Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X125-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X125-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm bore and 125mm 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 ACQJ125X125-10SB
The ACQJ125X125-10SB is a double-acting JIS compact cylinder featuring a big-bore 125mm body and an external extend stop. A threaded adjuster with a lock nut lets you fine-tune the extend stroke from 115mm up to the full 125mm directly on your machinery. The retract distance remains completely unaffected by this adjustment. Because the piston area stays constant, the output force is identical to a standard ACQ of this size, yielding 6135.9N push at 0.5MPa.
This variant includes a male M30x1.5 piston rod end for direct load coupling and a built-in magnet (-S) for position sensing. It uses a fixed NBR elastomer bumper at each end for end-of-travel deceleration rather than an adjustable air cushion. The standard PT3/8 port and 32mm rod diameter handle heavy loads, while the M27x2.0 adjuster thread securely locks the desired position.

| 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 | M22×2.5 (F) / M30×1.5 (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 (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 6136 N | 5734 N |
| 0.7 MPa | 8590 N | — |
| Max (@1.0 MPa) | 1251 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 ACQJ125X125-10SB Is Used
Press Tooling Changeovers
Adapt forming dies on heavy stamping presses by dialing in the 115-125mm extend limit to accommodate varying material thicknesses without swapping hardware.
Large Assembly Jigs
Set precise clamping endpoints for oversized automotive sub-assemblies, utilizing the 1251kgf maximum push to secure heavy structural components.
Palletizing Stops
Adjust the pusher end position on the fly to handle varying pallet sizes or box depths, ensuring consistent alignment during high-speed wrapping.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X125-10SB the Right Cylinder?
If 6135.9N push at 0.5MPa is excessive, stepping down to the 100mm bore drops the push force to 3927.0N. Conversely, upgrading to the 160mm bore raises the 0.5MPa push to 10053.1N for heavier demands. If you never need to alter the end position, a fixed-stroke ACQ cylinder suffices. When ordering this unit, verify the 125mm bore, 125mm full stroke, 10mm window, -S magnet, and -B male rod thread.
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 ACQJ125X125-10SB FAQ
It provides 6135.9N push and 5733.8N pull at 0.5MPa, 8590.3N push at 0.7MPa, and a maximum push of 1251kgf at 1.0MPa. The full stroke is 125mm, but the external stop allows you to shorten the extend range to 115-125mm.
An external M27x2.0 threaded screw with a lock nut limits the extend distance without changing the piston area, so force remains identical to a standard ACQ. Deceleration relies on a fixed NBR elastomer bumper, not an adjustable air cushion. The -S magnet supports both reed and electronic solid-state switches for end-position detection.
