The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X250-100 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 250mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The ACQJ32X250-100 is a double-acting JIS compact cylinder built for applications requiring precise extend-position tuning. It features a 32mm bore and a 250mm full stroke. An external M12x1.25 threaded stop with a lock nut lets you shorten the extend stroke by up to 100mm, yielding a usable extend range of 150-250mm. The retract stroke remains completely unaffected. Because the piston area is unchanged, output force is identical to a standard ACQ of this bore.
This unit is a long-stroke made-to-order variant, exceeding the 100mm standard maximum for a 32mm bore. It delivers 402.1N push and 301.6N pull force at 0.5 MPa, operating at speeds of 30-500 mm/s. The body includes sensor grooves for reed or solid-state switches, though this specific configuration ships without a magnet. Deceleration is handled by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions.

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.

Accommodates varying raw material lengths on a CNC fixture by dialing the extend stop back from 250mm down to 150mm without swapping hardware.
Quickly resets a sorting diverter arm position during product family transitions using the external M12x1.25 adjuster to match new carton depths.
Safely probes optimal end-of-stroke locations for a 32mm bore pressing operation during prototype runs before finalizing mechanical hard stops.
When sizing this actuator, consider the 402.1N push force at 0.5 MPa. If your application requires less force, stepping down to a 25mm bore provides 245.4N push, while moving up to a 40mm bore yields 628.3N push. A standard fixed-stroke ACQ is sufficient if your end position never varies. For ordering, confirm the 32mm bore, 250mm full stroke, 100mm adjuster window, PT1/8 porting, and the default female M8x1.25 rod-end thread. Remember to add the -S magnet option if you need electronic or reed switch sensing.
Quick checklist
This 32mm bore cylinder provides 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 250mm, but the external adjuster allows you to shorten the extend stroke by up to 100mm, creating a usable extend range of 150-250mm.
No, the adjuster only limits stroke length, so force remains identical to a standard ACQ. The retract stroke is unaffected. End-of-travel energy is absorbed by fixed NBR elastomer bumpers rather than adjustable air cushions. Note that this model ships without a sensor magnet, and a plain ACQ will drift if air pressure is lost, requiring an external rod lock for fail-safe load holding.
