Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 20mm 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 ACQJ32X20-10B
The AirTAC ACQJ32X20-10B is a double-acting JIS compact cylinder featuring an external male M14x1.5 piston rod and an adjustable extend stop. A threaded bolt with lock nut restricts outward travel, yielding a usable extend range of 10 to 20 mm from the 20 mm full stroke. Retract distance remains completely unaffected.
Because the piston area stays constant, output force matches a standard ACQ exactly, yielding 402.1 N push at 0.5 MPa. The body incorporates fixed NBR elastomer bumpers at both ends and integrated sensor grooves, though this specific unit ships without a magnet.

| 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 ACQJ32X20-10B Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture during setup, allowing rapid accommodation of different part heights without machining new spacers.
Carton Sealing Formers
Adjust the folding platen end-point on the fly during packaging line changeovers to handle varying box widths quickly.
Press Bender Trial Positions
Test intermediate bending depths on a metal forming press by tweaking the external stopper nut instead of swapping the actuator.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-10B the Right Cylinder?
For lighter duties, the 25 mm bore provides 245.4 N push, whereas stepping up to a 40 mm bore yields 628.3 N push at 0.5 MPa. If your machine never requires altering the end position, a fixed-stroke ACQ32X20 is simpler. When ordering this adjustable variant, confirm the 32 mm bore, 20 mm full stroke, 10 mm window, the male rod thread, and whether you need a magnet.
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 ACQJ32X20-10B 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 full stroke is 20 mm, the adjustment window is 10 mm, and the usable extend range is 10-20 mm.
An external M12x1.25 threaded stop with a lock nut physically limits outward travel, so force remains identical to a standard ACQ because piston area is unchanged. The cylinder relies on fixed elastomer bumpers for end-of-stroke deceleration, and this non-magnet version does not contain a sensor magnet.
