Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-50S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 125mm 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 ACQJ160X125-50S
The AirTAC ACQJ160X125-50S represents the big-bore JIS compact adjustable-stroke series, engineered for double-acting single-rod operations. An external threaded stop with a lock nut on the rod-end side restricts the EXTEND end position. With a full stroke of 125 mm and a 50 mm window, the usable extend range spans 75 to 125 mm. The RETRACT stroke remains completely unaffected by this mechanism.
Because the piston area stays constant, the output force is identical to a standard ACQ of this bore, yielding 10053.1 N push and 9424.8 N pull at 0.5 MPa. The unit features a fixed NBR elastomer bumper at each end for end-of-stroke deceleration, and the included -S magnet enables position detection via reed or electronic solid-state switches.

| Bore size | Ø160 mm |
| Full stroke | 125 mm |
| Adjuster thread | M36×2.0 |
| 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 | M24×3.0 (F) / M36×1.5 (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 (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 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 ACQJ160X125-50S Is Used
Press Tonnage Adjustment
Dial in the exact extend distance from 75 to 125 mm on heavy metal stamping presses without swapping out components during product changeovers.
Heavy Conveyor Diverter
Set precise actuation endpoints for large package diverters on high-capacity assembly lines, allowing rapid 50 mm stroke shortening for varying pallet sizes.
Lift Platform Positioning
Establish trial end positions for vertical lifting mechanisms in automated warehousing, tweaking the extend limit on the machine without disassembling the cylinder.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-50S the Right Cylinder?
When sizing this big-bore 160 mm unit, consider the neighbouring capacities: a 140 mm bore provides 7696.9 N push at 0.5 MPa, while this 160 mm variant delivers 10053.1 N. If your application does not require on-the-fly extend position tuning, a fixed-stroke ACQ cylinder will suffice. When ordering, confirm the 160 mm bore, 125 mm full stroke, 50 mm adjustable window, the -S magnet option, and the default female rod-end thread (M24x3.0).
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 ACQJ160X125-50S FAQ
The push force is 10053.1 N and pull is 9424.8 N at 0.5 MPa (14074.3 N push at 0.7 MPa), with a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 125 mm with a 50 mm window, providing a usable extend range of 75 to 125 mm. The external adjuster (R) thread is M36x2.0.
The external threaded stop with lock nut limits only the extend stroke length, leaving the retract stroke unaffected. Because the piston area is unchanged, the force remains identical to a standard ACQ. The fixed NBR elastomer bumper decelerates the load near stroke end, but a plain ACQ does not hold the load on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve.
