Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-30S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-30S 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 ACQJ140X100-30S
The AirTAC ACQJ140X100-30S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut to precisely limit the extend end position. With a full stroke of 100 mm and a 30 mm adjustment window, you can tune the usable extend range from 70 mm up to 100 mm directly on the machine. The retract stroke remains completely unaffected by this mechanism. As a big-bore compact variant, it handles strokes up to 300 mm within a space-saving riveted body.
Because the adjuster only restricts travel length and not the piston area, the output force is identical to a standard ACQ of the same bore. At 0.5 MPa, it delivers 7696.9 N of push force and 7294.8 N of pull force. The unit incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion, and the included -S magnet allows tracking with either reed or solid-state electronic switches.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-30S Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-30S |
|---|---|
| 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 ACQJ140X100-30S Is Used
Press Tonnage Setup
Dial in the exact 70-100 mm extend position during press tooling changeovers, ensuring varied product batches receive the correct forming depth without machining new spacers.
Heavy Material Stops
Regulate the extend stop on large metal-stamping lines to accommodate different sheet widths, relying on the 7696.9 N push force to hold heavy workpieces securely.
Robotic Hand Calibration
Fine-tune the gripping reach of large pneumatic robotic hands during initial run-in, testing multiple end positions rapidly via the M27x2.0 external adjuster before locking the nut.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-30S the Right Cylinder?
If your application requires slightly less thrust, the 100 mm bore variant provides 3927.0 N push at 0.5 MPa, whereas stepping up to the 160 mm bore yields 10053.1 N push. For this 140 mm bore, the piston rod is 32 mm thick, the standard port is PT3/8, and the external adjuster utilizes an M27x2.0 thread. Choose this adjustable model over a fixed-stroke ACQ only when production setups demand frequent end-position tweaking without swapping hardware. Confirm your ordering essentials: 140 mm bore, 100 mm full stroke, 30 mm window, -S magnet, and the default female M22x2.5 rod-end 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 ACQJ140X100-30S FAQ
The usable extend range is 70-100 mm (a 100 mm full stroke minus up to a 30 mm window). Force is identical to a standard ACQ: 7696.9 N push and 7294.8 N pull at 0.5 MPa, 10775.7 N push at 0.7 MPa, and a maximum push of 1570 kgf at 1.0 MPa.
An external threaded stop and lock nut limit the extend travel, allowing on-machine tuning without altering the retract stroke. Deceleration is handled by fixed NBR elastomer bumpers, not adjustable air cushions. Note that a plain compact cylinder will not hold its load on air loss; use an external rod lock for fail-safe holding.
