About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X30B
The B02-ACQ40X30B 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 ACQ40X30B, meaning it is mechanically identical to the base model while catering specifically to spot and robot welding cell fixturing. Operating at 0.15-1.0 MPa, it delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa.
This 40 mm bore unit features a 16 mm piston rod with a male M14x1.5 thread end for direct load coupling. The short C-clip and riveted body construction drastically reduces axial footprint compared to round-body alternatives. Instead of an adjustable air cushion, it relies on a fixed NBR elastomer bumper at each end to absorb end-stop impact. The body includes magnetic-switch grooves, though this specific SKU ships without the internal magnet.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X30B Is Used
Robot Welding Cell Clamping
Secures chassis components in a robotic MIG welding station, utilizing the 628.3 N push force to hold parts firmly against locators while maintaining a minimal axial profile.
Spot Welding Gun Actuation
Drives the moving arm of a resistance spot welding gun, where the 30 mm stroke provides rapid open/close action for high-throughput automotive body-in-white assembly.
Fixture Plate Indexing
Shifts welding fixture plates between stations on a transfer line, using the male M14x1.5 rod thread to attach tooling directly while handling the 527.8 N retract load.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X30B the Right Cylinder?
When sizing this actuator, stepping down to the 32 mm bore yields 402.1 N push at 0.5 MPa, while stepping up to the 50 mm bore provides 981.8 N. This 40 mm option supplies a robust 879.6 N at 0.7 MPa, striking a balance for mid-weight weld fixtures. Remember that a standard compact cylinder drifts if air pressure drops or the valve centers; the fixed NBR bumper only decelerates the piston near stroke end and cannot hold a load. For fail-safe positioning on a welding line, integrate an external rod lock or pilot-operated check valve. To order, confirm the 40 mm bore, 30 mm stroke, PT1/8 port, male M14x1.5 rod thread, and no 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-ACQ40X30B 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 reaches 879.6 N. The maximum push force is 128 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
The B02- prefix simply marks this as the welding-industry dedicated variant of the ACQ40X30B; it shares the exact same physical specs. It uses fixed NBR elastomer bumpers at both ends, not an adjustable air cushion. For high-speed welding automation, you may need to add external shock absorbers or slow the approach speed.
