The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-20B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 150mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ32X150-20B is a double-acting JIS compact cylinder with an external stroke adjuster. A threaded stop and lock nut on the rod-end side limits the EXTEND position, providing a usable extend range of 130 to 150 mm. The RETRACT stroke remains completely unaffected. Because the piston area is unchanged, force output is identical to a standard ACQ of the same bore.
This unit features a 150 mm stroke, exceeding the 100 mm standard maximum for a Ø32 bore, making it a long-stroke made-to-order variant. It includes a male M14x1.5 piston rod end for direct load coupling, a fixed NBR elastomer bumper at each end, and a PT1/8 port. The body retains sensor grooves, though this specific SKU ships without a magnet.

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.

Quickly reposition a diverter or pusher on a packaging line to handle different carton widths on the fly.
Safely test varying extend end positions on a light assembly press before finalizing the mechanical hard stop.
When sizing this 32 mm bore, consider the 25 mm bore offering 245.4 N push or the 40 mm bore delivering 628.3 N at 0.5 MPa. If your extend endpoint is fixed and never requires on-machine tweaking, a standard ACQ cylinder will suffice. To order, confirm the 32 mm bore, 150 mm full stroke, 20 mm adjustment window, and the male M14x1.5 rod thread. Note that a plain compact cylinder drifts on air loss; add an external rod lock for fail-safe holding.
Quick checklist
The force is identical to a standard ACQ: 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 130 to 150 mm (a 20 mm window), and the retract stroke is unaffected.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke length only; it does not change the piston area or force. Deceleration is handled by a fixed elastomer bumper, not an adjustable air cushion. The body has sensor grooves, but this model ships without a magnet.
