The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 80mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ32X80-30 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 50 mm up to the full 80 mm directly on your equipment, while the retract stroke remains unaffected. It features a 32 mm bore, a 16 mm piston rod, and a PT1/8 port.
Because the adjuster only alters stroke length and not piston area, output force stays identical to a standard ACQ of this bore. The cylinder delivers 402.1 N push and 301.6 N pull at 0.5 MPa, with a maximum push capacity of 82 kgf at 1.0 MPa. It relies on fixed NBR elastomer bumpers at each end for end-of-stroke deceleration 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.

Dial in the extend position from 50 to 80 mm on a CNC machining fixture to accommodate raw part tolerances without machining new spacers.
Rapidly adjust the rod extension end point during packaging line format changeovers to handle different carton depths on the fly.
Probe trial end positions on an electronics assembly press, tweaking the stroke by up to 30 mm to find the optimal insertion depth.
If you need slightly less thrust, the 25 mm bore yields 245.4 N push at 0.5 MPa, whereas stepping up to the 40 mm bore provides 628.3 N. A fixed-stroke ACQ is sufficient if your end position never requires shifting. When ordering this adjustable variant, confirm the 32 mm bore, 80 mm full stroke, 30 mm window, female M8x1.25 rod-end thread, and whether you need the -S magnet option for position sensing.
Quick checklist
It provides 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 full stroke is 80 mm with a 30 mm window, allowing the usable extend range to be adjusted from 50 mm to 80 mm.
An M12x1.25 threaded stop with a lock nut mechanically limits the extend length, meaning force remains identical to a standard ACQ since piston area is unchanged. Deceleration relies on fixed elastomer bumpers, not adjustable air cushions, and the body includes sensor grooves for adding reed or solid-state switches if you specify the magnet option.
