Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 50mm 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 ACQJ32X50-10S
The AirTAC ACQJ32X50-10S is a double-acting JIS compact cylinder with an external extend stop, letting you fine-tune the stroke on the machine. The 10 mm adjustment window provides a usable extend range of 40-50 mm, while the retract stroke remains unaffected. A lock nut secures the M12x1.25 adjuster thread.
Because the piston area is unchanged, force output is identical to a standard ACQ bore 32 cylinder. The unit delivers 402.1 N push and 301.6 N pull at 0.5 MPa. It features fixed NBR elastomer bumpers for end-of-stroke deceleration and a built-in magnet for position sensing.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 50 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 ACQJ32X50-10S Is Used
Machining Fixture Stops
Dial in the exact 40-50 mm extend position during CNC fixture setup to accommodate varying raw casting dimensions without machining custom stop blocks.
Packaging Machine Changeover
Rapidly adjust the extend end point on a sealing head when switching between different carton sizes on a high-speed packaging line.
Assembly Press Trials
Test different insertion depths on an electronics assembly press by turning the external stop screw, finding the optimal end position before finalizing the mechanical setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-10S the Right Cylinder?
For lower force requirements, the ACQJ25 bore yields a 245.4 N push at 0.5 MPa, whereas stepping up to the ACQJ40 bore provides 628.3 N. If your end position never varies, a fixed-stroke ACQ32X50 is simpler and sufficient. When ordering, confirm the 32 mm bore, 50 mm full stroke, 10 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 ACQJ32X50-10S FAQ
The usable extend range is 40-50 mm (50 mm full stroke minus the 10 mm window). Force is identical to a standard ACQ32: 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 external threaded stop with a lock nut limits the extend distance without altering the piston area, so force remains unchanged. Retract stroke is unaffected. The cylinder uses fixed NBR elastomer bumpers at each end for deceleration rather than adjustable air cushions, and the built-in magnet works with reed or electronic solid-state switches.
