The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-100 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 90mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ32X90-100 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend stroke. You can fine-tune the extend end position on the machine itself, yielding a usable extend range of 0-90 mm from a 90 mm full stroke. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays the same, the output force is identical to a standard ACQ of this bore, delivering a push of 402.1 N at 0.5 MPa. The unit includes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and features sensor grooves on the body, though this specific configuration ships without a magnet. It uses a PT1/8 port and a 16 mm piston rod with an M8x1.25 female rod-end thread.

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 clamping extension on a CNC fixture during part-changeover without machining new stop collars or swapping cylinders.
Adjust the push depth of a sealing head on the fly to accommodate varying package sizes on a packaging line.
Set trial end positions for pressing bearings on an assembly line, allowing operators to tweak the extend stroke safely within the 0-90 mm range.
If you need slightly less force, the next bore down is 25 mm, providing 245.4 N push at 0.5 MPa. Stepping up to a 40 mm bore yields 628.3 N push. Choose this 32 mm adjustable model when your setup requires precise extend-position tuning within the 0-90 mm window. If the exact end position is fixed and never changes, a standard ACQ cylinder without the external stop will suffice. When ordering, confirm the 90 mm full stroke, the 100 mm adjustment window, the female rod thread, and whether you need the -S magnet option for position sensing.
Quick checklist
The usable extend range is 0-90 mm (90 mm full stroke minus a 100 mm window). Force is identical to a standard ACQ: push is 402.1 N and pull is 301.6 N at 0.5 MPa, push is 562.9 N at 0.7 MPa, and maximum push is 82 kgf at 1.0 MPa.
An external M12x1.25 threaded adjuster with a lock nut limits only the extend stroke; the retract stroke is unaffected. The adjuster changes stroke length only, not piston area, so force remains unchanged. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion.
