About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-75SB
The AirTAC ACQJ80X70-75SB is a double-acting JIS compact cylinder featuring an external extend stop. A threaded M20x1.5 adjuster with a lock nut lets you fine-tune the extend end position directly on the machine without swapping parts. With a 75mm window, the usable extend range spans 0-70mm. The retract stroke remains completely unaffected.
Because the piston area stays the same, force output is identical to a standard ACQ of this bore. You get 2513.2N push and 2267.8N pull at 0.5MPa. This 80mm bore variant includes a 25mm rod, PT3/8 porting, a male M22x1.5 rod end, and fixed elastomer bumpers. The built-in magnet works with reed or solid-state switches for position sensing.

| 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 ACQJ80X70-75SB Is Used
Press Tooling Setup
Dial in the exact extend position during press tooling setup, allowing operators to compensate for material thickness variations without machining new spacers.
Product Changeover Stops
Adjust the extend end stop on a packaging line to accommodate different carton sizes, enabling rapid product changeover and reducing downtime.
Assembly Machine Trials
Find the optimal end position on an assembly machine by testing different extend lengths, ensuring perfect component seating before final lock-down.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-75SB the Right Cylinder?
Select this 80mm bore if your setup requires a 2513.2N push force at 0.5MPa and on-the-fly extend length tuning. If your application needs less push force, stepping down to a 63mm bore yields 1558.6N. For heavier loads requiring more thrust, moving up to a 100mm bore provides 3927.0N. If the extend position never changes, a fixed-stroke ACQ cylinder suffices. Confirm your ordering essentials: 80mm bore, 70mm full stroke, 75mm window, S magnet, and B male rod 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 ACQJ80X70-75SB FAQ
The usable extend range is 0-70mm (70mm full stroke minus the 75mm window). Force is identical to a standard ACQ: push is 2513.2N and pull is 2267.8N at 0.5MPa, push is 3518.5N at 0.7MPa, and max push is 513kgf at 1.0MPa.
An external M20x1.5 threaded stop with a lock nut limits the extend stroke length without changing piston area, so force remains constant. Fixed elastomer bumpers decelerate the rod near stroke ends. The cylinder does not hold loads on air loss; use an external rod lock for fail-safe holding.
