torque to the mechanical arm. Backlash compensation is managed at the controller level — correct gearbox specification is essential to maintain the calibrated compensation values stored in the robot’s SMB (Serial Measurement Board).
- Motor → Gearbox Input Flange → Reduction Stage → Output Flange → Robot Link
- Encoder feedback loop remains unaffected by gearbox replacement when OEM specs are maintained.
- Post-installation: fine calibration via ABB RobotStudio or teach pendant recommended.
Sourcing & Quality Verification
- Units sourced from ABB-authorized distributors and certified secondary market channels.
- Pre-shipment inspection: visual, dimensional, and rotational resistance check.
- Packaging: industrial foam-lined crating with moisture barrier for international freight.
- Documentation available: packing list, inspection report, certificate of conformity (on request).

Technical FAQ
Q: Are 3HAC021724-001, 3HAC021455-001, and 3HAC040499-001 interchangeable?
A: No. Each part number corresponds to a specific axis and robot model. Confirm your robot model and axis number before ordering.
Q: Is recalibration required after gearbox replacement?
A: Yes. ABB recommends fine calibration after any axis gearbox replacement. The base calibration data stored in the SMB should be verified and updated as needed.
Q: Can you supply the gearbox with the servo motor?
A: Yes. Konmask.com can supply matched motor-gearbox assemblies. Specify your requirement at inquiry.
Q: What is the typical lead time?
A: In-stock units ship within 3–5 business days. Out-of-stock items are subject to sourcing lead time — typically 2–6 weeks.
Q: Do you provide installation support?
A: We provide technical documentation and remote guidance. On-site support can be arranged through our partner network.
