About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X60SB
The B02-ACQ40X60SB is a 40mm bore, 60mm stroke double-acting JIS compact cylinder. The leading B02- prefix marks this as AirTAC's welding-industry dedicated variant of the base ACQ40X60SB, meaning it is mechanically identical to the standard model but targeted for welding-line automation. It delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa.
This unit includes a built-in piston magnet (-S) for position sensing and a male-thread piston rod (-B) sized M14x1.5 for direct load coupling. The hard-anodized aluminum body features a C-clip and riveted assembly to minimize axial footprint, while NBR elastomer bumpers absorb end-stop impact. Note that these bumpers are fixed, not field-adjustable, so high-energy cycles may require external shock absorption.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X60SB Is Used
Robot Spot Welding Clamp
Drives the moving electrode arm in a robotic spot welding gun, utilizing the 628.3 N extend force to maintain consistent tip pressure on steel panels.
Welding Fixture Locator
Positions and locks sheet metal brackets inside a welding jig, relying on the short C-clip body to fit within tight fixture clearances.
Gun Cleaning Station
Actuates the reaming cutter block against a resistance spot welding cap during automated tip dressing sequences.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X60SB the Right Cylinder?
When sizing this actuator, stepping down to a 32mm bore yields 402.1 N push at 0.5 MPa, whereas stepping up to a 50mm bore provides 981.8 N. This 40mm model strikes a middle ground for moderate clamping tasks. To confirm your order, verify the 40mm bore, 60mm stroke, PT1/8 port, male M14x1.5 rod thread, and the required magnetic sensor option.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve centers; the piston will drift. If your welding fixture requires fail-safe position holding, 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-ACQ40X60SB 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 operating pressure range is 0.15-1.0 MPa, and the speed range is 30-500 mm/s.
The B02- prefix simply designates this as a welding-industry dedicated variant of the ACQ40X60SB; the physical specifications, seals, and dimensions are identical to the base model. It uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions, so for high-speed approaches, you should add an external shock absorber.
