Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-100S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-100S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm 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 ACQJ32X100-100S
The AirTAC ACQJ32X100-100S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. With a full stroke of 100 mm and a 100 mm adjustment window, you can fine-tune the usable extend range from 0 up to 100 mm directly on the machine. The retract stroke remains unaffected by this adjustment.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore, yielding 402.1 N push at 0.5 MPa. It includes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The integrated -S piston magnet works seamlessly with both reed and electronic solid-state switches.

| Adjuster thread | M12×1.25 |
| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 ACQJ32X100-100S Is Used
Machining Fixture Stops
Dial in the exact extend position on a milling fixture when raw part thickness varies, avoiding the need to machine custom spacer rings.
Carton Changeover Flaps
Quickly reset the folding arm extension depth during a packaging line product changeover without swapping out the cylinder body.
Press Trial Positions
Establish the optimal end stop for a low-force pressing or testing rig, safely testing multiple stroke depths within the 0 to 100 mm range.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-100S the Right Cylinder?
When sizing this 32 mm bore, moving down to a 25 mm bore drops the push force to 245.4 N at 0.5 MPa, while stepping up to a 40 mm bore increases it to 628.3 N. If your application never requires end-position changes, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable version correctly, confirm the 32 mm bore, 100 mm full stroke, 100 mm 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 ACQJ32X100-100S FAQ
The usable extend range is 0-100 mm (full stroke 100 mm minus a 100 mm window), while the retract stroke is unaffected. It delivers 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa.
No, the external M12x1.25 adjuster only changes the extend stroke length, so force remains identical to a standard ACQ. The cylinder uses a fixed elastomer bumper for deceleration and does not hold the load on air loss; use an external rod lock for fail-safe holding.
