The AirTAC Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X20B is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø32mm bore and 20mm 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.
The B02-ACQ32X20B is a double-acting JIS compact cylinder where the B02- prefix designates it as AirTAC's welding-industry dedicated variant of the standard ACQ32X20B. Mechanically identical to the base model, it delivers 402.1 N of push force and 301.6 N of pull force at 0.5 MPa. The short C-clip and riveted piston-to-rod assembly drastically reduces overall length, saving valuable axial mounting depth in tight robotic weld cells.
This specific unit features a male-thread piston rod end (M14x1.5) for direct load coupling, a 16 mm rod diameter, and PT1/8 ports. Instead of an adjustable air cushion, it relies on a fixed NBR elastomer bumper at each end to absorb the end stop. The body includes magnetic-switch grooves, though this particular SKU ships without the internal magnet.

Thread: PT standard (G / NPT available). Related ACQ-family variants: ASQ (single-acting push), ATQ (single-acting pull), ACQD (double rod), ACQJ (adjustable stroke), TACQ (guided / non-rotating).
Utilizes the 402.1 N extend force to hold upper and lower gun arms during robotic spot welding, where the short body length prevents interference with tooling.
Moves small locating pins or stops on a welding fixture table with a 20 mm stroke, using the male M14x1.5 thread to secure the mechanism directly.
Pushes finished welded assemblies out of the fixture using the 301.6 N retract force, operating at speeds between 30 and 500 mm/s.
When sizing your welding fixtures, compare this 32 mm bore (402.1 N push @0.5 MPa) against the next size down, the 25 mm bore (245.4 N push), or the next size up, the 40 mm bore (628.3 N push) to ensure proper clamping force. Remember that a plain compact cylinder like this does not hold its load if air pressure drops or the valve is centered; the rod will drift, and the fixed bumper only decelerates near the stroke end. For a fail-safe clamp in automated welding, add an external rod lock or pilot-operated check valve. Ordering essentials to verify: 32 mm bore, 20 mm stroke, PT1/8 port, male M14x1.5 rod thread, and no sensor magnet.
Quick checklist
The B02- prefix indicates this is AirTAC's welding-industry dedicated line of the ACQ32X20B, sharing the exact same physical specs as the base model. At 0.5 MPa it provides 402.1 N push and 301.6 N pull; at 0.7 MPa it provides 562.9 N push. The maximum push force is 82 kgf at 1.0 MPa.
No, it uses a fixed NBR elastomer bumper at each end rather than a field-adjustable air cushion, so for high-energy welding automation you may need external shock absorbers. Additionally, while the body has sensor grooves, this SKU lacks the -S code and ships without a magnet for reed or electronic switches.
