Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-10SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-10SB 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 ACQJ80X50-10SB
The AirTAC ACQJ80X50-10SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. With a 50 mm full stroke and a 10 mm adjustment window, the usable extend range spans 40 to 50 mm. The retract stroke remains completely unaffected by this mechanism. An M20x1.5 adjuster thread enables precise on-machine end-position tuning without swapping components.
Because the piston area is unchanged, the force output is identical to a standard ACQ of this bore, delivering 2513.2 N push at 0.5 MPa. This bore 80 unit features a 25 mm rod, PT3/8 port, and fixed elastomer bumpers at both ends for end-of-stroke deceleration. The -S magnet allows tracking by reed or solid-state switches, while the -B option provides an M22x1.5 male rod-end thread for direct load coupling.

| 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 ACQJ80X50-10SB Is Used
Machining Fixture Stops
Dial in the exact extend position of a 25 mm rod during a product changeover on a milling line, using the lock nut to set the stop between 40 and 50 mm.
Carton Sealing Flights
Alter the extend endpoint on a packaging conveyor to accommodate varying box sizes without replacing the cylinder or mounting hardware.
Press Trial Positions
Test different extend end positions on an assembly press to find the optimal contact point before locking the M20x1.5 external adjuster down.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-10SB the Right Cylinder?
For lower force requirements, the bore 63 version provides 1558.6 N push at 0.5 MPa, whereas stepping up to the bore 100 model yields 3927.0 N push. If your application requires a fixed 50 mm extend and no on-the-fly adjustments, a standard ACQ80X50 cylinder is sufficient. When ordering this adjustable variant, confirm the 80 mm bore, 50 mm full stroke, 10 mm 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 ACQJ80X50-10SB FAQ
The usable extend range is 40-50 mm (50 mm full stroke minus the 10 mm window). Force is identical to 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 external M20x1.5 threaded stop with lock nut limits only the extend stroke length; force remains unchanged. Deceleration relies on fixed elastomer bumpers, not adjustable air cushions. A plain cylinder will not hold a load on air loss, so use an external rod lock for fail-safe holding.
