Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-20S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-20S 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 ACQJ80X50-20S
The AirTAC ACQJ80X50-20S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut. This mechanism restricts the extend stroke, providing a usable forward range of 30 to 50 mm from the 50 mm full stroke. The retract distance remains completely unaffected.
Because the piston area is unchanged, the output force equals a standard ACQ of this bore, yielding 2513.2 N push and 2267.8 N pull at 0.5 MPa. The unit incorporates fixed NBR elastomer bumpers at both ends for end-of-travel deceleration. Equipped with a -S magnet, the body grooves accept reed or electronic solid-state switches for position sensing.

| 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 ACQJ80X50-20S Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC milling fixture during part changeovers, adjusting the 30 to 50 mm forward travel without swapping hardware.
Carton Sealing Tippers
Set precise flap folding positions on a packaging line by tweaking the external stop nut to accommodate varying box dimensions on the fly.
Press Assembly Probes
Establish trial end positions for a pressing operation, safely limiting the 2513.2 N extend force before finalizing a hard mechanical stop.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-20S the Right Cylinder?
For 0.5 MPa push requirements around 2513.2 N, this 80 mm bore is a solid choice; dropping to a 63 mm bore reduces push to 1558.6 N, while stepping up to 100 mm increases it to 3927.0 N. If your application always uses a fixed 50 mm extend and never requires on-the-fly shortening, a standard ACQ80X50 cylinder is sufficient. When ordering, confirm the 80 mm bore, 50 mm full stroke, 20 mm adjuster window, -S magnet, and the default female M16x2.0 rod end 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 ACQJ80X50-20S FAQ
The usable extend range is 30 to 50 mm (a 20 mm window off the 50 mm full stroke). Force is identical to a standard ACQ: push is 2513.2 N and pull is 2267.8 N at 0.5 MPa, push is 3518.5 N at 0.7 MPa, and maximum push is 513 kgf at 1.0 MPa.
An external M20x1.5 threaded stop with a lock nut limits the forward travel; force is unchanged because the piston area stays the same. The cylinder uses fixed elastomer bumpers for deceleration, not adjustable air cushions. It will not hold a load on air loss, so an external rod lock or pilot-operated check valve is required for fail-safe holding.
