Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 50mm 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 ACQJ80X50-30SB
The AirTAC ACQJ80X50-30SB is a double-acting JIS compact cylinder featuring an external extend stop. A threaded rod-end screw with lock nut lets you fine-tune the forward stroke on the machine without swapping parts. The 30mm adjustment window yields a usable extend range of 20-50mm, while the return stroke remains completely unaffected.
Output force mirrors a standard ACQ because the 80mm piston area is unchanged. The external M20x1.5 adjuster solely limits travel distance. This SB configuration includes a male M22x1.5 piston rod end coupling directly to your load, a piston magnet for position sensing, and fixed NBR elastomer bumpers at both ends.

| Adjuster thread | M20×1.5 |
| 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 ACQJ80X50-30SB Is Used
Machining Changeovers
Dial in the extend stop during product changeovers on milling fixtures to accommodate varying part widths without fabricating new spacers.
Carton Flap Folding
Set precise folding arm endpoints on packaging lines to handle different carton profiles on the fly using the external adjuster nut.
Press Brake Stops
Establish trial end positions for metal forming stops, tweaking the 20-50mm usable extend range until the optimal bend depth is achieved.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30SB the Right Cylinder?
Selecting this 80mm bore yields 2513.2N push at 0.5MPa. Stepping down to a 63mm bore provides 1558.6N push, whereas the larger 100mm bore delivers 3927.0N. If your setup never requires end-position tweaks, a fixed-stroke ACQ cylinder suffices. When ordering, confirm the 50mm full stroke, 30mm window, S magnet, B male rod thread, and PT3/8 port.
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 ACQJ80X50-30SB FAQ
It provides 2513.2N push and 2267.8N pull at 0.5MPa, 3518.5N push at 0.7MPa, and a maximum push of 513kgf at 1.0MPa. The full stroke is 50mm with a 30mm window, giving a usable extend range of 20-50mm.
The external M20x1.5 threaded stop limits only the extend distance; force is identical to a standard ACQ. Fixed NBR bumpers decelerate the rod near stroke ends but do not hold the load on air loss, so an external rod lock is needed for fail-safe holding.
