About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X200B
The B02-ACQ40X200B is a double-acting JIS compact cylinder where the B02- prefix designates it as AirTAC's welding-industry dedicated variant of the standard ACQ40X200B. Mechanically identical to the base model, 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 significantly reduces axial footprint compared to round-body alternatives, making it ideal for tight welding cell fixturing.
This specific unit features a 200 mm stroke, placing it in the long-stroke made-to-order category for the Ø32-Ø100 range, which extends up to 300 mm. It is equipped with a male M14x1.5 piston rod thread for direct load coupling, uses a PT1/8 port, and relies on a fixed NBR elastomer bumper at each end rather than an adjustable air cushion. The body includes magnetic-switch grooves, though this particular SKU ships without the internal magnet.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X200B Is Used
Robot Welding Cell Clamping
Secures heavy steel assemblies in automated robotic MIG welding stations, using the 628.3 N extend force to hold parts firmly against locators during the weld cycle.
Spot Weld Gun Actuation
Drives the moving arm of resistance spot weld guns on automotive body-in-white lines, where the compact C-clip body minimizes protrusion into tight tooling spaces.
Fixture Indexing Gates
Opens and closes safety or positioning gates on welding pallets, utilizing the 200 mm stroke to clear large workpieces before the welding robot enters the cell.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X200B the Right Cylinder?
When sizing this actuator, consider stepping down to the Ø32 bore or up to the Ø50 bore. The Ø32 provides 402.1 N push at 0.5 MPa, while the Ø50 offers 981.8 N, giving you room to adjust if the 628.3 N output of this 40 mm bore needs scaling. Because this is a 200 mm long-stroke variant, ensure your welding cell has the lateral stability to support the extended travel without binding the 16 mm rod.
Keep in mind that a standard ACQ body does not hold its position if air pressure is lost or the valve is centered; the rod will drift, and the fixed NBR bumper only decelerates the piston near the stroke ends. For fail-safe holding of a welding fixture, you must integrate an external rod lock or a pilot-operated check valve. To order, confirm the 40 mm bore, 200 mm stroke, PT1/8 port, male M14x1.5 rod thread, and the absence of a sensor magnet.
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-ACQ40X200B FAQ
This 40 mm bore cylinder delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa, a push force of 879.6 N at 0.7 MPa, and a maximum push force of 128 kgf at 1.0 MPa. Because the stroke is 200 mm, it exceeds the 100 mm standard maximum for this bore and is classified as a long-stroke made-to-order variant.
The B02- prefix indicates this is AirTAC's welding-industry dedicated line of the ACQ40X200B, meaning it is mechanically identical to the base model but targeted at welding automation applications. It does not have adjustable air cushions; instead, it uses fixed NBR elastomer bumpers at both stroke ends to absorb impact, so external shock absorbers may be needed for high-energy loads.
