Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-30S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-30S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 75mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-30S
The AirTAC ACQJ80X75-30S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend stroke from 45 to 75 mm directly on your machinery, while the retract stroke remains completely unaffected. Because the piston area is unchanged, output force is identical to a standard ACQ of this bore.
This 80 mm bore unit features a 25 mm piston rod, PT3/8 porting, and a female M16x2.0 rod-end thread. It includes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration. The -S suffix indicates a built-in piston magnet, allowing seamless integration with reed or electronic solid-state switches via the integrated sensor grooves.

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.
Theoretical Output Force (Ø80mm)
| 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.

Where the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-30S Is Used
Machining Center Clamping
Dial in the exact clamping reach on CNC fixtures by shortening the extend stroke from 75 mm down to 45 mm without swapping out cylinder hardware.
Product Changeover Diverters
Adjust the extend stop on packaging lines to accommodate varying carton sizes, using the external M20x1.5 lock nut to set the new end position rapidly.
Press Trial Positions
Test different end-of-stroke locations on assembly presses safely, relying on the fixed elastomer bumper to decelerate the rod near the final position.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-30S the Right Cylinder?
Selecting this 80 mm bore provides a push force of 2513.2 N and a pull force of 2267.8 N at 0.5 MPa. If your application requires less thrust, stepping down to a 63 mm bore yields 1558.6 N of push force, whereas moving up to a 100 mm bore provides 3927.0 N. A fixed-stroke ACQ is sufficient if your end position never varies, but this adjustable model is necessary for setups requiring on-the-fly end-position tuning. When ordering, verify the 75 mm full stroke, 30 mm adjuster window, -S magnet requirement, and the default female rod thread.
Quick checklist
- ✓ Need on-machine end-position tuning?
- ✓ Full stroke and adjust window (mm)
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the adjuster nut after setting the stop.
- check The stop limits the EXTEND stroke only.
- check Avoid side load on the short piston rod.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-30S FAQ
At 0.5 MPa, the push force is 2513.2 N and the pull force is 2267.8 N. At 0.7 MPa, the push force is 3518.5 N, with a maximum push capacity of 513 kgf at 1.0 MPa. The full stroke is 75 mm, and with the 30 mm adjustment window, the usable extend range is 45 to 75 mm.
No, the external adjuster only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The adjuster uses an M20x1.5 thread with a lock nut, and the cylinder relies on a fixed elastomer bumper rather than an adjustable air cushion. Note that a plain cylinder does not hold its load on air loss, so an external rod lock is needed for fail-safe holding.
