Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-100SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-100SB 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 ACQJ140X200-100SB
The AirTAC ACQJ140X200-100SB represents the big-bore JIS compact line, engineered for double-acting operation with an external mechanical extend stop. A threaded adjuster featuring an M27x2.0 thread and lock nut lets you dial in the forward end position on the machine itself. With a 100mm window subtracted from the 200mm base travel, your usable forward motion spans 100-200mm. The return trip remains fixed at its original length.
Because the internal piston area stays constant, output thrust matches a standard ACQ exactly: 7696.9N push and 7294.8N pull at 0.5MPa. This Ø140mm unit integrates an NBR fixed elastomer bumper at each end to absorb kinetic energy, rather than relying on adjustable pneumatic cushioning. The -S option equips a piston magnet compatible with reed or solid-state electronic switches, while the -B option supplies a male M30x1.5 rod end for direct load coupling.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-100SB Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-100SB |
|---|---|
| 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 ACQJ140X200-100SB Is Used
Press Tonnage Trials
Dialing in exact material deformation on a large press. The external stop allows operators to test intermediate clamp depths between 100 and 200mm without swapping mechanical spacers.
Heavy Fixture Changeover
Adapting automated welding stations for new pallet dimensions. The lock nut enables rapid forward limit reconfiguration to accommodate different sub-assembly heights.
Lift Station Calibration
Setting precise upper elevation stops on heavy-duty pallet lifts. Technicians can tune the 100-200mm extension window on-site to perfect the discharge height.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-100SB the Right Cylinder?
If your process requires less thrust, the Ø125 bore yields 6135.9N push at 0.5MPa; stepping up to Ø160 provides 10053.1N. A non-adjustable ACQ is preferable when your end position never varies. For this model, verify your order specifies the 140mm bore, 200mm full travel, 100mm adjustment window, S magnet, and B 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 ACQJ140X200-100SB FAQ
At 0.5MPa it delivers 7696.9N push and 7294.8N pull; at 0.7MPa push is 10775.7N; maximum push is 1570kgf at 1.0MPa. The full stroke is 200mm, and with the 100mm window, the usable extend range is 100-200mm. Retract stroke is unaffected.
No, the adjuster only changes the forward stroke length, leaving piston area and force identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers at each end, not adjustable air cushions. For high-speed loads, add an external shock absorber. Note that a plain compact cylinder will drift if air pressure is lost; use an external rod lock for fail-safe holding.
