Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X30-30SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X30-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 30mm 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 ACQJ80X30-30SB
The AirTAC ACQJ80X30-30SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the EXTEND end position. The usable extend range is 0-30 mm (the 30 mm full stroke minus the 30 mm adjustment window), while the RETRACT stroke remains unaffected. An M20x1.5 adjuster screw lets you fine-tune the endpoint on the machine without swapping parts.
Because the piston area is unchanged, the force is IDENTICAL to a standard ACQ of this 80 mm bore: 2513.2 N push and 2267.8 N pull at 0.5 MPa. The cylinder body uses fixed NBR elastomer bumpers at each end for end-of-stroke deceleration, and the -S magnet enables position detection with reed or solid-state switches.

| Bore size | Ø80 mm |
| Full stroke | 30 mm |
| 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 |

| Speed range | 30 – 500 mm/s |
| 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 ACQJ80X30-30SB Is Used
Product Changeover Stops
Dial in the extend position on a machining fixture when switching between part families, using the external stop to set the exact 0-30 mm reach without reprogramming motion controls.
Variable Format Flap Folding
Adjust the extend stroke on the fly for different carton widths on a packaging line, ensuring the rod end meets the material precisely without over-travel.
Trial End Positions
Test and verify the exact extend endpoint during machine setup, locking the M20x1.5 adjuster nut in place once the optimal contact position is found.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X30-30SB the Right Cylinder?
At 0.5 MPa this 80 mm bore delivers 2513.2 N push force; sizing down to a 63 mm bore yields 1558.6 N push, while stepping up to a 100 mm bore provides 3927.0 N. If your extend endpoint never varies, a fixed-stroke ACQ cylinder is simpler and sufficient. When ordering, confirm the 80 mm bore, 30 mm full stroke, 30 mm adjustment window, the -S magnet, and the -B male M22x1.5 rod end.
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 ACQJ80X30-30SB FAQ
The usable extend range is 0-30 mm (30 mm full stroke minus the 30 mm window). The force equals a standard ACQ: 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 port is PT3/8 and the rod is 25 mm.
An external M20x1.5 threaded stop with a lock nut limits the extend stroke only; the retract stroke is unaffected, and the force is identical to a standard ACQ because the piston area is unchanged. The cylinder uses fixed NBR elastomer bumpers, not an adjustable air cushion. A plain ACQ does not hold its load on air loss, so use an external rod lock for fail-safe holding.
