Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-75SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-75SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 75mm 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 ACQJ160X75-75SB
The AirTAC ACQJ160X75-75SB is a double-acting JIS compact cylinder from the big-bore range, featuring a 160mm bore and 75mm full stroke. An external threaded stop with a lock nut limits the extend end position, yielding a usable extension range of 0-75mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area stays constant, output force equals a standard ACQ of this identical bore.
Operating pressure spans 0.15-1.0 MPa, generating 10053.1N push and 9424.8N pull at 0.5 MPa. This unit includes a male M36x1.5 rod end for direct coupling and a piston magnet for reed or solid-state switches. Deceleration relies on a fixed NBR elastomer bumper at each end rather than an adjustable air cushion, making external shock absorbers advisable for high-energy loads.

| Bore size | Ø160 mm |
| Full stroke | 75 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 |

| 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 ACQJ160X75-75SB Is Used
Heavy Press Tonnage Varying
Dial in the exact extension distance on a large metalforming press during die-changeover without swapping the cylinder, shortening the 75mm stroke as needed for new part heights.
Large Lift Platform Setup
Fine-tune the raised stop position on a heavy-duty lifting rig, using the external M36x2.0 adjuster to set the platform height precisely between 0 and 75mm.
Industrial Pallet Positioning
Adjust the end-of-stroke pusher location on a packaging conveyor to handle different pallet depths, relying on the fixed elastomer bumper to absorb the high kinetic energy.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-75SB the Right Cylinder?
Selecting this 160mm bore provides a 14074.3N push at 0.7 MPa, whereas stepping down to a 140mm bore yields 10775.7N push, and no larger standard bore exists in this series. If your extension endpoint never varies, a fixed-stroke ACQ cylinder suffices. When ordering, confirm the 160mm bore, 75mm full stroke, 75mm adjustment window, the -S magnet requirement, and the -B male M36x1.5 rod thread.
Quick checklist

- ✓ 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 ACQJ160X75-75SB FAQ
It delivers 10053.1N push and 9424.8N pull at 0.5 MPa, 14074.3N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 75mm with a 75mm adjustment window, allowing a usable extend range of 0-75mm. The external adjuster uses an M36x2.0 thread.
The external threaded stop and lock nut mechanically limit the extend stroke without changing the piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected. The cylinder uses a fixed NBR bumper for deceleration, not a brake; a plain ACQ-type will not hold its load on air loss, so an external rod lock or pilot-operated check valve is required for fail-safe holding.
