Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-40B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-40B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 40mm 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 ACQJ80X40-40B
The AirTAC ACQJ80X40-40B is a double-acting JIS compact cylinder featuring a male-threaded piston rod (M22x1.5) and an external M20x1.5 threaded stop with a lock nut. This mechanism lets you limit the extend end position on the machine, providing a usable extend range of 0-40mm from the 40mm full stroke. The retract distance remains completely unaffected.
Because the adjuster only restricts travel and not the piston area, force output is identical to a standard ACQ of the same bore. At 0.5 MPa it delivers 2513.2N of push and 2267.8N of pull. The body incorporates fixed NBR elastomer bumpers at each end for end-of-stroke deceleration, and includes sensor grooves, though this specific configuration ships without a magnet.

| Bore size | Ø80 mm |
| Full stroke | 40 mm |
| 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 ACQJ80X40-40B Is Used
Machining Fixture Stops
Dial in the exact extend position for varying part dimensions on a CNC machining fixture without swapping out physical stop blocks.
Carton Changeover
Quickly alter the extend stroke limit during packaging line product changeovers to accommodate different carton sizes.
Press Trial Positions
Test different end positions on a light assembly press to find the optimal contact depth before finalizing the mechanical setup.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-40B the Right Cylinder?
For a 0.5 MPa push requirement around 2513N, the 80mm bore is appropriate; dropping to a 63mm bore yields 1558.6N, while a 100mm bore provides 3927N. If your extend end position never varies, a fixed-stroke ACQ cylinder is sufficient, but this adjustable model excels in setups requiring frequent end-position tuning. When ordering, verify the 40mm full stroke, the 40mm adjustment window, the male rod thread, and the PT3/8 port. Note that a plain cylinder will not hold its load on air loss; add an external rod lock or pilot-operated check valve for fail-safe holding.
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 ACQJ80X40-40B FAQ
It delivers 2513.2N push and 2267.8N pull at 0.5 MPa, 3518.5N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. The full stroke is 40mm with a 40mm adjustment window, giving a usable extend range of 0-40mm. The piston rod is 25mm with a male M22x1.5 thread, the adjuster thread is M20x1.5, and the port is PT3/8.
The external threaded stop with a lock nut physically limits how far the rod extends, shortening the extend stroke without changing the piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected. Deceleration is handled by fixed NBR elastomer bumpers at each end, not an adjustable air cushion, so for high-speed or high-energy loads you should add an external shock absorber or slow the approach.
