About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X25S
The B02-ACQ32X25S is a double-acting JIS compact cylinder delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The leading "B02-" prefix marks this as AirTAC's welding-industry dedicated variant of the ACQ32X25S, mechanically identical to the base model and built for fixturing and clamping within robot welding cells. Its short C-clip and riveted body design drastically reduces axial mounting depth compared to round-body alternatives.
This 32 mm bore unit features a 16 mm piston rod, a PT1/8 port, and a built-in piston magnet (-S) for position sensing. Instead of an adjustable air cushion, it relies on a fixed NBR elastomer bumper at each end to absorb the end stop. Because the bumper cannot be tuned, high-speed approaches may require an external shock absorber to manage kinetic energy.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X25S Is Used
Robot Welding Cell Clamping
Secures mild steel fixtures in spot welding lines, utilizing the 402.1 N extend force to hold parts firmly against locators while maintaining a minimal footprint.
MIG Gun Positioning
Indexes welding torch brackets into the correct joint gap, relying on the 25 mm stroke and fixed NBR bumper to absorb the stop impact in tight robotic cells.
Assembly Line Ejection
Pushes completed welded subframes out of the fixture, using the 301.6 N retract force to cycle quickly at speeds between 30-500 mm/s.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X25S the Right Cylinder?
When sizing this 32 mm bore actuator, consider stepping down to the 25 mm bore if your load requires less force (245.4 N push at 0.5 MPa), or stepping up to the 40 mm bore for greater thrust (628.3 N push at 0.5 MPa). Keep in mind that a plain 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 load holding, an external rod lock or pilot-operated check valve is required.
To order, confirm the 32 mm bore, 25 mm stroke, PT1/8 port, and the built-in magnet (S) for AirTAC reed or electronic switches. The standard rod end features a female M8x1.25 thread, and the maximum standard stroke available for this bore is 100 mm.
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-ACQ32X25S FAQ
This 32 mm bore double-acting 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 force of 82 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
The B02- prefix simply denotes AirTAC's welding-industry dedicated variant of the ACQ32X25S; it shares the exact same physical specs as the base model. It does not have an adjustable air cushion; instead, it uses a fixed NBR elastomer bumper at each end to decelerate the piston. If your welding automation runs at high speeds, you should add an external shock absorber or slow the approach.
