Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-75S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-75S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 300mm 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 ACQJ160X300-75S
The ACQJ160X300-75S is a double-acting, single-rod JIS compact cylinder engineered for big-bore applications requiring adaptable extend end positions. An external M36x2.0 threaded stop with a lock nut limits the outward stroke, yielding a usable extension range of 225-300 mm from the 300 mm full stroke. The retract movement remains completely unaffected. Because the piston area stays constant, output force is identical to a standard ACQ of this bore, giving 10053.1 N push at 0.5 MPa.
This Ø160mm variant features a 40mm piston rod, a female M24x3.0 rod-end thread, and PT3/8 ports. It incorporates fixed NBR elastomer bumpers at both ends to decelerate the load near stroke limits. The integrated -S magnet supports both reed and solid-state electronic switches via the body's grooves. Note that a plain compact cylinder drifts upon air loss; utilize an external rod lock for fail-safe load holding.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-75S Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-75S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 300 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 ACQJ160X300-75S Is Used
Heavy Press Tonnage Setup
Dial in the exact 225-300mm extension on a multi-ton metal stamping press during initial tooling setup without machining custom spacers.
Automotive Assembly Changeover
Adapt end-stops rapidly on large robotic welding fixtures when shifting between different vehicle chassis models on the same line.
Large Mold Positioning
Test and set precise trial end positions for heavy industrial molds before final lock-down, ensuring perfect alignment under high force.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-75S the Right Cylinder?
Selecting this 160mm bore provides 10053.1 N push and 9424.8 N pull at 0.5 MPa, escalating to 14074.3 N push at 0.7 MPa, with a maximum push capacity of 2050 kgf at 1.0 MPa. If your application requires less thrust, stepping down to a 140mm bore yields 7696.9 N push at 0.5 MPa, whereas this 160mm unit is the largest available in this compact frame. A non-adjustable ACQ is sufficient if your extend position never requires field adjustments. Confirm your ordering parameters: 160mm bore, 300mm full stroke, 75mm adjuster window, -S magnet, and female 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 ACQJ160X300-75S FAQ
It delivers 10053.1 N push and 9424.8 N pull at 0.5 MPa, 14074.3 N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 300mm with a 75mm adjuster window, allowing an extend range of 225-300mm.
The external M36x2.0 threaded stop physically limits how far the rod extends, shortening the outward stroke without changing piston area, so force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions, and the -S magnet works with reed or solid-state switches.
