About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X100SB
The B02-ACQ40X100SB is a double-acting JIS compact cylinder where the B02- prefix designates it as AirTAC's welding-industry dedicated variant, mechanically identical to the standard ACQ40X100SB. It delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. The short C-clip and riveted body design drastically reduces axial footprint compared to round-body alternatives, fitting neatly into tight robotic welding cells.
This specific configuration includes a built-in piston magnet (-S) for position detection and a male-thread rod end (-B). The 16 mm rod utilizes an M14x1.5 male thread to couple directly to fixtures. Instead of an adjustable air cushion, it relies on fixed NBR elastomer bumpers at both ends to absorb end-stop impact. Operating speed ranges from 30-500 mm/s.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X100SB Is Used
Spot Welding Gun Clamping
Provides the 628.3 N extension force needed to hold sheet metal panels firmly against spot welding gun tips, ensuring electrical contact and minimizing warping during the weld nugget formation.
Robotic Cell Fixture Actuation
Utilizes the 100 mm stroke and male M14x1.5 rod to drive locating pins and clamps inside robotic welding cells, sequencing parts into position before the arc or laser process begins.
Weldment Transfer Ejection
Pushes completed welded assemblies out of the fixture station onto the exit conveyor, using the compact C-clip body to fit within the tight clearance of the welding enclosure.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X100SB the Right Cylinder?
When sizing this 40 mm bore option, stepping down to a 32 mm bore yields 402.1 N push at 0.5 MPa, while stepping up to a 50 mm bore provides 981.8 N push at 0.5 MPa. This 40 mm class offers a balanced middle ground for moderate clamping loads. Ensure your ordering essentials match the application: 40 mm bore, 100 mm stroke, PT1/8 port, male M14x1.5 rod thread, and the required sensor magnet.
Note 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. If your welding fixture requires a fail-safe hold to prevent part movement during an emergency stop, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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-ACQ40X100SB FAQ
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, the push force is 879.6 N. The maximum push force is 128 kgf at 1.0 MPa. The 100 mm stroke on this 40 mm bore is the maximum standard stroke available before moving into the long-stroke range (up to 300 mm).
The B02- prefix indicates this is AirTAC's welding-industry dedicated line, meaning it is mechanically identical to the standard ACQ40X100SB but targeted at welding automation. It does not have adjustable air cushions; it uses fixed NBR elastomer bumpers at both ends. For high-speed or high-energy welding operations, you should add an external shock absorber or slow the approach speed.
