Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-10B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-10B 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 ACQJ80X75-10B
The ACQJ80X75-10B is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend stroke. You can fine-tune the outward end position on the machine, yielding a usable extend range of 65-75 mm from a 75 mm full stroke, while the retract stroke remains unaffected. Because the piston area is unchanged, output force is identical to a standard ACQ of this bore.
This 80 mm bore unit delivers 2513.2 N of push force at 0.5 MPa and features a male M22x1.5 rod-end thread for direct load coupling. It integrates 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. Operating pressure spans 0.15-1.0 MPa with a PT3/8 port.

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 ACQJ80X75-10B Is Used
Press Fit Depth Tuning
Dialing in exact insertion depths on an automotive bearing press, allowing operators to shorten the extend stroke by up to 10 mm during prototype runs without swapping mechanical spacers.
Carton Flap Folding Stops
Adjusting the end position of a folding mechanism on a packaging line to accommodate varying carton heights, using the external stop to quickly set the 65-75 mm outward travel limit.
Product Changeover Guides
Repositioning a guide rail actuator on a conveyor during product family changeovers, relying on the lock nut to secure the exact extend endpoint for each new package dimension.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-10B the Right Cylinder?
If you need less force, the 63 mm bore provides 1558.6 N push at 0.5 MPa, whereas the 100 mm bore yields 3927.0 N if your application demands higher thrust. A fixed-stroke ACQ is sufficient when the outward position never requires tweaking. To order this adjustable variant correctly, confirm the 80 mm bore, 75 mm full stroke, 10 mm window, the male B rod thread, and note that the S magnet is omitted here.
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 ACQJ80X75-10B 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 full stroke is 75 mm with a 10 mm window, giving a usable extend range of 65-75 mm. The bore is 80 mm, the rod is 25 mm, the port is PT3/8, the male rod-end thread is M22x1.5, and the adjuster thread is M20x1.5.
The external threaded stop with lock nut physically blocks the rod from extending further, shortening the outward stroke only; it does not alter piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration, not adjustable air cushions. Note that a plain cylinder does not hold its load on air loss, so an external rod lock or pilot-operated check valve is required for fail-safe holding.
