About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X20S
The B02-ACQ32X20S is a 32mm bore, 20mm stroke double-acting JIS compact cylinder. The leading B02- prefix designates this as AirTAC's welding-industry dedicated variant, mechanically identical to the standard ACQ32X20S. It delivers 402.1 N of push force and 301.6 N of pull force at 0.5 MPa, utilizing a short C-clip and riveted body design to minimize axial footprint in tight welding cell fixturing.
This unit includes the S option for a built-in piston magnet, allowing position detection via AirTAC reed or electronic switches seated in the body grooves. End-stopping relies on a fixed NBR elastomer bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorption. The 16mm rod uses a female M8x1.25 end thread, and the air supply connects via a PT1/8 port.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X20S Is Used
Robot Welding Cell Clamping
Secures mild steel brackets in a robotic MIG welding station, using its 402.1 N extend force to hold parts firmly against locators while maintaining a minimal axial profile behind the fixture.
Spot Weld Gun Actuation
Provides the 20mm reach needed to position lower spot weld gun arms on automotive body panels, cycling at 30-500 mm/s to maintain production line takt time.
Assembly Line Part Ejection
Pushes completed welded sub-assemblies out of a fixture onto a downstream conveyor, utilizing the magnetic S option to confirm full retraction before the next cycle begins.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X20S the Right Cylinder?
When sizing this actuator, stepping down to the 25mm bore yields 245.4 N push at 0.5 MPa, while stepping up to the 40mm bore provides 628.3 N. This 32mm option sits perfectly in the middle for medium-duty clamping. Because a standard double-acting cylinder drifts when air pressure is lost or the valve centers, holding a heavy weld fixture safely requires an external rod lock or pilot-operated check valve. To order, confirm the 32mm bore, 20mm stroke, PT1/8 port, built-in magnet, and female rod thread.
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-ACQ32X20S FAQ
At 0.5 MPa, this 32mm bore cylinder outputs 402.1 N push and 301.6 N pull. At 0.7 MPa, the push force is 562.9 N. The maximum push force is 82 kgf at the 1.0 MPa operating pressure limit. The maximum standard stroke available for this 32mm bore is 100 mm.
The B02- prefix simply indicates this unit is dedicated to welding-line automation applications, though it is mechanically identical to the base ACQ32X20S. It does not feature adjustable air cushions; instead, it uses a fixed NBR elastomer bumper at each end to absorb the impact. For high-speed or high-energy loads, an external shock absorber should be added.
