Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X50S
The AirTAC Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X50S is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø32mm 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-ACQ32X50S
The B02-ACQ32X50S is a double-acting JIS compact cylinder delivering 402.1 N of push force at 0.5 MPa. The leading B02- prefix designates this as AirTAC's welding-industry dedicated variant of the standard ACQ32X50S. Mechanically identical to the base model, it is tailored for welding-line automation, fixturing, and robot spot-welding cells where axial space is tight.
The short C-clip and riveted piston-to-rod body design drastically reduces overall length compared to round-body alternatives. Because it includes the -S option, a built-in piston magnet enables position detection using AirTAC reed or electronic switches seated in the body grooves. Deceleration at stroke ends relies on a fixed NBR elastomer bumper rather than an adjustable air cushion, meaning high-energy welding clamp cycles may require slowing the approach speed.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X50S Is Used
Robot Spot Welding Clamp
Drives the moving electrode arm in automated robotic spot welding guns, utilizing the 50 mm stroke to close and form sheet metal weld nuggets rapidly.
Welding Fixture Locator
Positions and locks mild steel stampings inside a multi-point fixture, using the 402.1 N extend force to prevent part shift before the torch touches down.
Transfer Line Diverter
Pushes completed welded assemblies from the main conveyor onto an inspection spur, fitting within the tight 30-500 mm/s speed range of the cell.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ32X50S the Right Cylinder?
When sizing this actuator, stepping down to a 25 mm bore yields 245.4 N push at 0.5 MPa, while stepping up to a 40 mm bore provides 628.3 N. This 32 mm bore strikes a balance for medium-duty weld cell clamping. To confirm your ordering essentials: specify the 32 mm bore, 50 mm stroke, PT1/8 port, female M8x1.25 rod end, and the required -S magnet for sensing. Keep in mind that a plain compact cylinder drifts if air pressure drops; holding a heavy fixture safely during an air loss requires an external rod lock or pilot-operated check valve.
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-ACQ32X50S FAQ
This 32 mm bore double-acting cylinder provides 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 force of 82 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and uses a PT1/8 port.
The B02- prefix simply marks this as the welding-industry dedicated variant of the ACQ32X50S; it shares the exact same physical specs, including a fixed NBR elastomer bumper at each end. It does not feature an adjustable air cushion, so for high-speed welding operations you should slow the approach or add an external shock absorber.
