Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-100SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-100SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 150mm 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 ACQJ40X150-100SB
The ACQJ40X150-100SB is a double-acting, single-rod JIS compact cylinder engineered for on-site stroke adjustment. It features a 150mm total stroke and a 100mm adjustment window, allowing the extend end position to be precisely set anywhere from 50mm up to the full 150mm. Because the external threaded stop merely limits extension travel without altering piston area, output force remains identical to a standard ACQ of the same bore. The retract stroke remains completely unaffected.
This made-to-order long-stroke variant exceeds the standard 100mm maximum for the 40mm bore size. It includes a built-in piston magnet for electronic or reed switch sensing, a male M14x1.5 piston rod end for direct mounting, and fixed NBR elastomer bumpers at both ends. Operating pressure spans 0.15 to 1.0 MPa, with a PT1/8 port ensuring reliable pneumatic supply.

| 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 ACQJ40X150-100SB Is Used
Machining Fixture Stops
Dial in the exact clamping extension on CNC fixtures during product changeovers without machining new stop collars.
Diverter Gate Positioning
Adjust the pusher arm reach on packaging conveyor lines to handle varying box widths on the fly.
Assembly Press Trials
Safely test and incrementally increase the extend end position on automated assembly presses before finalizing the stroke.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-100SB the Right Cylinder?
Selecting this 40mm bore yields a push force of 628.3N at 0.5MPa. If your application requires less power, the 32mm bore provides 402.1N; for heavier loads, the 50mm bore offers 981.8N. If the 150mm extension is fixed and never needs shortening, a standard ACQ40X150 cylinder is sufficient. To order, confirm the 40mm bore, 150mm full stroke, 100mm window, along with the S magnet and B male rod options.
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 ACQJ40X150-100SB FAQ
The usable extend range is 50-150mm. Force is identical to a standard ACQ40: push is 628.3N and pull is 527.8N at 0.5MPa, push is 879.6N at 0.7MPa, and maximum push is 128kgf at 1.0MPa.
An external M12x1.25 threaded stop with a lock nut limits extension travel without changing piston area, so force is unchanged. The retract stroke is unaffected. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions, so external shock absorbers are advised for high-energy loads.
