Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-50S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 100mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-50S
The ACQJ40X100-50S is a double-acting JIS compact cylinder featuring a 40mm bore and a 100mm full stroke. An external M12x1.25 threaded stop with a lock nut limits the extend end position, giving you a usable extend range of 50 to 100mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, output force equals a standard ACQ of the same bore, delivering 628.3N push and 527.8N pull at 0.5MPa. The -S suffix indicates a built-in piston magnet compatible with reed or solid-state electronic switches. Fixed NBR elastomer bumpers at both ends handle end-of-stroke deceleration.

Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; the piston area — and therefore the force — is the same as a standard ACQ of this bore. Adjustable window options: 10/20/30/40/50/75/100 mm.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Force equals a standard ACQ of the same bore — the adjuster changes stroke length, not piston area. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-50S Is Used
Machining Fixture Stops
Dial in the exact extend position for varying raw material blanks on a CNC milling fixture without swapping out cylinder hardware.
Packaging Changeover
Quickly reset the product pusher end point on a packaging line when transitioning between different carton widths.
Assembly Press Trials
Safely test intermediate extend end positions during light-duty electronic component insertion before locking the final depth.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-50S the Right Cylinder?
If 527.8N pull at 0.5MPa is insufficient, step up to the 50mm bore (824.6N pull); if you need less force, the 32mm bore provides 301.6N pull. A standard fixed-stroke ACQ suffices if your extend end position never requires on-machine tuning. When ordering this adjustable version, confirm the 40mm bore, 100mm full stroke, 50mm window, the -S magnet option, and the default female M8x1.25 rod-end thread.
Quick checklist
- ✓ Need on-machine end-position tuning?
- ✓ Full stroke and adjust window (mm)
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the adjuster nut after setting the stop.
- check The stop limits the EXTEND stroke only.
- check Avoid side load on the short piston rod.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-50S FAQ
It delivers 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The full stroke is 100mm with a 50mm window, allowing the usable extend range to be adjusted from 50mm up to 100mm.
No. The external M12x1.25 threaded stop only limits the extend length, so retract remains unaffected and force is identical to a standard ACQ. The cylinder uses fixed elastomer bumpers rather than adjustable air cushions, and the -S magnet works with both reed and electronic switches.
