Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-20B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-20B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 45mm 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 ACQJ80X45-20B
The AirTAC ACQJ80X45-20B is a double-acting JIS compact cylinder with a male-thread piston rod (M22x1.5) that couples directly to your load. An external M20x1.5 threaded stop and lock nut limits the extend end position. You get a usable extend range of 25-45 mm from the 45 mm full stroke, while the retract stroke remains unaffected.
Because the adjustment only shortens travel, the piston area stays the same and force is identical to a standard ACQ of this bore. You get 2513.2 N push and 2267.8 N pull at 0.5 MPa. The unit uses a PT3/8 port, runs at 30-500 mm/s, and relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion.

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ80X45-20B Is Used
Machining Fixture Stops
Dial in the exact extend position on a milling fixture to clamp raw castings securely without machining custom stop spacers.
Assembly Line Changeover
Rapidly shift the extend endpoint within the 25-45 mm range when switching a conveyor line between different product widths.
Carton Sealing Press
Adjust the downward extend stroke on a packaging press to accommodate varying corrugated box heights on the fly.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-20B the Right Cylinder?
If you need less thrust, the 63 mm bore yields 1558.6 N push at 0.5 MPa, whereas the 100 mm bore provides 3927.0 N for heavier loads. Choose this 80 mm bore when your setup demands 2513.2 N of push force alongside precise extend-position tuning. If the extend endpoint never varies, a fixed-stroke ACQ cylinder is sufficient. To order, confirm the 45 mm full stroke, 20 mm adjuster window, PT3/8 porting, and the male M22x1.5 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 ACQJ80X45-20B 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 45 mm with a 20 mm adjuster window, giving a usable extend range of 25-45 mm. The bore is 80 mm, the port is PT3/8, the male rod-end thread is M22x1.5, and the external adjuster thread is M20x1.5.
The external M20x1.5 threaded stop with lock nut mechanically limits how far the rod extends, shortening travel within the 25-45 mm range without changing the piston area, so force remains identical to a standard ACQ. Deceleration comes from a fixed NBR elastomer bumper, not an adjustable air cushion. This plain cylinder does not hold the load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
