About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X75SB
The AirTAC B02-ACQ32X75SB is a double-acting JIS compact cylinder engineered for welding-line automation. The B02- prefix designates this as a welding-industry dedicated variant of the base ACQ32X75SB, meaning it shares the exact same physical specifications—delivering 402.1 N of push force and 301.6 N of pull force at 0.5 MPa—while being tailored for fixturing and clamping in robotic weld cells. Its short C-clip and riveted body construction drastically reduces axial footprint compared to traditional round-body cylinders, fitting neatly into tight machine spaces.
This specific configuration includes an integrated piston magnet (-S) for position sensing using AirTAC reed or electronic switches, and a male-thread piston rod (-B) sized M14x1.5 for direct load coupling. The 32 mm bore utilizes a PT1/8 port and relies on a fixed NBR elastomer bumper at each end to absorb end-stop impact. Because this bumper is not an adjustable air cushion, operators should slow the approach speed or utilize external shock absorbers for high-energy welding gantry movements.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X75SB Is Used
Robot Welding Cell Clamping
Secures mild steel stampings in a robotic MIG welding station, utilizing the 402.1 N push force to hold parts firmly against locators while resisting vibration during the weld cycle.
Spot Welding Gun Actuation
Drives the lower arm of a resistance spot welding gun, where the short C-clip body minimizes overall machinery depth and the male M14x1.5 rod thread directly mounts the electrode holder.
Weld Fixture Indexing
Moves small indexing pins in and out of a multi-station weld fixture, relying on the built-in magnet to trigger electronic switches that confirm pin retraction before the table rotates.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X75SB the Right Cylinder?
When sizing this 32 mm bore actuator, evaluate your force margins carefully. Stepping down to a 25 mm bore reduces the 0.5 MPa push capacity to 245.4 N, whereas stepping up to a 40 mm bore increases it to 628.3 N. This B02-ACQ32X75SB configuration operates at 30-500 mm/s, features a 75 mm stroke (well within the 100 mm standard limit for this bore), and includes the male M14x1.5 rod end alongside the magnetic sensor option. Ensure your ordering essentials match these exact port and thread requirements.
Note that a standard compact cylinder of this type does not inherently hold its position if air pressure is lost or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the rod near the stroke end rather than locking it. For fail-safe load holding on vertical welding clamps, an external rod lock or a pilot-operated check valve must be integrated into your pneumatic circuit.
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-ACQ32X75SB FAQ
The B02- prefix indicates this is a welding-industry dedicated variant of the ACQ32X75SB, mechanically identical to the base model. It is a 32 mm bore double-acting cylinder that generates 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa.
No, this actuator uses a fixed NBR elastomer bumper at the stroke ends rather than an adjustable air cushion. For high-speed or high-energy loads, you should reduce the approach speed via flow controls or install an external shock absorber to prevent premature wear.
