The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 90mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ80X90-100 is a double-acting JIS compact cylinder featuring an external extend-stroke stop. A threaded M20x1.5 adjuster and lock nut let you set the forward end position from 0 up to 90 mm directly on your equipment. The return stroke remains fixed at the 90 mm full length. Because the piston area stays constant, output force equals a standard ACQ of this bore.
This 80 mm bore unit pushes 2513.2 N and pulls 2267.8 N at 0.5 MPa. It uses a 25 mm rod with a female M16x2.0 end, a PT3/8 port, and fixed NBR elastomer bumpers at both ends rather than adjustable pneumatic cushions. The body includes magnetic-switch grooves, though this specific SKU ships without a magnet.

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 | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 CNC mill fixture by turning the external stop, accommodating raw part variations without remachining jaws.
Adjust the extend length of a sorting gate on a packaging line to handle different carton widths on the fly, avoiding mechanical teardown.
Test multiple working depths on an assembly press by fine-tuning the rod extension, finding the optimal engagement point before finalizing hard stops.
Select this 80 mm bore if your setup requires varying the extend endpoint within a 0 to 90 mm window without swapping cylinders. Push force is 2513.2 N at 0.5 MPa; dropping to a 63 mm bore drops push to 1558.6 N, while stepping up to 100 mm yields 3927.0 N. If you never need to alter the forward stroke, a fixed ACQ cylinder provides identical power in a simpler package. Verify your ordering code for the 90 mm full stroke, 100 mm window, female rod thread, and PT3/8 porting.
Quick checklist
At 0.5 MPa it provides 2513.2 N push and 2267.8 N pull force, and 3518.5 N push at 0.7 MPa. Maximum push is 513 kgf at 1.0 MPa. The usable extend range is 0 to 90 mm, set via a 100 mm adjustment window, while the retract stroke stays fixed at 90 mm.
An external M20x1.5 threaded stop with a lock nut limits the forward extension, changing only the stroke length and not the piston area, so force remains identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers at both ends, not adjustable air cushions. Note that this model ships without a sensor magnet.
