About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X40
The B02-ACQ32X40 is a double-acting JIS compact cylinder delivering 402.1 N of push force at 0.5 MPa. The B02- prefix designates this as AirTAC's welding-industry dedicated variant of the standard ACQ32X40, mechanically identical to the base model and built for fixturing or clamping in robotic welding cells. Its short C-clip and riveted body design drastically reduce axial mounting depth compared to round-body alternatives.
This 32 mm bore unit features a 16 mm piston rod and a PT1/8 port. It relies on a fixed NBR elastomer bumper at each end to absorb end-stop impact rather than an adjustable air cushion. The body includes magnetic-switch grooves, though this specific SKU ships without the internal magnet.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X40 Is Used
Spot Welding Gun Clamping
Provides the 402.1 N clamping thrust needed to hold steel panels together in robotic spot welding guns before the electrodes fire.
Welding Fixture Positioning
Pushes parts into the exact weld location inside automated welding cells, utilizing the short 40 mm stroke to minimize overall fixture depth.
Assembly Line Ejection
Ejects finished welded sub-assemblies from machining jigs at operating speeds between 30 and 500 mm/s.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X40 the Right Cylinder?
If 402.1 N push at 0.5 MPa is too much force, step down to the 25 mm bore which provides 245.4 N. If you need greater thrust, the 40 mm bore offers 628.3 N. This model is configured with a 40 mm stroke, PT1/8 port, female M8x1.25 rod-end thread, and no sensor magnet. Note that a plain compact cylinder like this will drift and cannot hold a load if air pressure is lost or the valve is centered; use an external rod lock or pilot-operated check valve for fail-safe positioning in welding fixtures.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Handle the C-clip carefully; seat it fully in its groove.
- check Installation by qualified personnel per AirTAC docs.
Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X40 FAQ
At 0.5 MPa, the push force is 402.1 N and the pull force is 301.6 N. At 0.7 MPa, the push force is 562.9 N. The maximum push force is 82 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
The B02- prefix simply marks this as the welding-industry dedicated version of the ACQ32X40, sharing identical specifications. It does not have adjustable air cushions; instead, it uses fixed NBR elastomer bumpers at both stroke ends. For high-energy welding ejection cycles, consider adding an external shock absorber.
