Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X35-40SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X35-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 35mm 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 ACQJ80X35-40SB
The AirTAC ACQJ80X35-40SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the EXTEND end position. You can fine-tune the usable extend range from 0 up to 35 mm on the machine without swapping parts, while the RETRACT stroke remains completely unaffected. It includes a male-thread piston rod end (M22x1.5) that couples directly to your load.
Because the adjuster only alters stroke length and not piston area, the output force is IDENTICAL to a standard ACQ of this 80 mm bore. It generates 2513.2 N of push and 2267.8 N of pull at 0.5 MPa. The unit relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration, and the built-in piston magnet (-S) works with reed or electronic solid-state switches.

| 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 ACQJ80X35-40SB Is Used
Machining Fixture Stops
Dial in the exact extend position during product-changeover on a CNC machining center, using the external M20x1.5 stopper to accommodate varying raw part lengths.
Carton Sealing Tampers
Adjust the extend stroke on a packaging line to match different box heights, ensuring the male M22x1.5 rod end contacts the flap precisely without crushing the container.
Assembly Press Positioning
Set trial end positions for pressing bearings on an automated assembly line, tweaking the 0-35 mm usable range on the fly until the optimal insertion depth is found.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X35-40SB the Right Cylinder?
If you need slightly less thrust, the 63 mm bore yields 1558.6 N push at 0.5 MPa, whereas stepping up to a 100 mm bore provides 3927.0 N. A fixed-stroke ACQ is sufficient if your extend position never requires adjustment. To order this version correctly, confirm the 80 mm bore, 35 mm full stroke, 40 mm adjuster window, -S magnet, and -B male rod thread. Note that a plain ACQ-type does not hold its load on air loss; add an external rod lock or pilot-operated check valve for a fail-safe hold.
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 ACQJ80X35-40SB 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 35 mm with a 40 mm adjustable window, yielding a usable extend range of 0-35 mm.
The external threaded stop with lock nut limits the extend length only, so the force is IDENTICAL to a standard ACQ of this bore because the piston area is unchanged. The cylinder uses a fixed NBR elastomer bumper at each end for deceleration, and the -S magnet supports reed or electronic solid-state switches.
