Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-20
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-20 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 45mm 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 ACQJ80X45-20
The AirTAC ACQJ80X45-20 is a double-acting JIS compact cylinder featuring an external extend-stop mechanism. An M20x1.5 threaded adjuster with a lock nut lets you fine-tune the forward end position on the machine, yielding a usable extend range of 25 to 45 mm from the 45 mm full stroke. The return stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore, delivering 2513.2 N push at 0.5 MPa. The 80 mm bore utilizes a 25 mm rod, a PT3/8 port, and fixed NBR elastomer bumpers at both ends rather than adjustable pneumatic cushions. This model ships without a magnet, though the body retains magnetic-switch grooves for adding sensors later.

| Rod thread | M16×2.0 (F) / M22×1.5 (B) |
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 ACQJ80X45-20 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC machining center during part setup, using the external stop to compensate for raw material variance without reprogramming the motion controller.
Packaging Changeover
Adapt sealing head height quickly on a packaging line when switching between different carton sizes, utilizing the 25 to 45 mm extend range to accommodate varied box profiles.
Assembly Press Positioning
Establish trial end positions for pressing bearings on an automated assembly line, allowing operators to tweak the insertion depth mechanically before finalizing the cycle parameters.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-20 the Right Cylinder?
Selecting this 80 mm bore provides substantial power, pushing 2513.2 N and pulling 2267.8 N at 0.5 MPa. If your application requires less force, stepping down to a 63 mm bore drops the push to 1558.6 N, while moving up to a 100 mm bore increases it to 3927.0 N. A fixed-stroke ACQ is sufficient if your end position never varies. When ordering, confirm the 45 mm full stroke, the 20 mm adjustment window, the female M16x2.0 rod-end thread, and the absence of the S magnet option.
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 ACQJ80X45-20 FAQ
This cylinder delivers 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 45 mm, and the external adjuster provides a 20 mm window, creating a usable extend range of 25 to 45 mm.
Adjusting the external stop changes only the extend length, not the piston area, so the output force remains identical to a standard ACQ. Deceleration is provided by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. Note that this model ships without a sensor magnet.
