Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-10S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 70mm 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 ACQJ80X70-10S
The AirTAC ACQJ80X70-10S 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 stroke anywhere from 60 mm up to the full 70 mm directly on your equipment, while the retract stroke remains completely unaffected. Because the piston area stays the same, output force is identical to a standard ACQ of this bore.
This 80 mm bore unit features a 25 mm piston rod, PT3/8 porting, and an M20x1.5 adjuster thread. It includes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. Equipped with an -S piston magnet, the body grooves accept both reed and solid-state electronic sensors for position detection.

| 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 ACQJ80X70-10S Is Used
Machining Fixture Clamping
Dial in the exact clamping reach on a CNC lathe during product-changeover, shortening the extend stroke from 70 mm down to 60 mm without machining new spacer blocks.
Carton Sealing Formers
Adjust the folding arm end stop on the fly for different carton depths, ensuring precise flap alignment while the cylinder maintains its full 2513.2 N push force.
Press Brake Backgauge
Set trial end positions for metal bending operations, allowing operators to tweak the 60 to 70 mm extend window to dial in complex sheet metal angles.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-10S the Right Cylinder?
Selecting this 80 mm bore provides a push force of 2513.2 N and a pull force of 2267.8 N at 0.5 MPa. If your application requires less force, stepping down to a 63 mm bore yields 1558.6 N of push, while moving up to a 100 mm bore provides 3927.0 N. A fixed-stroke ACQ is sufficient if your end position never varies, but this adjustable model is ideal when you need trial end positions or product-changeover stops. Confirm your ordering essentials: 80 mm bore, 70 mm full stroke, 10 mm window, S magnet, and 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 ACQJ80X70-10S FAQ
The usable extend range is 60-70 mm (70 mm full stroke minus a 10 mm adjustable window). 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.
The external M20x1.5 threaded stop with lock nut limits only the extend length, leaving retract unchanged and not altering piston area or force. The cylinder uses fixed NBR elastomer bumpers for deceleration rather than adjustable air cushions, and the included -S magnet works with both reed and electronic solid-state switches.
