The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-40S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 35mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The ACQJ32X35-40S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You get a 0-35 mm usable extend range (35 mm full stroke minus the 40 mm window) without changing parts. The retract stroke remains unaffected.
Because the piston area stays the same, the output force is identical to a standard ACQ of this bore: 402.1 N push and 301.6 N pull at 0.5 MPa. The 32 mm bore uses a PT1/8 port, a 16 mm rod, and fixed NBR elastomer bumpers at each end. The -S magnet works with reed or solid-state switches.

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.
| 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.

Dial in the extend position from 0 to 35 mm on a CNC lathe loader without machining new stop collars.
Shift the extend endpoint up to 40 mm during packaging line format changes to accommodate different carton widths.
Test various extend endpoints on a lab assembly rig to find the exact 32 mm bore push location before finalizing the mechanical design.
If you need less force, the 25 mm bore delivers 245.4 N push @0.5 MPa, while the 40 mm bore gives 628.3 N push @0.5 MPa for heavier loads. Choose this adjustable model only if your end position requires on-the-fly tuning; a fixed-stroke ACQ suffices for static stops. Confirm your ordering code with the 32 mm bore, 35 mm full stroke, 40 mm window, -S magnet, and female M8x1.25 rod thread.
Quick checklist
It delivers 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 usable extend range is 0-35 mm via a 40 mm window. It uses a PT1/8 port, a 16 mm rod, and an M12x1.25 external adjuster thread.
No, the external stop only changes the extend length, so force remains identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. Note that a plain compact cylinder will not hold a load if air pressure drops; use an external rod lock for fail-safe holding.
