Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100S 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.

About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100S
The AirTAC ACQJ80X90-100S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. The full stroke is 90 mm, and the -100 window allows the extend length to be shortened by up to 100 mm, yielding a usable extend range of 0-90 mm. The retract stroke remains unaffected by this adjustment. An M20x1.5 external adjuster thread enables precise on-machine end-position tuning without changing parts.
Because the piston area is unchanged, the force output is identical to a standard ACQ of this bore. At 0.5 MPa it delivers 2513.2 N of push force and 2267.8 N of pull force, rising to 3518.5 N push at 0.7 MPa, with a maximum push capacity of 513 kgf at 1.0 MPa. The bore uses a PT3/8 port, a 25 mm piston rod, and fixed elastomer NBR bumpers at both ends for end-of-stroke deceleration. The -S option includes a built-in piston magnet compatible with reed or electronic 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.
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 ACQJ80X90-100S Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC lathe during part-changeover, shortening the extend position to accommodate different workpiece diameters without swapping cylinders.
Carton Sealing Stops
Adjust the platen extend distance on the fly for varying box sizes on a packaging line, ensuring consistent sealing pressure without hardware modifications.
Press Tonnage Testing
Set trial end positions on an assembly press to verify contact and force application before finalizing the stroke length for a new product run.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100S the Right Cylinder?
Selecting this 80 mm bore provides 2513.2 N push force at 0.5 MPa; stepping down to a 63 mm bore yields 1558.6 N push, while stepping up to a 100 mm bore provides 3927.0 N push. If your application never requires altering the extend length, a fixed-stroke ACQ cylinder is sufficient and avoids the external adjuster. When ordering, confirm the 90 mm full stroke, the 100 mm adjustment window, the -S magnet, and the default female M16x2.0 rod-end 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 ACQJ80X90-100S FAQ
The usable extend range is 0-90 mm (full 90 mm stroke minus the 100 mm window). 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 bore is 80 mm, the port is PT3/8, and the adjuster thread is M20x1.5.
No, the adjuster changes the extend stroke length only, meaning the force remains identical to a standard ACQ of the same bore. The cylinder uses fixed elastomer bumpers for deceleration, not adjustable air cushions. Note that a plain ACQ-type cylinder does not hold its load on air loss; for a fail-safe hold, use an external rod lock or pilot-operated check valve.
