Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-30SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 40mm 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 ACQJ80X40-30SB
The AirTAC ACQJ80X40-30SB is a double-acting JIS compact cylinder with an external extend stop. A threaded adjuster with a lock nut lets you set the extend end position from 10 to 40 mm on the machine, while the 40 mm retract stroke remains unaffected. The piston area is unchanged, so force equals a standard ACQ of this bore: 2513.2 N push and 2267.8 N pull at 0.5 MPa.
This 80 mm bore unit uses a PT3/8 port and a 25 mm rod. The -S option provides a piston magnet compatible with reed or solid-state switches, and the -B option gives a male M22x1.5 rod-end thread for direct load coupling. Fixed NBR elastomer bumpers absorb impact at both ends, operating reliably from -20 to +70 C at 0.15-1.0 MPa.

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 ACQJ80X40-30SB Is Used
Machining Fixture Stops
Dial in the extend stop from 10 to 40 mm during part setup to accommodate varying workpiece thicknesses without swapping mechanical spacers.
Assembly Line Changeover
Quickly reposition the extend end position on automated presses when switching between different product variants on the same line.
Carton Forming Machines
Fine-tune the folding arm extension to handle different carton depths during production trials without re-engineering the motion sequence.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-30SB the Right Cylinder?
If your application needs less push force, the 63 mm bore offers 1558.6 N push at 0.5 MPa; for higher force, the 100 mm bore yields 3927.0 N. Choose this 80 mm model when you need 2513.2 N push alongside on-machine extend tuning. If the end position never varies, a fixed-stroke ACQ suffices. To order, confirm the 80 mm bore, 40 mm full stroke, 30 mm window, -S magnet, and -B male M22x1.5 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 ACQJ80X40-30SB 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 40 mm with a 30 mm window, giving a usable extend range of 10-40 mm; the retract stroke is unaffected.
An M20x1.5 threaded stop with a lock nut limits the extend stroke, changing only the travel length, not the piston area, so force is identical to a standard ACQ. Fixed NBR bumpers decelerate the load near stroke ends, but the cylinder will not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
