Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-40B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-40B 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 ACQJ80X45-40B
The AirTAC ACQJ80X45-40B is a double-acting JIS compact cylinder with a male-thread (M22x1.5) piston rod end that couples directly to your load. A PT3/8 port and 25mm rod handle heavy-duty actuation. The external M20x1.5 threaded stop and lock nut let you limit the extend stroke on the machine, providing a usable extend range of 5-45mm. The retract stroke remains completely unaffected.
Because the piston area stays constant, the force output is identical to a standard ACQ of this bore, delivering 2513.2N push and 2267.8N pull at 0.5MPa. The unit relies on a fixed NBR elastomer bumper at each end for end-of-travel deceleration rather than an adjustable air cushion. Operating speed spans 30-500mm/s across a 0.15-1.0MPa pressure range.

| 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 ACQJ80X45-40B Is Used
Machining Fixture Stops
Dial in the exact 5-45mm extend position during CNC setup to accommodate varying raw casting lengths without machining custom spacers.
Assembly Line Changeover
Rapidly adjust the extend endpoint on an automated press when switching between different product variants on the same conveyor.
Carton Forming Trials
Test and fine-tune the end stop position on a packaging machine to ensure perfect flap folding depth before locking the nut.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-40B the Right Cylinder?
If you require less force, the 63mm bore yields 1558.6N push at 0.5MPa, whereas the 100mm bore provides 3927.0N push. This 80mm bore hits 2513.2N push and 2267.8N pull at 0.5MPa, peaking at 513kgf max push at 1.0MPa. A fixed-stroke ACQ cylinder is sufficient if your end position never varies. When ordering, verify the 45mm full stroke, 40mm window, male rod thread, and PT porting. Note that this unit ships without a magnet (-S) for reed or solid-state switches.
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 ACQJ80X45-40B 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, and the external stop allows an adjustable extend range of 5-45mm.
The external M20x1.5 threaded stop with a lock nut limits only the extend stroke length, so the force remains identical to a standard ACQ. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion.
