Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-50S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm bore and 200mm 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 ACQJ140X200-50S
The AirTAC ACQJ140X200-50S is a big-bore JIS compact cylinder featuring a double-acting single rod and an external stroke adjuster. A threaded stop with a lock nut restricts the extend end position, giving a usable forward range of 150-200mm from the 200mm full stroke. The retract distance remains completely unaffected by this mechanism.
Because the adjustment only limits travel length and not piston area, output matches a standard ACQ exactly. You get 7696.9N push and 7294.8N pull at 0.5MPa. The Ø32mm rod uses an M27x2.0 adjuster thread, and NBR elastomer bumpers handle end-stop deceleration across the 30-500mm/s speed range.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-50S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø140 mm |
| Full stroke | 200 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 ACQJ140X200-50S Is Used
Heavy Press Forming
Dial in the exact material deflection on a 200-ton press by tuning the 150-200mm extend stop, ensuring consistent panel forming without replacing hard stops.
Automotive Component Clamping
Adapt clamp end positions rapidly during vehicle model changeovers on an assembly line, using the external M27x2.0 adjuster to set precise gripping depth.
Large Fixture Positioning
Probe trial end positions for heavy machining fixtures, securely locking the rod nut once the optimal 150-200mm working distance is found.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-50S the Right Cylinder?
This Ø140mm model delivers 1570kgf maximum push at 1.0MPa. If you need less power, stepping down to a Ø125 bore provides 1251kgf max push, while moving up to a Ø160 bore yields 2050kgf. Choose this adjustable version when setups require frequent end-position changes without swapping parts; otherwise, a fixed-stroke ACQ is simpler. Confirm your ordering details: 140mm bore, 200mm full stroke, 50mm window, -S magnet for sensors, and the default M22x2.5 female 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 ACQJ140X200-50S FAQ
It provides 7696.9N push and 7294.8N pull at 0.5MPa, 10775.7N push at 0.7MPa, and a maximum push of 1570kgf at 1.0MPa. The 200mm stroke features a 50mm window, allowing the extend distance to be fine-tuned between 150mm and 200mm.
An external threaded stop limits forward travel without altering piston area, so force remains identical to a standard ACQ. The cylinder uses fixed NBR bumpers for deceleration, not an adjustable air cushion. Note that it will not hold a load on air loss; use an external rod lock for fail-safe positioning.
