Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-75
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-75 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 70mm 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 ACQJ80X70-75
The AirTAC ACQJ80X70-75 is a double-acting JIS compact cylinder featuring an external M20x1.5 threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend stroke anywhere from 0 mm up to the full 70 mm directly on the machine, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, output force equals a standard ACQ of this bore, delivering 2513.2 N push at 0.5 MPa. The body incorporates sensor grooves, though this specific configuration ships without a magnet. Deceleration relies on a fixed NBR elastomer bumper at each end rather than an adjustable air cushion.

| 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 ACQJ80X70-75 Is Used
Machining Fixture Stops
Dial in the exact extend position for varying part sizes on a CNC machining center without machining new stop collars.
Product Changeover Diverter
Rapidly reposition a pneumatic diverter arm on a packaging line during format changes, saving setup time.
Press Trial Positions
Test multiple end-of-stroke pressing depths on an assembly rig before finalizing the mechanical hard stop.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-75 the Right Cylinder?
Selecting this 80 mm bore unit provides a robust 2513.2 N push force at 0.5 MPa, sitting neatly between the 63 mm bore (1558.6 N push) and the 100 mm bore (3927.0 N push). If your application never requires altering the extend end position, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 80 mm bore, 70 mm full stroke, 75 mm adjuster window, female M16x2.0 rod-end thread, and PT3/8 port.
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 ACQJ80X70-75 FAQ
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 usable extend range is 0-70 mm, achieved via the 75 mm adjustment window on the 70 mm full stroke.
The external M20x1.5 threaded stop and lock nut mechanically limit the extend distance without altering the piston area, so force remains identical to a standard ACQ. Retract is unaffected, and end-of-stroke energy is absorbed solely by a fixed NBR elastomer bumper, not an adjustable air cushion.
