Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-40SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 45mm 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 ACQJ80X45-40SB
The AirTAC ACQJ80X45-40SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. With a 40mm adjustment window, the usable extend range runs from 5mm up to the full 45mm stroke, while the retract stroke remains completely unaffected. This allows on-machine end-position tuning without swapping parts.
Because the piston area is unchanged, the force output is identical to a standard ACQ of the same bore, delivering 2513.2N push and 2267.8N pull at 0.5MPa. The cylinder includes a male M22x1.5 piston rod end for direct load coupling, a PT3/8 port, and a fixed NBR elastomer bumper at each end. The -S magnet enables position sensing via reed or solid-state switches.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Full stroke | 45 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ80X45-40SB Is Used
Machining Fixture Tuning
Dial in the exact clamping reach on a CNC fixture by adjusting the extend stop from 5 to 45mm, accommodating different part heights without fabricating custom spacers.
Packaging Changeover Stops
Modify the pressing or sealing height during product format changeovers on a packaging line, using the external M20x1.5 adjuster to hit new end positions rapidly.
Assembly Press Trials
Establish the precise insertion depth for a press-fit station by testing various extend positions on the fly, relying on the fixed elastomer bumper for consistent end deceleration.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-40SB the Right Cylinder?
For 0.5MPa operations, this 80mm bore yields 2513.2N push force; sizing down to a 63mm bore provides 1558.6N, whereas sizing up to a 100mm bore offers 3927.0N. If your setup never requires altering the extend end position, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable variant, confirm the 80mm bore, 45mm full stroke, 40mm 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 ACQJ80X45-40SB FAQ
The cylinder provides 2513.2N push and 2267.8N pull force at 0.5MPa, 3518.5N push at 0.7MPa, and a maximum push of 513kgf at 1.0MPa. The full stroke is 45mm, featuring a 40mm adjustment window that permits a usable extend range of 5-45mm.
No, the external M20x1.5 threaded stop only limits the extend stroke length; the piston area remains the same, so force is identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for end deceleration and will not hold a load on air loss, requiring an external rod lock for fail-safe holding.
