About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X20
The AirTAC B02-ACQ32X20 is a double-acting JIS compact cylinder engineered for welding-line automation. The B02- prefix designates this as a welding-industry dedicated variant of the standard ACQ32X20, meaning it shares the exact same physical specs—delivering 402.1 N of push force and 301.6 N of pull force at 0.5 MPa—while being targeted at robotic spot welding and fixturing cells. Its short C-clip and riveted body construction drastically reduces overall axial length compared to round-body alternatives, fitting neatly into tight fixture zones.
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. Operating efficiently between 30-500 mm/s, it handles the 20 mm stroke rapidly for high-cycle clamping tasks.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X20 Is Used
Spot Welding Gun Clamping
Drives the lower arm of a robotic spot welding gun, using its 402.1 N push force to hold sheet metal panels flush during the weld nugget formation.
Weld Fixture Locating
Actuates short-stroke locating pins inside a multi-station welding jig, exploiting the compact C-clip body to fit within tight 32 mm fixture clearance zones.
Part Ejection from Cells
Pushes completed chassis sub-assemblies out of the welding robot envelope using a 20 mm stroke, relying on the fixed NBR bumper to quietly arrest the 30-500 mm/s travel.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X20 the Right Cylinder?
When sizing this actuator, consider stepping down to the 25 mm bore if your fixturing requires less force, which yields 245.4 N push at 0.5 MPa. Conversely, if your weldment demands heavier clamping, stepping up to the 40 mm bore provides 628.3 N push at 0.5 MPa. Remember that a standard compact cylinder like this does not hold its position if air pressure drops or the valve is centered; the rod will drift. For fail-safe clamping on a welding line, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 32 mm bore, 20 mm stroke, PT1/8 port, female M8x1.25 rod thread, and the absence of a magnet.
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-ACQ32X20 FAQ
This 32 mm bore cylinder provides 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, runs at speeds of 30-500 mm/s, and has a maximum standard stroke of 100 mm.
The B02- prefix simply marks this as AirTAC's welding-industry dedicated line of the ACQ32X20; it is mechanically identical to the base model without any special seals or coatings. It uses a fixed NBR elastomer bumper at the ends to absorb impact, not an adjustable air cushion. For high-energy welding automation, you may need to add an external shock absorber.
