Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-10S 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 ACQJ140X200-10S
The AirTAC ACQJ140X200-10S is a JIS compact, double-acting single-rod cylinder built for the big-bore range, offering a 200 mm full stroke. An external M27x2.0 threaded stop and lock nut limits the extend end position, yielding a usable extend range of 190-200 mm. The retract stroke remains unaffected by this adjustment. A -S suffix denotes a built-in piston magnet compatible with reed or electronic solid-state switches.
Because the piston area is unchanged, output force is identical to a standard ACQ of the same bore. At 0.5 MPa, it provides 7696.9 N of push and 7294.8 N of pull force. The unit features fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. Operating pressure spans 0.15-1.0 MPa, and the PT3/8 port pairs with a 32 mm rod.

| 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 ACQJ140X200-10S Is Used
Press Tonnage Setup
Dialing in the exact 190-200 mm extend position on a large metal-forming press to accommodate varying material thicknesses without machining custom spacers.
Heavy Fixture Changeover
Adapting automated assembly line stops during product changeovers, allowing operators to externally shift the end position by up to 10 mm for new part geometries.
Bending Machine Trials
Finding the precise rod extension on a heavy-duty tube bender during prototype runs, relying on the 1570 kgf max push to hold the workpiece firmly.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-10S the Right Cylinder?
If your application requires less than 190 mm of extend travel, the ACQJ125X200-10S offers a 0.5 MPa push of 6135.9 N, while stepping up to the ACQJ160X200-10S yields 10053.1 N. When exact end-position tuning is unnecessary, a fixed-stroke ACQ140X200S avoids the external adjuster entirely. To order this big-bore variant, confirm the 140 mm bore, 200 mm full stroke, 10 mm window, -S magnet, and 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 ACQJ140X200-10S FAQ
At 0.5 MPa, push force is 7696.9 N and pull is 7294.8 N; push at 0.7 MPa is 10775.7 N, with a maximum push of 1570 kgf at 1.0 MPa. The full stroke is 200 mm, and the -10 window allows the extend stroke to be shortened by up to 10 mm, giving a usable extend range of 190-200 mm.
The M27x2.0 external threaded stop with a lock nut mechanically limits the extend distance without altering piston area, so force remains identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. A plain ACQ-type cylinder will not hold its load on air loss; for a fail-safe hold, install an external rod lock or pilot-operated check valve.
