Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ50X10S
The AirTAC Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ50X10S is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø50mm bore and 10mm stroke, PT1/4 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-ACQ50X10S
The B02-ACQ50X10S is a double-acting JIS compact cylinder built for welding-line automation. The leading B02- prefix marks this as AirTAC's welding-industry dedicated variant of the ACQ50X10S, meaning it is mechanically identical to the base model but targeted at spot and robot welding cells. It delivers 981.8 N of push force and 824.6 N of pull force at 0.5 MPa.
A short C-clip and riveted piston-to-rod assembly minimize overall length, saving axial mounting depth where a round-body cylinder will not fit. The 50 mm bore features a 20 mm rod, a PT1/4 port, and a fixed NBR elastomer bumper at each end that absorbs end stops without requiring field adjustment. Because the -S option is present, a built-in piston magnet enables position detection using AirTAC reed or electronic switches housed in the grooves around the body.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ50X10S Is Used
Robot Welding Clamp
Drives short-stroke clamping arms in robotic spot welding cells, using its 981.8 N push at 0.5 MPa to hold steel panels firmly during the weld cycle.
Welding Fixture Locating
Positions locating pins on welding jigs where axial depth is restricted, leveraging the compact C-clip body to fit between tight tooling plates.
Part Ejection Station
Pushes finished welded assemblies out of the cell using the 10 mm stroke, with the -S magnet triggering an electronic switch to confirm ejection.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ50X10S the Right Cylinder?
When sizing this actuator, stepping down to a 40 mm bore yields 628.3 N push at 0.5 MPa, while stepping up to a 63 mm bore provides 1558.6 N push at 0.5 MPa. This 50 mm option strikes a balance for medium-duty fixturing. Confirm your ordering essentials: 50 mm bore, 10 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the -S magnet for sensing. Keep in mind that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered; the rod drifts, and the fixed bumper only decelerates it near the stroke end. For a fail-safe hold, an external rod lock or pilot-operated check valve is required.
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-ACQ50X10S FAQ
At 0.5 MPa, the push force is 981.8 N and the pull force is 824.6 N. At 0.7 MPa, the push force is 1374.4 N. The maximum push force is 200 kgf at 1.0 MPa.
The B02- prefix designates this as a welding-industry dedicated variant of the ACQ50X10S, though mechanically it shares the exact same physical specs. It uses a fixed NBR elastomer bumper at each end to absorb the end stop, which is not field-adjustable. For high-speed or high-energy loads, add an external shock absorber or slow the approach.
