Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X50-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X50-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm bore and 50mm 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 ACQJ125X50-10S
The AirTAC ACQJ125X50-10S represents the big-bore JIS compact pneumatic line, engineered for double-acting operation with a single rod. An external M27x2.0 threaded stop and lock nut restricts the forward extend position, providing a usable extend range of 40-50mm from the 50mm full stroke. The retract movement remains completely unaffected by this adjustment.
Because the internal piston area stays constant, output force equals a standard ACQ of identical bore, yielding 6135.9N push and 5733.8N pull at 0.5MPa. The unit integrates fixed NBR elastomer bumpers at each end for end-of-travel deceleration rather than adjustable air cushions. Equipped with a -S magnet, the cylinder operates seamlessly with both reed and electronic solid-state sensors.

| Adjuster thread | M27×2.0 |
| Port size | PT3/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| 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 ACQJ125X50-10S Is Used
Press Tonnage Setup
Vary the extend stop within the 40-50mm window to test different material forming depths on a single stamping press without machining new spacers.
Package Divert Finesse
Alter the pusher rod extension by up to 10mm during product changeover to gently handle varying box sizes on a high-speed sorting line.
Bending Trial Positions
Dial in the exact end-of-stroke contact point for prototype metal bending fixtures, allowing rapid iteration of bend angles without swapping cylinders.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X50-10S the Right Cylinder?
When sizing this 125mm bore, dropping to the 100mm bore reduces push force to 3927N at 0.5MPa, whereas stepping up to the 160mm bore increases push to 10053.1N. If your machine never requires on-site end-position tuning, a fixed-stroke ACQ cylinder provides the same holding power in a simpler package. To order this adjustable variant, confirm the 125mm bore, 50mm full stroke, 10mm adjustment window, -S magnet requirement, and the default 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 ACQJ125X50-10S FAQ
This cylinder 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 50mm with a 10mm adjustment window, resulting in a usable extend range of 40-50mm.
The external M27x2.0 threaded stop with a lock nut mechanically limits how far the rod extends, shortening the forward stroke without altering the piston area, so force remains identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers at both ends, not adjustable air cushions; for high-energy loads, add an external shock absorber.
