About the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X100S
The AirTAC B02-ACQ40X100S is a double-acting, single-rod JIS compact cylinder engineered for welding-line automation. The B02- prefix marks this as a welding-industry dedicated variant of the base ACQ40X100S, meaning it is mechanically identical to the standard model but designated for fixturing and clamping in robotic welding cells. It delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa.
This 40 mm bore unit features a 16 mm piston rod and utilizes a short C-clip and riveted body construction to drastically reduce axial mounting depth compared to round-body alternatives. Because it includes the -S magnet, you can mount AirTAC reed or electronic switches directly into the body grooves for end-of-stroke detection. The cylinder relies on a fixed NBR elastomer bumper at each end to absorb impacts rather than an adjustable air cushion.

Where the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X100S Is Used
Robot Welding Cell Clamping
Secures mild steel stampings inside a robotic MIG welding cell, using its 628.3 N push force at 0.5 MPa to hold panels firmly against locators while maintaining a low profile behind the torch clearance zone.
Spot Welding Gun Actuation
Drives the lower arm of a resistance spot welding gun on an automotive body-in-white line, where the 100 mm stroke provides full electrode opening clearance for robotic part loading.
Weld Fixture Ejection
Ejects completed tubular weldments from a multi-station fixture table, utilizing the 527.8 N retract force at 0.5 MPa to pull a pin or kick-out plate reliably after the weld cools.
Is the Airtac B02-ACQ Ultra-Thin Welding Special Cylinder B02-ACQ40X100S the Right Cylinder?
When sizing this model, stepping down to a 32 mm bore yields 402.1 N of push force at 0.5 MPa, while stepping up to a 50 mm bore provides 981.8 N. This 40 mm option sits in the middle, offering 879.6 N of extension force at 0.7 MPa with a maximum push capacity of 128 kgf at 1.0 MPa. Operating speed ranges from 30-500 mm/s.
For your ordering essentials, this configuration features a 100 mm stroke (the maximum standard stroke for this bore), a PT1/8 port, a female M8x1.25 rod-end thread, and the built-in -S magnet. Note that a plain compact cylinder like this will drift and cannot hold a load if air pressure is lost or the valve is centered; achieving a fail-safe hold in a welding fixture requires adding 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-ACQ40X100S FAQ
This 40 mm bore cylinder provides a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push force is 879.6 N. The maximum push force is 128 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, and the standard speed range is 30-500 mm/s.
The B02- prefix designates this as a welding-industry dedicated variant of the ACQ40X100S; it is mechanically identical to the base cylinder with no special seals or coatings. Instead of an adjustable air cushion, it uses a fixed NBR elastomer bumper at each end to absorb the impact. For high-energy or high-speed welding operations, you should slow the approach or add an external shock absorber.
