Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 80mm 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 ACQJ80X80-30SB
The AirTAC ACQJ80X80-30SB is a double-acting JIS compact cylinder featuring an external extend stop. A threaded screw with a lock nut restricts how far the rod travels outward, allowing you to set the usable extend range from 50 mm up to the full 80 mm. The retract distance remains fixed at 80 mm. Because the piston area stays constant, output force matches a standard ACQ exactly.
Equipped with a male M22x1.5 piston rod end, this unit couples directly to your load. It includes a built-in magnet (-S) for positioning sensors and a 25 mm rod. The body uses a PT3/8 port and relies on fixed NBR elastomer bumpers at both ends rather than adjustable pneumatic cushions.

| 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 ACQJ80X80-30SB Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC mill fixture without machining new spacers, adjusting the outward stroke from 50 to 80 mm as raw part dimensions vary.
Carton Changeover Pusher
Accommodate different box widths on a packaging line by tweaking the external stop nut, ensuring precise product transfer without swapping the actuator.
Assembly Press Positioning
Establish trial end positions for pressing bearings on an assembly line, fine-tuning the extend limit to prevent over-travel while maintaining full 513 kgf peak capacity.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30SB the Right Cylinder?
Choosing this 80 mm bore yields a push force of 2513.2 N and a pull force of 2267.8 N at 0.5 MPa. If your application requires less thrust, stepping down to a 63 mm bore provides 1558.6 N of push, whereas moving up to a 100 mm bore offers 3927.0 N. Select this adjustable version only if your setup requires on-the-fly extend length tuning; otherwise, a fixed-stroke ACQ cylinder is sufficient. Confirm your requirements for the 80 mm full stroke, the 30 mm adjustment window, the magnet option, and the male rod thread before ordering.
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 ACQJ80X80-30SB FAQ
At 0.5 MPa it provides 2513.2 N push and 2267.8 N pull force, and 3518.5 N push at 0.7 MPa. The maximum push is 513 kgf at 1.0 MPa. The full stroke is 80 mm, and with the 30 mm adjustment window, the usable extend range is 50-80 mm.
An M20x1.5 threaded screw with a lock nut limits the outward travel, changing only the stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers, not an air cushion. It will not hold a load on air loss, so an external rod lock is needed for fail-safe holding.
