Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 175mm 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 ACQJ160X175-10SB
The AirTAC ACQJ160X175-10SB is a double-acting, single-rod JIS compact cylinder from the big-bore range, featuring a 160mm bore and a 175mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable forward travel range of 165-175mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area is unchanged, the output force is identical to a standard ACQ of this size, yielding 10053.1N push and 9424.8N pull at 0.5MPa.
This unit includes a male-thread piston rod end (M36x1.5) for direct load coupling and a built-in piston magnet (-S) compatible with reed or electronic solid-state switches. It uses PT3/8 ports and relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. Operating pressure spans 0.15-1.0MPa, and the external adjuster utilizes an M36x2.0 thread.

| 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 ACQJ160X175-10SB Is Used
Heavy Press Tooling Setup
Dial in the exact 165-175mm extend end position during initial heavy press tooling setup, preventing the need to machine custom spacer blocks for each new die height.
Automotive Product Changeover
Quickly modify the forward stroke limit on an automotive assembly line during product changeover, accommodating different chassis dimensions without swapping the actuator.
Large Metal Forming Trial
Establish the optimal end-of-stroke contact point on a large metal forming machine by testing intermediate positions within the 10mm window before locking the nut.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-10SB the Right Cylinder?
When sizing this 160mm bore actuator, stepping down to a 140mm bore yields 7696.9N push at 0.5MPa, while this model provides 10053.1N. If your application requires a fixed 175mm extend position every cycle without variation, a standard ACQ cylinder will suffice and simplify setup. To order this adjustable variant correctly, confirm the 160mm bore, 175mm full stroke, 10mm adjustment window, the -S magnet for sensing, and the -B male 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 ACQJ160X175-10SB FAQ
It provides 10053.1N push and 9424.8N pull at 0.5MPa, 14074.3N push at 0.7MPa, and a maximum push of 2050kgf at 1.0MPa. The usable extend range is 165-175mm via an M36x2.0 external adjuster. The unit features PT3/8 ports and an M36x1.5 male rod thread.
The external stop changes the stroke length only, so the output force remains identical to a standard ACQ. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion. Note that a plain compact cylinder does not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
