About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X100B
The B02-ACQ40X100B is AirTAC's welding-industry dedicated variant of the standard ACQ40X100B JIS compact cylinder, mechanically identical to the base model. The leading "B02-" prefix simply designates its application focus for welding-line automation, meaning the physical specifications remain unchanged. As a double-acting single-rod actuator, it delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. Its short C-clip and riveted body construction drastically reduces axial mounting depth compared to traditional round-body cylinders, which is critical when space is tight on a dense welding fixture.
This specific unit ships with a male-thread piston rod end (M14x1.5) for direct load coupling, paired with a 16 mm rod diameter. It does not include a sensor magnet, though the body retains the standard magnetic-switch grooves for future upgrades. Deceleration at the stroke ends relies on a fixed NBR elastomer bumper rather than an adjustable air cushion, absorbing impacts without requiring manual tuning. Operating speed ranges from 30 to 500 mm/s, and the fluid port size is PT1/8.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X100B Is Used
Robot Welding Cell Clamping
Secures mild steel brackets in a robotic spot-welding cell, using the 628.3 N extend force to hold parts firmly against locators while the short body clears the welding gun envelope.
Fixture Plate Positioning
Indexes small sub-assembly fixture plates on a linear slide, leveraging the 100 mm stroke to move components safely out of the robot's arc zone before unloading.
Spot Welder Gun Actuation
Drives the lower arm of a compact spot welder gun, where the male M14x1.5 rod threads directly into the moving electrode holder to deliver consistent clamping pressure.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X100B the Right Cylinder?
When sizing this actuator, compare its 628.3 N push force at 0.5 MPa against adjacent bores. Stepping down to a 32 mm bore yields 402.1 N, while stepping up to a 50 mm bore provides 981.8 N, allowing you to scale your fixturing force appropriately. Keep in mind that a plain ACQ body 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 end of travel. For a fail-safe hold on a welding fixture, you must integrate an external rod lock or a pilot-operated check valve.
To order, confirm the essentials: 40 mm bore, 100 mm stroke (the maximum standard stroke for this bore), PT1/8 port, no magnet, and the male M14x1.5 rod thread. If your welding cell requires position sensing, you would need to specify the -S option for the internal magnet to utilize 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-ACQ40X100B FAQ
At 0.5 MPa, the push (extend) force is 628.3 N and the pull (retract) 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 unit is the maximum standard stroke available for a 40 mm bore.
The B02- prefix indicates this is AirTAC's welding-industry dedicated line of the ACQ40X100B, meaning it is mechanically identical to the base cylinder without any special seals or coatings. It uses a fixed NBR elastomer bumper at each end to absorb end-stop shock; it is not an adjustable air cushion, so for high-energy welding cycles you may need external shock absorbers.
