Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X50-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X50-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X50-10B
The AirTAC ACQJ40X50-10B is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend stroke. You can fine-tune the extend end position on the machine without changing parts, yielding a usable extend range of 40-50mm (the 50mm full stroke minus up to a 10mm window). The retract stroke remains completely unaffected. Because the piston area is unchanged, the force output is identical to a standard ACQ of this bore.
This model features a male M14x1.5 piston rod thread that couples directly to your load, alongside a PT1/8 port and a 16mm rod diameter. It includes fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The body retains magnetic-switch grooves, though this specific configuration ships without the -S magnet. Operating pressure spans 0.15-1.0 MPa, with a maximum push force of 128 kgf at 1.0 MPa.

| 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 ACQJ40X50-10B Is Used
Product Changeover Stops
Set precise extend endpoints during packaging format changes, allowing rapid 40-50mm adjustments without machining new stop collars.
Fixture Position Tuning
Dial in the exact clamping extension on machining fixtures to accommodate varying part tolerances directly on the equipment.
Assembly Press Calibration
Establish trial end positions for pressing sub-components, tweaking the stroke within the 10mm window to perfect the insertion depth.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X50-10B the Right Cylinder?
If you need less force, the 32mm bore variant provides 402.1N push at 0.5 MPa, whereas stepping up to the 50mm bore yields 981.8N push. A standard fixed-stroke ACQ40 is sufficient if your extend end position never requires adjustment. When ordering, verify the 40mm bore, 50mm full stroke, 10mm adjustable window, the male M14x1.5 rod thread, and the absence of 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 ACQJ40X50-10B FAQ
The usable extend range is 40-50mm (50mm full stroke minus the 10mm window). Force is identical to a standard ACQ40: 628.3N push and 527.8N pull at 0.5 MPa, 879.6N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The retract stroke is unaffected.
An external M12x1.25 threaded stop and lock nut mechanically limits how far the rod extends, altering stroke length only without changing piston area or force. The cylinder uses fixed NBR elastomer bumpers at each end for deceleration instead of adjustable air cushions. Note that a plain ACQ-type does not hold its load on air loss; use an external rod lock for fail-safe holding.
