Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-50S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-50S 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 ACQJ32X100-50S
The AirTAC ACQJ32X100-50S is a double-acting JIS compact cylinder featuring an external extend stop. A threaded rod with a lock nut lets you fine-tune the forward end position on the machine, yielding a usable extension range of 50-100 mm. The return stroke remains fixed at its original length.
Because the piston area is unchanged, output thrust equals a standard ACQ of the same bore: 402.1 N push and 301.6 N pull at 0.5 MPa. This 32 mm bore unit includes a piston magnet for position sensing and uses fixed NBR elastomer bumpers at both ends for end-of-travel deceleration.

| 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 |

| 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 ACQJ32X100-50S Is Used
Machining Fixture Changeovers
Quickly dial in the extend stop from 50 to 100 mm when swapping part families on a CNC milling fixture without machining new spacers.
Variable Depth Carton Sealing
Set the precise push distance for different box heights on a packaging line, relying on the 402.1 N thrust to actuate the sealing head.
Assembly Press Trial Positions
Test multiple insertion depths on an electronics assembly press by adjusting the external stop, safely decelerated by the fixed elastomer bumper.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-50S the Right Cylinder?
If your application needs less push power, the 25 mm bore delivers 245.4 N push at 0.5 MPa, while the larger 40 mm bore offers 628.3 N. If the forward position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering this adjustable unit, confirm the 32 mm bore, 100 mm full stroke, 50 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 ACQJ32X100-50S FAQ
It provides 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 100 mm with a 50 mm adjustment window, giving a usable extend range of 50-100 mm.
The M12x1.25 threaded stop limits only the extend length, so output thrust remains identical to a standard ACQ. The unit includes a magnet for reed or solid-state switches, and fixed NBR bumpers handle deceleration rather than adjustable air cushions.
