ABB Drive Shaft Axis 5-6 3HAC11305-1 for IRB 1400 and IRB 1410
3HAC11305-1 is the ABB drive shaft for axes 5 and 6 of the IRB 1400 and IRB 1410 robots. ABB's IRB 1400 product manual lists it in the drive unit, axes 5-6 spare parts table as the "Driving shaft, 5-6", sitting alongside the axis 5 and axis 6 motor units, the motor end barriers, the timing belts and the plain washers that make up that drive group. It is the machined shaft pair that carries the wrist drive through the tubular shaft, and it is the part that has to move as one with the belt-driven motor units above it. Send us the article number on your original shaft and the robot nameplate, and we confirm the match before you order.

Industrial Applications
- IRB 1400 robots — ABB lists this shaft for the IRB 1400 M2004 and the IRB 1400-5/1,44 builds.
- IRB 1410 robots — the same wrist drive arrangement is used on the IRB 1410 family.
- Wrist service on axes 5 and 6 — the shaft is a service item whenever the wrist drive mechanism is dismantled for a motor, a belt or a barrier change.
- Cells with high wrist payload or frequent wrist motion — machining, deburring and grinding applications where the wrist axes cycle continuously and load the drive train.
- Maintenance stock for ageing robot lines, where a damaged shaft takes the whole wrist offline until the drive mechanism is rebuilt.
Design Purpose
- Carry the wrist drive from the two motor units down through the tubular shaft, so both wrist axes are driven from one motor pair by timing belt.
- Run in a pair, squeezed together at the tip so the assembly can pass through the tubular shaft on assembly and come out as one unit on disassembly.
- Hold the drive group against the upper arm assembly, since ABB lists this part against the upper arm assembly as well as the wrist.
- Work with the motor end barriers and the plain washers to keep the belt tension and the shaft alignment in place over the life of the robot.
Common Failure Modes
- Excessive play in axis 5 or axis 6 — ABB measures the maximum accepted play in axis 5 at 4.7 arc minutes. A shaft that has worn or a splined joint that has loosened shows up here first.
- Wrist position drift or an axis that will not hold its position under load — the drive from the motor units is no longer being transmitted cleanly.
- Noise, vibration or a grinding sound from the wrist during motion — worn splines or a shaft that has been driven with the belts out of tension.
- Bent or scored shaft surfaces — typically the result of a drive mechanism that was pulled out at an angle instead of along the tubular shaft.
- A wrist that has been dismantled and will not come back together correctly — the shaft pair has to be squeezed together at the tip to pass through the tube, and the screwed joint of the drive mechanism has to be tightened to 8.3 Nm ±10%.
- Damage found during a motor or belt change — the manual has the drive mechanism removed as a complete unit, so the shaft is normally exchanged at the same time as the motor units and the timing belts.
