Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-100S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-100S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 200mm 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 ACQJ40X200-100S
The ACQJ40X200-100S is a double-acting JIS compact cylinder built for applications requiring a long 200mm stroke with on-machine extend tuning. An external M12x1.25 threaded stop and lock nut lets you set the extend end position anywhere within a 100 to 200mm usable range without swapping parts. The retract stroke remains fixed at the full 200mm. This unit features a 16mm piston rod, a PT1/8 port, and a female M8x1.25 rod-end thread.
Because the adjuster only limits travel, the piston area stays the same, meaning force is identical to a standard ACQ of this bore. You get 628.3N push and 527.8N pull at 0.5MPa, rising to 879.6N push at 0.7MPa, with a maximum push capacity of 128kgf at 1.0MPa. This made-to-order 200mm variant exceeds the standard 100mm maximum for a 40mm bore, and includes a -S piston magnet compatible with reed or solid-state electronic switches. Deceleration relies on fixed NBR elastomer bumpers at both ends rather than adjustable air cushions.

| 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 ACQJ40X200-100S Is Used
Long-Reach Sorting Diverter
Ideal for packaging lines needing a 200mm reach to push cartons into secondary lanes, with the 100mm window allowing quick stop repositioning for varying box sizes.
Product Changeover Stops
Use on assembly fixtures where the extend endpoint must shift between product families, enabling operators to dial in the exact 100-200mm position via the M12x1.25 adjuster.
Extended Stroke Clamping
Suits automated welding or machining cells requiring a long approach to clamp oversized workpieces, relying on the 628.3N push force at 0.5MPa to secure the part.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-100S the Right Cylinder?
Selecting this model requires confirming the 40mm bore, 200mm full stroke, and 100mm adjustment window alongside the -S magnet and female M8x1.25 rod thread. If your extend requirement never varies, a fixed-stroke ACQ suffices and avoids the external adjuster overhang. For sizing context, stepping down to a 32mm bore yields 402.1N push at 0.5MPa, while stepping up to a 50mm bore provides 981.8N push at 0.5MPa. Keep in mind that a standard ACQ-type does not hold its load on air loss; for fail-safe holding, add an external rod lock or pilot-operated check valve.
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 ACQJ40X200-100S FAQ
This cylinder 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 200mm, but the external stop provides a 100mm adjustment window, resulting in a usable extend range of 100-200mm.
No, the adjuster only shortens the extend travel; force remains identical to a standard ACQ because the piston area is unchanged. Deceleration is handled by fixed NBR elastomer bumpers at each end, not adjustable air cushions, so external shock absorbers are recommended for high-speed or high-energy loads.
