Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X75-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X75-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm 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 ACQJ125X75-10S
The AirTAC ACQJ125X75-10S is a double-acting JIS compact cylinder featuring a 125mm bore and a 75mm full stroke. An external M27x2.0 threaded stop with a lock nut limits the extend end position, providing a usable extend range of 65 to 75mm. The retract stroke remains unaffected by this adjustment. Because the piston area is unchanged, output force is identical to a standard ACQ of this size.
This big-bore variant delivers 6135.9N push and 5733.8N pull at 0.5MPa. It includes a built-in piston magnet (-S) compatible with reed or electronic solid-state switches. The body uses fixed NBR elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions. Operating pressure ranges from 0.15 to 1.0MPa, with a PT3/8 port and a 32mm rod.

| 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 ACQJ125X75-10S Is Used
Heavy Press Tonnage Setup
Dial in the exact 65-75mm extend reach on a large stamping press during initial tool setup, preventing over-travel without machining new spacers.
Automated Welding Line Changeover
Quickly reposition a heavy welding head for different automotive chassis frames by turning the external M27x2.0 stopper to shift the endpoint.
Large Fixture Positioning
Fine-tune clamping reach on massive machining fixtures, accommodating part tolerances on the fly while maintaining full 6135.9N clamping force.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X75-10S the Right Cylinder?
Choosing this 125mm bore provides 6135.9N push at 0.5MPa; stepping down to a 100mm bore yields 3927.0N, while a 140mm bore offers 7696.9N. A fixed-stroke ACQ is sufficient if your extend end position never requires tweaking. When ordering, confirm the 75mm full stroke, 10mm adjustment window, magnet option, and female M22x2.5 rod-end 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 ACQJ125X75-10S FAQ
It delivers 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 75mm with a 10mm adjustment window, giving a usable extend range of 65-75mm.
The M27x2.0 threaded stop with lock nut mechanically limits the extend length without altering piston area, so force remains identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. Note that a plain compact cylinder will drift on air loss; use an external rod lock for fail-safe load holding.
