Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-75SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-75SB 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 ACQJ160X150-75SB
The ACQJ160X150-75SB is a big-bore JIS compact pneumatic cylinder featuring a double-acting single rod and an external threaded stop. A lock nut and adjuster screw (M36x2.0 thread) on the rod-end side restricts how far the rod travels outward. This on-machine stop lets you dial the extend stroke down from the full 150 mm to a minimum of 75 mm. The retract movement remains completely unaffected. The piston rod measures 40 mm and includes a male M36x1.5 thread (-B option) for direct load coupling.
Because the adjuster only limits travel length and leaves piston area untouched, output force is identical to a standard ACQ of this size. At 0.5 MPa it yields 10053.1 N push and 9424.8 N pull, reaching 14074.3 N push at 0.7 MPa, with a maximum 2050 kgf push at 1.0 MPa. The body uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. An integrated magnet (-S option) allows tracking by either reed or solid-state electronic switches.

| 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 ACQJ160X150-75SB Is Used
Heavy Press Tonnage Tuning
Dial in the exact extend reach on a large metal-forming press during setup, shortening the stroke by up to 75 mm to accommodate different die heights without swapping cylinders.
Automotive Welding Line Changeover
Reposition the extend end-stop on a body-in-white assembly station to adapt to new vehicle model dimensions, maintaining 10053.1 N of clamping force at 0.5 MPa.
Machinery Prototyping Stops
Establish safe trial end positions on a newly commissioned robotic machining cell, relying on the fixed elastomer bumper to decelerate the 40 mm rod at the end of travel.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-75SB the Right Cylinder?
Selecting this Ø160 unit is appropriate when your fixture requires substantial thrust within a compact envelope, plus variable extend positioning. If you need less power, stepping down to a Ø140 bore provides 7696.9 N push at 0.5 MPa, while moving up to a larger custom frame would exceed this big-bore range. If the end position never varies, a fixed-stroke ACQ series cylinder suffices. To order, confirm the 160 mm bore, 150 mm full stroke, 75 mm adjustable window, male rod thread (-B), and magnet (-S). Note that a plain cylinder drifts on air loss; install an external rod lock or pilot-operated check valve for fail-safe load holding.
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 ACQJ160X150-75SB FAQ
It delivers 10053.1 N push and 9424.8 N pull at 0.5 MPa, and 14074.3 N push at 0.7 MPa. The maximum push is 2050 kgf at 1.0 MPa. The full extend stroke is 150 mm, but the external stop provides a usable extend range of 75-150 mm (a 75 mm window). The retract stroke is unaffected.
The external M36x2.0 threaded stop with a lock nut limits only the outward extend travel, leaving the retract stroke unchanged. Because the piston area remains the same, the force is identical to a standard ACQ cylinder. The unit relies on fixed NBR elastomer bumpers at both ends for deceleration, and the -S magnet works with reed or electronic switches.
