The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-40B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 60mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ32X60-40B is a double-acting JIS compact cylinder featuring a 32 mm bore and a 60 mm full stroke. An external M12x1.25 threaded stop with a lock nut limits the extend end position, giving a usable outward range of 20 to 60 mm. The retract stroke remains unaffected by this adjustment.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 402.1 N push at 0.5 MPa. The body includes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and features magnetic-switch grooves, though this specific unit ships without a magnet. The male M14x1.5 rod-end thread couples directly to your load.

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 reach on a machining fixture during setup, compensating for varying part thicknesses without machining new spacers.
Adjust the extend position of a conveyor diverter gate on the fly during a packaging line product changeover to handle different carton lengths.
Test and set trial end positions on an assembly press, fine-tuning the 20 to 60 mm outward travel to find the optimal pressing depth.
For 0.5 MPa push requirements, the 25 mm bore yields 245.4 N while the 40 mm bore provides 628.3 N, making this 32 mm bore a strong middle option at 402.1 N. If your extend distance never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 32 mm bore, 60 mm full stroke, 40 mm adjuster window, the male rod thread, and whether you need the -S magnet option.
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 60 mm with a 40 mm adjustment window, yielding a usable extend range of 20 to 60 mm.
An external M12x1.25 threaded stop with a lock nut mechanically limits how far the rod extends, shortening the outward stroke without changing the piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected, and a fixed elastomer bumper decelerates the load at each end.
