The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-75B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 100mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ32X100-75B is a double-acting JIS compact cylinder featuring a 32mm bore and a 100mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 25-100mm without changing parts. The retract stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of this size, delivering 402.1N push and 301.6N pull at 0.5MPa.
This unit includes a male M14x1.5 piston rod end for direct load coupling and uses an M12x1.25 adjuster thread. It features a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The body retains magnetic-switch grooves for position sensing, though this specific configuration ships without a magnet. Operating pressure spans 0.15-1.0MPa with a speed range of 30-500mm/s.

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 exact 25 to 100mm extend position during new product changeovers without machining custom stop spacers.
Fine-tune the end-of-stroke contact point on automated lathes to accommodate varying raw material lengths.
Adjust the push depth on-the-fly to handle different carton sizes while keeping the full retract stroke intact.
When sizing this 32mm bore, consider the adjacent options: a 25mm bore yields 245.4N push at 0.5MPa, while a 40mm bore provides 628.3N. This model delivers 402.1N push and 301.6N pull at 0.5MPa, peaking at 562.9N push at 0.7MPa with a maximum push of 82kgf at 1.0MPa. If your extend position never needs tuning, a fixed-stroke ACQ suffices. To order this version, confirm the 32mm bore, 100mm full stroke, 75mm adjustment window, the male M14x1.5 rod thread, and that no magnet is required.
Quick checklist
The usable extend range is 25-100mm. It generates 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The force is identical to a standard ACQ of the same bore.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke, while the retract stroke is unaffected. A fixed NBR bumper decelerates the piston near stroke ends. The cylinder does not hold loads on air loss; for fail-safe holding, use an external rod lock.
