Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-30S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-30S 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 ACQJ80X90-30S
The AirTAC ACQJ80X90-30S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You get a usable extend range of 60 to 90 mm, letting you fine-tune the forward stroke on the machine without swapping parts. The retract stroke remains unaffected. A piston magnet (-S) is included for position sensing.
Because the adjuster only shortens travel, the piston area stays the same, meaning force is identical to a standard ACQ of this bore. The 80 mm bore delivers 2513.2 N push and 2267.8 N pull at 0.5 MPa. It uses a 25 mm rod, a PT3/8 port, and fixed elastomer bumpers at both ends for end-of-stroke deceleration.

| 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 ACQJ80X90-30S Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC milling fixture. The external stop allows operators to shift the 60-90 mm extend point for different raw casting widths without disassembling the tooling.
Carton Changeover Pushers
Adapt a packaging line diverter rapidly when switching box sizes. The lock nut lets maintenance set a new extended push-off position in seconds, keeping downtime minimal.
Assembly Press Trial
Establish the ideal insertion depth on an automated assembly press. Test various end positions safely within the 30 mm window before locking the nut for full production runs.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-30S the Right Cylinder?
When sizing this unit, consider the 80 mm bore against adjacent options: a 63 mm bore yields 1558.6 N push, while a 100 mm bore provides 3927.0 N at 0.5 MPa. If your application never requires end-position variation, a fixed-stroke ACQ cylinder is simpler and suffices. For this adjustable model, confirm the 90 mm full stroke, the 30 mm window, the -S magnet, and the female M16x2.0 rod-end thread when ordering.
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 ACQJ80X90-30S FAQ
This 80 mm bore cylinder 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 90 mm with a 30 mm adjustable window, providing a usable extend range of 60 to 90 mm.
An external M20x1.5 threaded stop with a lock nut mechanically limits the forward stroke, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration, not an adjustable air cushion. It will not hold a load on air loss; use an external rod lock for fail-safe holding.
