Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-75SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-75SB 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 ACQJ160X300-75SB
The AirTAC ACQJ160X300-75SB is a double-acting JIS compact cylinder from the big-bore range, featuring a 300mm full stroke and an external extend stop. A threaded adjuster with a lock nut lets you fine-tune the extend end position on the machine, providing a usable forward range of 225-300mm without swapping parts. The retract stroke remains completely unaffected. Because the piston area stays the same, output force is identical to a standard ACQ of this bore.
This 160mm bore unit delivers 10053.1N push and 9424.8N pull force at 0.5MPa, peaking at 2050kgf max push at 1.0MPa. It includes an M36x1.5 male piston rod for direct load coupling, PT3/8 ports, and a built-in magnet compatible with reed or solid-state switches. Fixed NBR elastomer bumpers decelerate the load at both ends, though external shock absorbers are suggested for high-energy approaches.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-75SB Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-75SB |
|---|---|
| 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 ACQJ160X300-75SB Is Used
Heavy Press Tooling
Dial in the exact clamping depth on large metal stamping presses during die-changeover without machining custom spacers.
Automated Assembly Stops
Vary the extend position on multi-model assembly lines to accommodate different product lengths on the fly.
Platen Positioning
Establish trial end positions for large molding or forming platens, tweaking the 225-300mm usable range to find optimal contact.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-75SB the Right Cylinder?
Selecting this 160mm bore actuator means requiring massive thrust in a riveted body format rather than a tie-rod build. If you do not need on-machine end-position tuning, a standard fixed-stroke ACQ cylinder suffices. For slightly less force, the 140mm bore yields 7696.9N push at 0.5MPa, while this 160mm unit provides 10053.1N push at 0.5MPa. Confirm your ordering essentials: 160mm bore, 300mm full stroke, 75mm adjuster window, plus the -S magnet and -B male rod thread options.
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 ACQJ160X300-75SB FAQ
This cylinder provides 10053.1N push and 9424.8N pull force at 0.5MPa, 14074.3N push at 0.7MPa, and a maximum push of 2050kgf at 1.0MPa. The full stroke is 300mm, but with the 75mm window, the usable extend range is 225-300mm.
An external M36x2.0 threaded stop with a lock nut limits the forward extension, changing only the stroke length, not the piston area, so force remains identical to a standard ACQ. Fixed elastomer bumpers decelerate the load near stroke end. 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.
