Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-10S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 50mm 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 ACQJ80X50-10S
The AirTAC ACQJ80X50-10S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend stroke. You get a usable extend range of 40 to 50 mm, letting you trim the forward end position by up to 10 mm directly on the machine. The return stroke remains fixed at the full 50 mm. An M20x1.5 adjuster thread handles the fine-tuning.
Because the adjuster only restricts travel length and leaves piston area untouched, output force stays identical to a standard ACQ unit of this size. At 0.5 MPa you generate 2513.2 N of push force and 2267.8 N of pull force. This 80 mm bore actuator uses a 25 mm rod, PT3/8 ports, and fixed elastomer bumpers at both ends for end-of-stroke deceleration. The -S option includes a piston magnet compatible with reed or solid-state switches.

| 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 ACQJ80X50-10S Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC lathe during part changeovers without machining new spacer blocks.
Carton Sealing Formers
Alter the flap-folding end point on the fly to accommodate varying box heights on a packaging line.
Assembly Press Tonnage
Set precise pressing depth for bearing insertion operations, allowing quick recipe shifts between product variants.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-10S the Right Cylinder?
If you need slightly less thrust, the 63 mm bore delivers 1558.6 N push at 0.5 MPa, whereas stepping up to the 100 mm bore yields 3927.0 N. A standard fixed-stroke ACQ80 is sufficient if your forward position never requires field adjustment. When ordering this adjustable model, confirm the 80 mm bore, 50 mm full stroke, 10 mm window, -S magnet, and 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 ACQJ80X50-10S FAQ
The usable extend range is 40 to 50 mm (full stroke 50 mm minus the 10 mm window). 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.
No, the external M20x1.5 stop only shortens the extend length; force remains identical to a standard ACQ because piston area is unchanged. Deceleration relies on fixed elastomer bumpers at each end, not adjustable air cushions.
