The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X60-75 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 60mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ80X60-75 is a double-acting JIS compact cylinder featuring an external M20x1.5 threaded stop with a lock nut to limit the extend end position. You can tune the usable extend range from 0 up to 60 mm directly on your machinery without swapping parts, while the retract stroke remains completely unaffected.
Because the adjustment only alters travel length and not piston area, output force matches a standard ACQ exactly. At 0.5 MPa it delivers 2513.2 N of push force and 2267.8 N of pull force, peaking at a 513 kgf maximum push at 1.0 MPa. The body incorporates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions, and includes sensor grooves for adding reed or solid-state switches.

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 lathe during setup. The external stop lets operators compensate for varying raw material thicknesses without reprogramming the pneumatic valves.
Adjust the stroke length on a packaging line diverter to handle different carton widths. The lock nut secures the new extend position quickly during product changeovers.
Establish trial end positions for pressing bearings on an assembly line. The 0 to 60 mm usable range allows fine-tuning the press depth before finalizing the mechanical setup.
Choosing this 80 mm bore provides 2513.2 N push at 0.5 MPa; stepping down to a 63 mm bore drops push to 1558.6 N, while a 100 mm bore raises it to 3927.0 N. If your application never requires modifying the end position, a fixed-stroke ACQ cylinder is simpler and sufficient. When ordering, verify the 60 mm full stroke, the 75 mm adjustment window, the female M16x2.0 rod end, and note this specific configuration ships without a magnet.
Quick checklist
It provides 2513.2 N push and 2267.8 N pull at 0.5 MPa, 3518.5 N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. The full stroke is 60 mm with a 75 mm window, allowing the extend stroke to be adjusted from 0 to 60 mm.
An external M20x1.5 threaded screw with a lock nut mechanically limits the extend travel, leaving the retract stroke unaffected. Force remains identical to a standard ACQ because the piston area is unchanged. The cylinder uses fixed elastomer bumpers, not air cushions, and will not hold a load if air pressure is lost; use an external rod lock for fail-safe holding.
