Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-50SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-50SB 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 ACQJ80X45-50SB
The AirTAC ACQJ80X45-50SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut to fine-tune the extend end position. With a full stroke of 45mm and a 50mm adjustment window, you can set the usable extend range from 0mm up to 45mm directly on your machinery. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, output force stays identical to a standard ACQ of this bore, delivering 2513.2N push and 2267.8N pull at 0.5MPa. The 80mm bore uses a PT3/8 port and a 25mm rod. This model includes a male M22x1.5 rod-end thread for direct load coupling, a built-in magnet for electronic or reed switches, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.

| 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 |

| 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 ACQJ80X45-50SB Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC machining center during part changeovers without swapping out cylinder hardware.
Carton Forming Arms
Adjust the push depth on packaging lines to accommodate varying box sizes, ensuring precise flap folding without retooling.
Press Pin Depth Setting
Fine-tune pin insertion depth on an assembly press to test different material thicknesses or trial end positions safely.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-50SB the Right Cylinder?
If you need slightly less thrust, the 63mm bore yields 1558.6N push at 0.5MPa, whereas stepping up to the 100mm bore provides 3927.0N push. Choose this 80mm unit when your application demands up to 513kgf maximum push alongside variable extend positioning. If the extend distance never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, verify the 45mm full stroke, 50mm window, S magnet, and 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 ACQJ80X45-50SB FAQ
It provides 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 50mm window, allowing a usable extend range of 0-45mm.
An external M20x1.5 threaded stop with a lock nut limits the extend length without changing the piston area, so force remains identical to a standard ACQ. Deceleration relies on fixed elastomer bumpers, and the built-in -S magnet works with reed or solid-state switches.
