About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X60S
The B02-ACQ40X60S is a double-acting, single-rod JIS compact cylinder engineered for welding-line automation. The leading "B02-" prefix designates this as AirTAC's welding-industry dedicated variant of the standard ACQ40X60S; mechanically, it shares the exact same physical specifications, delivering 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 length compared to traditional round-body units, saving valuable mounting depth inside dense robotic weld cells.
This 40 mm bore unit features a 16 mm piston rod and a PT1/8 port. Because it carries the "S" option code, a built-in piston magnet is included for position sensing via AirTAC reed or electronic switches mounted in the body grooves. Instead of an adjustable air cushion, the cylinder relies on a fixed NBR elastomer bumper at each end to absorb end-stop impact. Buyers should note that this bumper only decelerates the piston near stroke end and does not function as a braking lock.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X60S Is Used
Robot Spot Welding Clamp
Drives the moving electrode arm on a robotic spot welding gun, utilizing the 628.3 N push force to maintain consistent tip pressure on automotive body panels.
Welding Fixture Locating Pin
Actuates locating pins inside a multi-station weld fixture, where the 60 mm stroke positions parts accurately before the actual welding sequence begins.
MIG Torch Positioning
Indexes a MIG welding torch bracket into the correct joint path, relying on the short C-clip body to minimize axial footprint within a cramped robotic cell.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X60S the Right Cylinder?
When sizing this model, consider stepping down to the 32 mm bore for lighter clamping loads, which provides 402.1 N of push at 0.5 MPa, or moving up to the 50 mm bore for heavier fixturing, offering 981.8 N of push at 0.5 MPa. This 40 mm bore strikes a balance for 60 mm stroke requirements within standard welding fixtures. Remember that a standard compact cylinder like this will drift and lose its position if air pressure drops or the valve is centered; for fail-safe load holding on a vertical weld clamp, an external rod lock or pilot-operated check valve is required.
To order, confirm the 40 mm bore, 60 mm stroke, PT1/8 port, and the built-in magnet (S). The rod end features a default female M8x1.25 thread for straightforward load coupling. Operating speed ranges from 30-500 mm/s, but for high-energy welding automation cycles, adding an external shock absorber or slowing the approach speed is recommended to protect the fixed NBR bumper.
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-ACQ40X60S FAQ
This 40 mm bore cylinder provides a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push force is 879.6 N, and the maximum push force is 128 kgf at 1.0 MPa. The 60 mm stroke falls well within the 100 mm maximum standard stroke limit for this bore.
The B02- prefix simply marks this as the welding-industry dedicated variant of the ACQ40X60S; it is mechanically identical to the base cylinder without any special seals or coatings. To handle end-stop impact, it uses a fixed NBR elastomer bumper rather than an adjustable air cushion, so for high-speed welding automation you may need to slow the approach or add an external shock absorber.
