Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20S 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 ACQJ32X100-20S
The AirTAC ACQJ32X100-20S is a double-acting, single-rod JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. The full stroke is 100 mm, and the 20 mm adjustment window allows you to fine-tune the usable extend range from 80 mm up to 100 mm on the machine without changing parts. The retract stroke remains unaffected by this mechanism.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore. At 0.5 MPa, it delivers 402.1 N of push force and 301.6 N of pull force. The unit features a 16 mm rod, a PT1/8 port, an M12x1.25 adjuster thread, and fixed elastomer bumpers at both ends. The built-in magnet (-S) is compatible with reed and solid-state sensors.

| 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 ACQJ32X100-20S Is Used
Machining Fixture Stops
Dial in the exact 80-100 mm extend position during CNC fixture changeovers without machining custom spacers.
Carton Folding Arms
Modify the extend reach on the fly when switching carton sizes on a packaging line, keeping motion profiles intact.
Assembly Press Trial
Safely test multiple extend endpoints on an assembly press to find the optimal engagement distance before final lock-down.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20S the Right Cylinder?
When sizing this 32 mm bore actuator, consider the neighbouring bores: a 25 mm bore yields 245.4 N push at 0.5 MPa, while a 40 mm bore yields 628.3 N push. If your extend endpoint is fixed and never varies, a standard non-adjustable ACQ cylinder is sufficient. To order, confirm the 32 mm bore, 100 mm full stroke, 20 mm window, the -S magnet, 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 ACQJ32X100-20S FAQ
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. The usable extend range is 80-100 mm (100 mm full stroke minus up to 20 mm).
No. The external M12x1.25 threaded stop only limits how far the rod extends, leaving the retract stroke unaffected. The force remains identical to a standard ACQ because the piston area is unchanged, and fixed elastomer bumpers decelerate the load at both ends.
