Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-30S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-30S 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 ACQJ40X100-30S
The AirTAC ACQJ40X100-30S is a double-acting JIS compact cylinder with a 100mm full stroke and a 30mm external adjustment window, allowing the extend end position to be fine-tuned directly on the machine from 70mm to 100mm without swapping parts. The retract stroke remains completely unaffected by this mechanism. An external M12x1.25 threaded stop with a lock nut limits the outward travel, and the built-in piston magnet (-S) supports both reed and electronic solid-state switches.
Because the adjuster only restricts travel length and leaves piston area unchanged, force output is identical to a standard ACQ of the same bore, delivering 628.3N push and 527.8N pull at 0.5MPa. The cylinder body features fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. With a 16mm piston rod, PT1/8 porting, and a female M8x1.25 rod-end thread, this unit operates efficiently within a 0.15-1.0MPa pressure range.

| Rod thread | M8×1.25 (F) / M14×1.5 (B) |
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 ACQJ40X100-30S Is Used
Multi-Product Changeover Stops
Dial in the extend stop from 70 to 100mm during production line changeovers to accommodate varying part widths without replacing the cylinder.
Packaging Fixture Setup
Fine-tune the clamping end position on packaging machinery to safely seat different carton sizes without reprogramming the motion controller.
Trial End Positions
Establish optimal feeding distances on a new assembly machine by testing intermediate extend lengths before locking the nut for a permanent setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-30S the Right Cylinder?
If you need slightly less thrust, the 32mm bore variant provides 402.1N push at 0.5MPa, whereas stepping up to the 50mm bore yields 981.8N push for heavier loads. A fixed-stroke standard ACQ cylinder is sufficient if your extend end position never requires field adjustments. When ordering this adjustable model, verify the 40mm bore, 100mm full stroke, 30mm window, the -S magnet option, and your required 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 ACQJ40X100-30S FAQ
The usable extend range is 70-100mm (the 100mm full stroke minus the 30mm window). Force is identical to a standard ACQ: 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.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke length only; it does not change piston area or force. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions, so for high-energy loads you should slow the approach or add an external shock absorber.
