Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X50
The AirTAC Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X50 is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø40mm bore and 50mm stroke, PT1/8 air ports and a C-clip / riveted short body that saves mounting depth. Magnetic-switch slots around the body accept position sensors.

About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X50
The B02-ACQ40X50 is a double-acting JIS compact cylinder built for welding-line automation, mechanically identical to the standard ACQ40X50. The B02- prefix simply designates its application focus for fixturing and clamping in robotic welding cells. It delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa.
A short C-clip and riveted piston-to-rod assembly minimize overall length, saving axial mounting depth where a conventional round-body cylinder cannot fit. The 16 mm piston rod uses a female M8x1.25 thread, and end-stop energy is absorbed by a fixed NBR elastomer bumper rather than an adjustable air cushion.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X50 Is Used
Spot Welding Gun Clamping
Provides precise 628.3 N clamping force at 0.5 MPa to hold sheet metal panels together during automated robotic spot welding operations.
Weld Cell Fixture Positioning
Cycles a 50 mm stroke to locate and release heavy steel brackets within a dedicated welding fixture, utilizing the short C-clip body to minimize machine footprint.
Frame Assembly Pin Insertion
Drives a locating pin into tubular steel frames prior to MIG welding, relying on the 16 mm rod and fixed NBR bumper to endure repetitive end-stop impacts.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X50 the Right Cylinder?
This 40 mm bore generates 628.3 N of push force at 0.5 MPa. If your welding fixture needs less clamping pressure, stepping down to the 32 mm bore yields 402.1 N. For heavier weldment holding, the 50 mm bore provides 981.8 N. Note that a plain compact cylinder drifts if air pressure is lost; for fail-safe load holding on a vertical clamp, add an external rod lock or pilot-operated check valve. When ordering, confirm the 50 mm stroke, PT1/8 port, female M8x1.25 rod thread, and whether a magnetic switch is needed (this base SKU ships without 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-ACQ40X50 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 indicates this unit is part of AirTAC's welding-industry dedicated line, but it is mechanically identical to the standard ACQ40X50. It does not have adjustable air cushions; instead, it uses a fixed NBR elastomer bumper at each end to absorb end-stop energy. For high-speed approaches, an external shock absorber is recommended.
