About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X15S
The B02-ACQ40X15S is a double-acting JIS compact cylinder designed for welding-line automation, mechanically identical to the standard ACQ40X15S. The B02- prefix simply denotes its dedicated use in welding cells for fixturing and clamping, without altering the base pneumatics. It utilizes a short C-clip and riveted piston-to-rod assembly to drastically reduce axial length compared to round-body alternatives.
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore unit features a 16 mm piston rod and an M8x1.25 female thread. The integrated -S magnet allows position detection using AirTAC reed or electronic switches along the body grooves. End-stopping relies on a fixed NBR elastomer bumper rather than an adjustable air cushion.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X15S Is Used
Spot Welding Gun Clamping
Utilizes the 628.3 N extend force to hold sheet metal panels firmly in place during robotic spot welding, ensuring precise alignment.
Robot Cell Fixturing
Employs the 15 mm short stroke to quickly push locating pins into position within compact robotic welding enclosures.
Assembly Line Ejection
Leverages the 879.6 N push force at 0.7 MPa to positively eject welded sub-assemblies from the fixture onto the downstream conveyor.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X15S the Right Cylinder?
When sizing this actuator, stepping down to the 32 mm bore yields 402.1 N push at 0.5 MPa, while stepping up to the 50 mm bore provides 981.8 N. This 40 mm option effectively bridges mid-range clamping requirements. For this specific configuration, confirm the 15 mm stroke, PT1/8 port, female rod-end thread, and the required -S magnet for sensing.
Because a standard compact cylinder vents to atmosphere when air is lost or the valve centers, the rod will drift and cannot hold a load. If your welding fixture requires a fail-safe hold without live pressure, you must integrate an external rod lock or a 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-ACQ40X15S FAQ
This 40 mm bore cylinder provides 628.3 N push and 527.8 N pull at 0.5 MPa, and 879.6 N push at 0.7 MPa. The maximum push force is 128 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
The B02- prefix designates this as AirTAC's welding-industry dedicated variant of the ACQ40X15S, sharing identical specifications and dimensions. It does not feature adjustable air cushions; instead, it uses fixed NBR elastomer bumpers at both ends to absorb end-stop impact.
