Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-50
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-50 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 ACQJ32X100-50
The AirTAC ACQJ32X100-50 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the EXTEND end position. You get a usable extend range of 50 to 100 mm (full stroke 100 mm minus up to 50 mm), while the RETRACT stroke remains completely unaffected. Because the piston area stays constant, the output force is identical to a standard ACQ of this bore.
This 32 mm bore pneumatic actuator features a 16 mm rod, a PT1/8 port, and a female M8x1.25 rod-end thread. The external adjuster uses an M12x1.25 thread. It includes fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, and the body features integrated magnetic-switch grooves for adding sensors later. Operating pressure spans 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.

| Bore size | Ø32 mm |
| Full stroke | 100 mm |
| 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ32X100-50 Is Used
Machining Fixture Stops
Dial in the exact extend position from 50 to 100 mm on a milling fixture to accommodate different part heights without machining new spacers.
Product Changeover Guides
Shift the extend end stop on a packaging line conveyor guide to accept a new carton size, using the lock nut to secure the new position quickly.
Assembly Press Trials
Test various end positions on an assembly press to find the optimal engagement depth before finalizing the mechanical setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-50 the Right Cylinder?
If you need less push force, the 25 mm bore yields 245.4 N push @0.5 MPa, whereas stepping up to a 40 mm bore provides 628.3 N. Choose this adjustable model when your end position needs frequent tweaking; if the stroke never varies, a fixed ACQ cylinder is simpler. Confirm your bore (32), full stroke (100), adjustment window (-50), rod thread (female M8x1.25), and note this unit ships without a magnet (-S required for sensors).
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 ACQJ32X100-50 FAQ
The force is identical to a standard ACQ: 402.1 N push and 301.6 N pull @0.5 MPa, 562.9 N push @0.7 MPa, and a maximum push of 82 kgf @1.0 MPa. The usable extend range is 50-100 mm (100 mm full stroke minus the 50 mm window).
An external M12x1.25 threaded stop with a lock nut limits how far the rod extends; turning the screw shortens the extend stroke. The retract stroke is unaffected, and force remains unchanged because piston area is constant. The cylinder uses fixed NBR elastomer bumpers at each end, not adjustable air cushions.
