Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-30SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 150mm 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 ACQJ160X150-30SB
The AirTAC ACQJ160X150-30SB is a double-acting, single-rod JIS compact cylinder engineered for big-bore tasks, featuring a 150 mm full stroke and a male-thread piston rod end (M36x1.5). An external threaded stop with a lock nut restricts the extend end position, providing a usable forward range of 120 to 150 mm. The retract stroke remains completely unaffected by this adjustment. Because the internal piston area stays constant, output force equals that of a standard ACQ of the same bore, yielding 10053.1 N of push force at 0.5 MPa.
This big-bore variant integrates fixed elastomer bumpers at each end to decelerate the load near the stroke limits rather than relying on adjustable air cushions. The built-in piston magnet (-S) supports both reed and solid-state electronic switches via the standard grooves. Operating pressure spans 0.15 to 1.0 MPa, and the PT3/8 porting matches the substantial 40 mm rod diameter. For high-energy cycles, consider adding an external shock absorber to protect the fixed NBR bumper.

| 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 ACQJ160X150-30SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 120 to 150 mm extend position on a heavy-duty press without swapping cylinders during tooling changes.
Large Mold Changeover
Adapt the forward stop depth rapidly for different large injection molds or forming dies directly on the machine frame.
Structural Ram Positioning
Test and set precise end positions for structural rams in heavy fabrication before finalizing the mechanical hard stop.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-30SB the Right Cylinder?
Choosing this 160 mm bore provides a maximum push capacity of 2050 kgf at 1.0 MPa. If your application requires less force, stepping down to a 140 mm bore drops the push force to 7696.9 N at 0.5 MPa, while moving up is impossible as 160 mm is the largest available standard bore in this compact series. If you do not need to modify the end position on the fly, a fixed-stroke ACQ cylinder will suffice. When ordering, verify the bore, 150 mm full stroke, 30 mm adjuster window, -S magnet, and -B male rod thread.

- ✓ 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 ACQJ160X150-30SB 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 150 mm with a 30 mm window, allowing an adjustable extend range of 120 to 150 mm. The retract stroke is unaffected.
The M36x2.0 external threaded stop and lock nut limit only the extend length, meaning force remains identical to a standard ACQ since piston area is unchanged. Fixed elastomer bumpers decelerate movement at the ends, but a plain cylinder will not hold a load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
