About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X25B
The B02-ACQ32X25B is a double-acting, single-rod JIS compact cylinder engineered for welding-line automation. The leading "B02-" prefix designates this as AirTAC's welding-industry dedicated variant of the base ACQ32X25B; mechanically, it shares the exact same physical specifications, delivering 402.1 N of push force and 301.6 N of pull force at 0.5 MPa. Its short C-clip and riveted body construction drastically reduces axial footprint compared to round-body alternatives, fitting neatly into tight robotic weld cells.
This specific unit includes a male-thread piston rod end (M14x1.5) for direct load coupling and uses a PT1/8 port. Because it lacks the -S suffix, it ships without a sensor magnet, though the body retains magnetic-switch grooves for future retrofitting. End-of-travel deceleration is handled by a fixed NBR elastomer bumper rather than an adjustable air cushion, ensuring reliable stopping in compact fixturing spaces.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X25B Is Used
Robotic Spot Welding Guns
Drives the moving electrode arm in compact robotic spot welding guns where the short C-clip body saves critical axial depth and the 402.1 N push force securely clamps sheet metal panels.
Welding Fixture Clamps
Acts as a low-profile clamping cylinder on welding fixture tables, using the male M14x1.5 rod thread to hold tubular frames firmly in place during automated MIG welding cycles.
Part Transfer Gates
Indexes small transfer gates inside weld cells, relying on the fixed NBR bumper to absorb the end stop energy without requiring bulky external cushioning hardware.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X25B the Right Cylinder?
When sizing this actuator, consider stepping to the next bore down (Ø25) which provides 245.4 N push at 0.5 MPa, or moving up to the Ø40 bore which yields 628.3 N push at 0.5 MPa for heavier weld fixtures. This Ø32 model hits a strong middle ground with a 16 mm rod diameter and a 25 mm stroke, well within the 100 mm maximum standard stroke for this bore size. Keep in mind that a plain compact cylinder like this does not hold its position if air pressure is lost or the valve is centered; the rod will drift, and the fixed bumper only decelerates it near the stroke end. For fail-safe load holding, integrate an external rod lock or a pilot-operated check valve.
For ordering, confirm the essentials: 32 mm bore, 25 mm stroke, PT1/8 port, no sensor magnet, and the male M14x1.5 rod thread. If your welding application requires position feedback, you would need to specify the -S option to include the internal magnet for reed or electronic switches.
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-ACQ32X25B FAQ
This 32 mm bore cylinder provides a push force of 402.1 N and a pull force of 301.6 N at 0.5 MPa. At 0.7 MPa, the push force is 562.9 N, and the maximum push force is 82 kgf at 1.0 MPa. It operates between 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 indicates this is AirTAC's welding-industry dedicated variant of the ACQ32X25B; it is mechanically identical to the base model with no special seals or coatings. It does not have adjustable air cushions; instead, it uses a fixed NBR elastomer bumper at each end to absorb shock. For high-energy welding automation, you may need to add an external shock absorber or slow the approach speed.
