Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm bore and 100mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-10SB
The ACQJ140X100-10SB is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 90mm up to the full 100mm stroke directly on your machinery, while the retract stroke remains completely unaffected. This big-bore unit delivers a massive 1570 kgf maximum push at 1.0 MPa.
Because the adjuster only alters stroke length and not piston area, output force stays identical to a standard ACQ of this bore. Equipped with a male M30x1.5 piston rod end for direct load coupling, it also includes an integrated piston magnet (-S) compatible with reed or electronic solid-state switches. Deceleration relies on fixed NBR elastomer bumpers at each end rather than adjustable air cushions.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-10SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø140 mm |
| Full stroke | 100 mm |
| Adjuster thread | M27×2.0 |
| 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 | M22×2.5 (F) / M30×1.5 (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 (Ø140mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 7697 N | 7295 N |
| 0.7 MPa | 10776 N | — |
| Max (@1.0 MPa) | 1570 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 ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-10SB Is Used
Press Tooling Setup
Dial in the exact 90 to 100mm extend position during press tooling changes without machining new spacers or swapping cylinders.
Heavy Assembly Stations
Accommodate varying product heights on heavy assembly lines by turning the external M27x2.0 stopper screw to set the precise end position.
Pallet Positioning
Fine-tune the downward clamping reach on large pallet handling equipment, relying on the 1570 kgf maximum push to secure loads.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-10SB the Right Cylinder?
Selecting this 140mm bore actuator involves sizing against adjacent options: a 125mm bore yields 6135.9N push, whereas a 160mm bore provides 10053.1N push at 0.5 MPa. If your setup never requires end-position adjustments, a fixed-stroke ACQ cylinder will suffice and save complexity. When ordering this adjustable variant, confirm the 100mm full stroke, 10mm window, PT3/8 port size, integrated magnet, and 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 ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-10SB FAQ
This cylinder provides 7696.9N push and 7294.8N pull at 0.5 MPa, 10775.7N push at 0.7 MPa, and a maximum push of 1570 kgf at 1.0 MPa. The 10mm adjustable window allows the extend stroke to be set anywhere between 90mm and 100mm.
The external threaded stop with a lock nut physically limits how far the rod extends, shortening the stroke without changing the force. Fixed NBR bumpers handle end-of-stroke deceleration instead of air cushions. For fail-safe load holding during air loss, you must add an external rod lock or pilot-operated check valve, as the cylinder drifts on its own.
