Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-30SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-30SB 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 ACQJ140X200-30SB
The ACQJ140X200-30SB is a double-acting JIS compact cylinder featuring a big 140mm bore and an external extend stop. A threaded rod with a lock nut lets you dial the forward end position anywhere within a 170 to 200mm range on the machine, skipping custom parts. The return stroke remains fixed at the full 200mm.
Because the piston area is untouched, output force equals a standard ACQ of this size, delivering 7696.9N push at 0.5MPa. This SB variant includes a male M30x1.5 rod end for direct load coupling and a piston magnet compatible with reed or solid-state switches. Fixed NBR elastomer bumpers absorb end-of-stroke impact across the 30-500mm/s speed range.

| 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 ACQJ140X200-30SB Is Used
Press Fit Tuning
Dialing in the exact extend position during a press-fit operation on an automotive assembly line without machining new spacer collars.
Product Family Changeover
Shifting the forward stop by a few millimeters on a packaging line to accommodate a new carton size rapidly.
Prototype End Stops
Testing various extend endpoints on a heavy-duty testing rig to find the optimal contact distance before finalizing a design.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-30SB the Right Cylinder?
If you need less thrust, the 100mm bore yields 3927.0N push at 0.5MPa, whereas stepping up to the 160mm bore provides 10053.1N. Choose this 140mm body when your fixture requires roughly 7696.9N of push force and on-the-fly forward position tuning. If the extend endpoint never varies, a fixed-stroke ACQ cylinder is sufficient. Confirm your ordering essentials: 140mm bore, 200mm full stroke, 30mm adjust window, male rod thread, and the magnet option.
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 ACQJ140X200-30SB FAQ
It delivers 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 full stroke is 200mm, and the external stop provides a usable extend range of 170-200mm (a 30mm window).
No, the adjuster only changes the extend length, leaving the piston area and force identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration; for high-energy loads, use an external shock absorber or slow the approach.
