Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X25SB
The AirTAC Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X25SB is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø32mm bore and 25mm stroke, PT1/8 air ports and a C-clip / riveted short body that saves mounting depth. Magnetic-switch slots around the body accept position sensors.

About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X25SB
The B02-ACQ32X25SB is a double-acting, single-rod JIS compact cylinder built for welding-line automation. The B02- prefix marks this as AirTAC's welding-industry dedicated variant of the standard ACQ32X25SB; mechanically it is identical, delivering a 402.1 N push and 301.6 N pull at 0.5 MPa. Its short C-clip and riveted body design drastically reduces axial footprint compared to round-body alternatives, fitting neatly into tight robotic weld cells.
This specific unit includes the -S magnet for position sensing via reed or electronic switches mounted in the body grooves, and the -B male M14x1.5 rod-end thread for direct load coupling. It features a 16 mm piston rod, a PT1/8 port, and relies on a fixed NBR elastomer bumper at each end to absorb end-stop energy rather than an adjustable air cushion.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X25SB Is Used
Spot Welding Gun Clamping
Provides 402.1 N of extend force at 0.5 MPa to position and hold lower gun arms in robotic spot welding fixtures.
Assembly Line Part Ejection
Uses the 25 mm stroke and male M14x1.5 rod to push completed welded sub-assemblies out of the cell quickly.
Transfer Conveyor Diverter
Actuates a diverter gate between welding stations, relying on the short C-clip body to fit within tight conveyor frame depths.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X25SB the Right Cylinder?
When sizing this 32 mm bore actuator, stepping down to a 25 mm bore yields 245.4 N push at 0.5 MPa, while stepping up to a 40 mm bore provides 628.3 N push at 0.5 MPa. Ensure your ordering essentials match this configuration: 32 mm bore, 25 mm stroke, PT1/8 port, built-in magnet (-S), and male M14x1.5 rod thread (-B). Note that a plain compact cylinder like this does not hold its position if air pressure drops; the rod drifts and the bumper only decelerates near the stroke end, so add an external rod lock or pilot-operated check valve if fail-safe holding is required.
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-ACQ32X25SB FAQ
At 0.5 MPa it provides 402.1 N push and 301.6 N pull; at 0.7 MPa the push is 562.9 N. The maximum push force is 82 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa, runs at 30-500 mm/s, and functions in -20 to +70 C temperatures.
The B02- prefix indicates this is AirTAC's welding-industry dedicated variant of the ACQ32X25SB, sharing the exact same physical specs as the base model. It uses a fixed NBR elastomer bumper at each end to absorb impacts, which is not field-adjustable; for high-speed welding ejection, add an external shock absorber or slow the approach.
