Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-20SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-20SB 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 ACQJ80X45-20SB
The AirTAC ACQJ80X45-20SB is a double-acting JIS compact cylinder with a 45mm full stroke and a 20mm external adjustment window. An external M20x1.5 threaded stop and lock nut restricts the extend travel, yielding a usable forward range of 25 to 45mm. The retract movement remains completely unaffected by this mechanism. Because the piston dimensions are unchanged, the output force is identical to a standard ACQ of the same bore.
This unit features a 25mm male-threaded piston rod (M22x1.5) for direct load coupling, a PT3/8 port, and a built-in piston magnet for electronic or reed sensing. It relies on a fixed NBR elastomer bumper at each end for end-of-travel deceleration rather than adjustable pneumatic cushions. The compact C-clip body design saves machine space without sacrificing strength.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Full stroke | 45 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ80X45-20SB Is Used
CNC Fixture Positioning
Dial in the exact clamping reach on CNC machining centers during part family changeovers without machining new spacer blocks.
Carton Sealing Stops
Vary the flap folding arm endpoint on packaging lines to accommodate different carton heights rapidly on the fly.
Press Trial Endpoints
Test multiple pressing depths on assembly presses safely by limiting the forward stroke within the 25-45mm window.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-20SB the Right Cylinder?
Select this 80mm bore when your setup demands 2513.2N push force at 0.5MPa or up to 513kgf maximum push at 1.0MPa. If your application needs less thrust, the 63mm bore yields 1558.6N push at 0.5MPa, whereas stepping up to the 100mm bore provides 3927.0N push at 0.5MPa. A fixed-stroke ACQ suffices if the extend endpoint never varies. To order, confirm the 80mm bore, 45mm full stroke, 20mm window, the S magnet option, and the 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 ACQJ80X45-20SB FAQ
It delivers 2513.2N push and 2267.8N pull at 0.5MPa, 3518.5N push at 0.7MPa, and a maximum push of 513kgf at 1.0MPa. The full stroke is 45mm with a 20mm window, allowing an adjustable extend range of 25-45mm.
The external M20x1.5 threaded stop with lock nut limits only the extend length, leaving retract unaffected and keeping force identical to a standard ACQ. Fixed NBR elastomer bumpers absorb impact at both ends, and the built-in magnet works with reed or solid-state switches.
