Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-20B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-20B 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 ACQJ80X75-20B
The AirTAC ACQJ80X75-20B is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut on the rod-end side. This mechanism lets you fine-tune the extend end position on the machine without swapping parts, yielding a usable extend range of 55-75 mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, output force is identical to a standard ACQ of the same bore: 2513.2 N push and 2267.8 N pull at 0.5 MPa. This specific variant includes a male M22x1.5 rod-end thread for direct load coupling and ships without a magnet, though the body retains sensor grooves. It uses a fixed NBR elastomer bumper at each end for end-of-stroke deceleration.

| Port size | PT3/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ80X75-20B Is Used
Machining Fixture Stops
Dial in the exact extend position for varying raw material blanks on a milling fixture without machining new stop spacers.
Carton Changeover Flaps
Quickly reposition the extend end stop during product format changeovers on a packaging line to accommodate different box heights.
Press Trial Positions
Establish precise trial end positions for a light assembly press, testing different engagement depths before finalizing the mechanical setup.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-20B the Right Cylinder?
When sizing this 80 mm bore actuator, note the adjacent options: dropping to a 63 mm bore yields 1558.6 N push, while stepping up to a 100 mm bore provides 3927.0 N push at 0.5 MPa. If your extend position never varies, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable version correctly, confirm the 80 mm bore, 75 mm full stroke, 20 mm window, the male B rod thread, and PT3/8 porting.
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 ACQJ80X75-20B FAQ
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 full stroke is 75 mm with a 20 mm window, allowing an adjustable extend range of 55-75 mm. The retract stroke is unaffected.
The external M20x1.5 threaded stop with lock nut limits the extend stroke length only; it does not change the piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at each end, not adjustable air cushions. Note that this model ships without a sensor magnet, though reed or solid-state switches can still be mounted in the body grooves.
