About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-40SB
The AirTAC ACQJ80X80-40SB is a double-acting JIS compact cylinder featuring an external extend-stop mechanism. By turning the M20x1.5 adjuster screw and locking the nut, you can fine-tune the forward end position on the machine, yielding a usable extend range of 40 to 80 mm. The return stroke remains fixed at its standard length.
Because the adjustment merely limits forward travel without altering piston dimensions, output force stays identical to a standard ACQ of this bore. You get 2513.2 N push and 2267.8 N pull at 0.5 MPa, alongside a robust Ø25 mm rod with an M22x1.5 male thread for direct mounting. NBR elastomer bumpers absorb impact at both ends, and the built-in magnet (-S) supports reed or solid-state sensing.

| 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 ACQJ80X80-40SB Is Used
Machining Fixture Stops
Dial in the exact clamping reach on CNC milling fixtures without machining custom spacers, accommodating multiple part lengths on the same tombstone.
Carton Forming Tolerance
Compensate for varying corrugated board thicknesses during case erecting by tweaking the extend endpoint on the fly to prevent crushing.
Press Brake Backgauges
Establish trial end positions for sheet metal bending operations, allowing operators to micro-adjust the stop depth safely before final production runs.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-40SB the Right Cylinder?
Selecting this bore is ideal when your application requires substantial thrust—up to 513 kgf maximum at 1.0 MPa—combined with variable positioning. If your process demands less push, dropping down to a 63 mm bore yields 1558.6 N at 0.5 MPa, whereas stepping up to 100 mm provides 3927.0 N. Choose this adjustable model if setup dimensions vary; otherwise, a fixed-stroke ACQ is simpler. Confirm the 80 mm full stroke, 40 mm window, male rod thread (-B), and magnet (-S) when 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 ACQJ80X80-40SB FAQ
It delivers 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 80 mm with a 40 mm adjustment window, allowing a usable extend range of 40 to 80 mm.
The M20x1.5 threaded stop with lock nut physically limits how far the rod extends, shortening the forward stroke without changing piston area or force. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. Note that a standard cylinder will drift if air pressure is lost, so use an external rod lock for fail-safe load holding.
