Description

ABB 3HAC028837-008 Gearbox TS245RHS i=125 FP – IRB 4600 Series Precision Axis Gearbox

When a critical axis gearbox fails on an ABB IRB 4600 robot, the entire production line stops. Whether it’s an automotive welding cell, a palletizing station, or a precision assembly line, unplanned downtime caused by a worn or damaged gearbox can cost thousands of dollars per hour. The ABB 3HAC028837-008 (also cross-referenced as 3HAC028837-006) Gearbox TS245RHS with gear ratio i=125 in FP (Full Package) configuration is the factory-specified replacement component that restores your robot to full operational accuracy — no compromise, no workaround.

Within the IRB 4600 family — ABB’s high-performance 6-axis industrial robot platform rated for payloads from 20 to 60 kg — this gearbox serves as a core motion-transmission element for one of the primary axes. The TS245RHS unit is a Nabtesco-type precision cycloidal gearbox, widely recognized in global industrial automation for its zero-backlash performance, long service life, and compatibility with high-cycle-rate applications. As a genuine ABB spare part, the 3HAC028837-008 is engineered to OEM tolerances and trusted by maintenance engineers across automotive, electronics, food & beverage, and logistics industries worldwide.

Frequently Asked Questions

Q: What is the difference between 3HAC028837-008 and 3HAC028837-006?: A: These are revision suffixes within the same ABB part family. The -008 is the current revision superseding -006. Both are functionally interchangeable for the IRB 4600 axis application. We can supply either revision — please specify your preference or robot build date when inquiring.
Q: Is this a genuine ABB part or an aftermarket replacement?: A: We supply genuine ABB OEM parts and certified refurbished units. The condition (new or refurbished) will be clearly stated in your quotation. We do not supply uncertified aftermarket gearboxes for safety-critical robot axes.
Q: How long does shipping take?: A: International express shipping (DHL/FedEx) typically takes 3–7 business days depending on destination. We ship from warehouses in China and can arrange urgent air freight for critical downtime situations.
Q: Do you provide installation support?: A: We provide technical documentation and can connect you with ABB-certified service engineers in your region. Gearbox replacement on the IRB 4600 requires axis calibration post-installation using ABB RobotWare.
Q: Can I get a warranty on this part?: A: Yes. All parts carry a 12-month warranty against manufacturing defects. Warranty claims require proof of proper installation and operation within rated parameters.
