ABB 3HAC043075-001 Reduction Gear RV-42N-126 – IRB 6700 Robot Series
When a reduction gear fails on an ABB IRB 6700 industrial robot, the consequences are immediate and severe: the robot arm loses positional accuracy, torque transmission collapses, and the entire production line grinds to a halt. In high-throughput automotive welding cells or heavy-payload palletizing stations, even a few hours of unplanned downtime can cost tens of thousands of dollars. The ABB 3HAC043075-001 Reduction Gear RV-42N-126 is the precision-engineered component that keeps your IRB 6700 running at peak performance — and its absence is simply not an option.
The RV-42N-126 is a cycloidal reduction gear specifically designed for the joint axes of the ABB IRB 6700 robot family — one of ABB’s most successful and widely deployed heavy-duty industrial robot platforms globally. Cross-referenced under part numbers IRB67003HAC046336-003 and IRB67003HAC046336-004, this gearbox delivers the high reduction ratio, rigidity, and backlash-free performance demanded by precision automation in automotive, metal fabrication, foundry, and logistics industries worldwide.
