Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-40SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-40SB 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 ACQJ140X200-40SB
The AirTAC ACQJ140X200-40SB is a double-acting JIS compact cylinder featuring an external M27x2.0 threaded stop with a lock nut on the extend side. This mechanism lets you fine-tune the extend end position directly on your equipment, providing a usable extend range of 160 to 200 mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore, delivering 7696.9 N push and 7294.8 N pull at 0.5 MPa. This big-bore variant includes a male M30x1.5 rod-end thread for direct load coupling, a fixed NBR elastomer bumper at each end, and a built-in piston magnet for position sensing.

| 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 ACQJ140X200-40SB Is Used
Heavy Press Tuning
Dial in the exact 160-200 mm extend position during heavy press setup without machining custom spacers or swapping components.
Automotive Product Changeover
Quickly adjust the extend stop for varying chassis dimensions on an automotive assembly line during model transitions.
Large Pallet Positioning
Fine-tune the end-of-stroke contact point for oversized pallets in packaging lines to accommodate different box heights.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-40SB the Right Cylinder?
If you need slightly less thrust, the 100 mm bore yields 3927.0 N push at 0.5 MPa, whereas moving up is not an option as 140 mm is a large-body variant. If your application never requires end-position variance, a fixed-stroke ACQ cylinder will suffice. When ordering this unit, verify the 140 mm bore, 200 mm full stroke, 40 mm adjuster window, male rod thread, and magnet presence.
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 ACQJ140X200-40SB FAQ
At 0.5 MPa, push force is 7696.9 N and pull force is 7294.8 N; at 0.7 MPa, push is 10775.7 N. The maximum push at 1.0 MPa is 1570 kgf. The usable extend range is 160 to 200 mm, set by the 40 mm adjustment window.
The external M27x2.0 threaded stop limits only the extend stroke length, meaning force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration, not an adjustable air cushion. Note that a plain ACQ-type does not hold its load on air loss; for a fail-safe hold, use an external rod lock or pilot-operated check valve.
