About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X10SB
The B02-ACQ40X10SB is a double-acting JIS compact cylinder delivering 628.3 N push and 527.8 N pull at 0.5 MPa. The leading "B02-" prefix designates this as AirTAC's welding-industry dedicated line, mechanically identical to the standard ACQ40X10SB and built for fixturing in robot welding cells.
Its short C-clip and riveted body drastically reduce axial footprint compared to round-body units. This specific unit includes the -S magnet for AirTAC reed or electronic switches, and the -B male M14x1.5 rod end for direct load coupling. End-stops rely on a fixed NBR elastomer bumper, not an adjustable air cushion.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X10SB Is Used
Robot Welding Clamp
Provides 628.3 N of clamping force at 0.5 MPa to hold steel assemblies firmly in place during automated robotic MIG welding sequences.
Spot Weld Gun Actuator
The 10mm short stroke and male M14x1.5 rod drive the moving electrode of a spot weld gun, saving axial depth in dense automotive body-in-white tooling.
Weld Fixture Indexing
Uses the integrated magnet with electronic switches to confirm pin retraction on a welding table, ensuring parts clear the torch path before the next cycle.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X10SB the Right Cylinder?
For sizing context, stepping down to a 32mm bore yields 402.1 N push at 0.5 MPa, while stepping up to a 50mm bore provides 981.8 N. This 40mm bore with a 10mm stroke fits extremely tight welding fixtures. Note that a plain compact cylinder drifts if air pressure is lost; for fail-safe holding of a heavy weldment, add an external rod lock or pilot-operated check valve. Confirm ordering essentials: PT1/8 port, 16mm rod, male M14x1.5 thread, and the integrated 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-ACQ40X10SB FAQ
At 0.5 MPa it provides 628.3 N push and 527.8 N pull; at 0.7 MPa push is 879.6 N. The maximum push force is 128 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, proof pressure is 1.5 MPa, and speed ranges from 30-500 mm/s.
The B02- prefix simply marks this as the welding-industry dedicated variant of the ACQ40X10SB; it shares the exact same physical specs. It does not have adjustable air cushions. Instead, it uses a fixed NBR elastomer bumper at each end to absorb the stop. For high-energy welding automation, slow the approach or add external shock absorbers.
