Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-50S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 60mm 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 ACQJ40X60-50S
The ACQJ40X60-50S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You get a usable extend range of 10-60 mm, achieved by subtracting the 50 mm adjustment window from the 60 mm full stroke. The retract stroke remains completely unaffected by this mechanism. A built-in piston magnet (-S) is included for position sensing.
Because the piston area stays constant, the output force is identical to a standard ACQ of the same bore. The 40 mm bore generates a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. It utilizes a 16 mm rod, a PT1/8 port, and fixed elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions.

| 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X60-50S Is Used
Machine Tending Setup
Dial in the exact extend position from 10 to 60 mm during initial machine commissioning without machining custom spacers.
Product Changeover Stops
Adapt the extend end stop on packaging lines quickly when switching to a different product length or fixture height.
Prototype Positioning
Test various extend end points on a new assembly rig to find the optimal travel distance before finalizing the design.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-50S the Right Cylinder?
If you need less push force at 0.5 MPa, the 32 mm bore provides 402.1 N. If your application requires more power, the 50 mm bore yields 981.8 N. Choose this adjustable model when you need on-the-fly end-position tuning; if a fixed 60 mm extend position is always required, a standard ACQ cylinder will suffice. To order, confirm the 40 mm bore, 60 mm full stroke, 50 mm window, the -S magnet option, and the 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 ACQJ40X60-50S FAQ
The usable extend range is 10-60 mm (60 mm full stroke minus the 50 mm window). It delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The external adjuster features an M12x1.25 thread.
No, the adjuster only changes the extend stroke length, meaning the force remains identical to a standard ACQ because the piston area is unchanged. The retract stroke is unaffected. The cylinder uses fixed elastomer bumpers for deceleration, and the -S magnet works with both reed and solid-state electronic switches.
