Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-50S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-50S 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 ACQJ80X75-50S
The AirTAC ACQJ80X75-50S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that restricts the extend end position. You can fine-tune the extend stroke on the machine across a usable range of 25 to 75 mm, while the retract stroke remains completely unaffected. The piston rod diameter is 25 mm, and the female rod-end thread is M16x2.0.
Because the adjuster only limits travel and not the piston area, the output force stays identical to a standard ACQ of the same bore. At 0.5 MPa you get 2513.2 N of push force and 2267.8 N of pull force. The unit relies on a fixed elastomer bumper at each end for deceleration and includes a built-in magnet for position sensing.

| Bore size | Ø80 mm |
| Full stroke | 75 mm |
| Adjuster thread | M20×1.5 |
| Port size | PT3/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| 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 ACQJ80X75-50S Is Used
Machining Center Clamping
Dial in the exact clamping reach on a CNC fixture during setup, absorbing part length variations without machining new stop collars.
Packaging Line Diverters
Shift the extend endpoint by up to 50 mm to handle different carton sizes on a packaging line during rapid product changeover.
Press Ejection Stroke Tuning
Set a precise ejection distance on an assembly press to safely clear varying workpiece heights before triggering the retract stroke.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-50S the Right Cylinder?
When sizing this bore 80 unit, stepping down to a 63 mm cylinder lowers the 0.5 MPa push force to 1558.6 N, whereas stepping up to a 100 mm bore raises it to 3927.0 N. If your application never requires altering the end position, a fixed-stroke ACQ cylinder will suffice. For this adjustable model, confirm the 75 mm full stroke, the 50 mm window, the S magnet option, and the female M16x2.0 rod thread when ordering.
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 ACQJ80X75-50S FAQ
The usable extend range is 25 to 75 mm. It 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 M20x1.5 threaded stop with lock nut limits the extend stroke length only, meaning force is unchanged from a standard ACQ. Deceleration relies on a fixed elastomer bumper, and the built-in magnet works with reed or electronic solid-state switches.
