Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 90mm 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 ACQJ80X90-100B
The ACQJ80X90-100B is a double-acting JIS compact cylinder featuring an external male-threaded piston rod end (M22x1.5) for direct load coupling. An external adjuster screw with an M20x1.5 thread and lock nut restricts the extend end position. With a full stroke of 90mm and a 100mm adjustment window, the usable extend range spans 0 to 90mm, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, force output is identical to a standard ACQ of the same bore. You achieve 2513.2N push and 2267.8N pull at 0.5MPa, scaling to 3518.5N push at 0.7MPa. The unit relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion, and the body retains sensor grooves for reed or solid-state switches, though this specific configuration ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Full stroke | 90 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 ACQJ80X90-100B Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC fixture during part changeovers without machining new stop collars.
Package Diverter Arms
Set precise sorting arm extension distances on packaging lines to handle varying carton widths on the fly.
Press Tonnage Trials
Test material forming depths on a light-duty press by micro-adjusting the extend stop to find the optimal crush distance.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100B the Right Cylinder?
If your application needs less thrust, the 63mm bore offers 1558.6N push at 0.5MPa; if you need more, the 100mm bore provides 3927.0N. A fixed-stroke ACQ is sufficient if your end position never varies. When ordering, verify the 80mm bore, 90mm full stroke, 100mm window, the male B-rod thread (M22x1.5), and note that this unit lacks the S-magnet. Remember that a plain cylinder drifts on air loss, so add an external rod lock 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 ACQJ80X90-100B FAQ
The push force is 2513.2N and pull is 2267.8N at 0.5MPa, with a push of 3518.5N at 0.7MPa and a maximum push of 513kgf at 1.0MPa. The full stroke is 90mm with a 100mm window, yielding a usable extend range of 0-90mm.
An external M20x1.5 threaded stop with a lock nut limits the extend distance without altering piston area, meaning force remains identical to a standard ACQ. The retract stroke is unaffected, and deceleration relies on a fixed NBR elastomer bumper rather than an adjustable air cushion.
