Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-30
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-30 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 ACQJ80X75-30
The AirTAC ACQJ80X75-30 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You get a usable extend range of 45-75 mm (the 75 mm full stroke minus the 30 mm window), while the retract stroke remains completely unaffected. Because the piston area is unchanged, the force output is identical to a standard ACQ of this bore.
This 80 mm bore unit delivers 2513.2 N of push force and 2267.8 N of pull force at 0.5 MPa, peaking at a 513 kgf maximum push at 1.0 MPa. It incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and includes sensor grooves, though this specific configuration ships without a magnet. The PT3/8 port and 25 mm rod ensure robust pneumatic performance.

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 ACQJ80X75-30 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC machining fixture during part family changeovers without machining new stop collars.
Diverter Arm Positioning
Set the perfect extend distance for a conveyor sorting arm to accommodate varying package widths on the fly.
Press Stroke Setup
Establish trial end positions on a light assembly press, tweaking the 45-75 mm range to prevent overtravel and material damage.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-30 the Right Cylinder?
For lower force requirements, the 63 mm bore provides 1558.6 N of push at 0.5 MPa, while stepping up to the 100 mm bore yields 3927.0 N. If your machine design has a fixed, unchanging extend position and never requires on-the-fly adjustments, a standard ACQ80 cylinder will suffice. When ordering, verify the 80 mm bore, 75 mm full stroke, 30 mm adjustable window, female M16x2.0 rod thread, and whether you need the -S magnet option for reed or solid-state switches.
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 ACQJ80X75-30 FAQ
The usable extend range is 45-75 mm (75 mm full stroke minus the 30 mm window). Force is identical to a standard ACQ80: 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.
An M20x1.5 threaded adjuster with a lock nut mechanically limits the extend stroke, meaning the rod drifts and will not hold the load on air loss. The cylinder relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion, so external shock absorbers are recommended for high-energy loads.
