The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 60mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ40X60-30 is a double-acting JIS compact cylinder featuring an external extend stop. A threaded screw with a lock nut limits the outward travel, letting you set the usable extend range from 30 up to 60 mm directly on your equipment. The retract stroke remains fixed at 60 mm.
Because the piston area stays the same, output force equals a standard ACQ of this bore. At 0.5 MPa it pushes 628.3 N and pulls 527.8 N. This variant includes a 16 mm rod, an M8x1.25 female rod end, PT1/8 port, and fixed NBR elastomer bumpers 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 |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 30 to 60 mm clamping reach on a CNC fixture during part-changeover without machining new spacers.
Fine-tune the folding arm extension on a packaging line to accommodate different box depths rapidly.
Set trial end positions for pressing bearings on an assembly line, tweaking the outward stroke in millimeters.
If 527.8 N pull at 0.5 MPa is insufficient, step up to the 50 mm bore for 824.6 N; if you need less force, the 32 mm bore provides 301.6 N. Choose this 40 mm bore when your application needs roughly 628 N push alongside on-machine extend tuning. If the outward position never varies, a fixed-stroke ACQ cylinder is adequate. When ordering, confirm the 60 mm full stroke, 30 mm window, PT1/8 porting, and female M8x1.25 rod end.
Quick checklist
It delivers 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The usable extend range is 30 to 60 mm, created by a 30 mm adjustment window on the 60 mm full stroke.
An M12x1.25 threaded adjuster with a lock nut mechanically limits the extend stroke, so force remains identical to a standard ACQ. The retract stroke is unaffected. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
