Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X150-50S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X150-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm bore and 150mm 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 ACQJ125X150-50S
The AirTAC ACQJ125X150-50S is a double-acting JIS compact cylinder featuring a big-bore 125 mm piston and an external extend stop mechanism. By turning the M27x2.0 adjuster screw with its lock nut, operators can fine-tune the extend end position on the machine, yielding a usable forward range of 100-150 mm. The retract distance remains completely unaffected. Because the adjuster solely restricts forward travel without altering the internal piston area, generated force stays identical to a standard ACQ of this size.
This robust unit delivers 6135.9 N push and 5733.8 N pull force at 0.5 MPa, scaling to 8590.3 N push at 0.7 MPa, with a maximum push capacity of 1251 kgf at 1.0 MPa. It incorporates a 32 mm piston rod, a PT3/8 port, and fixed NBR elastomer bumpers at each end to absorb impact energy. The -S magnet option enables compatibility with both reed and electronic solid-state switches via the integrated mounting grooves.

| 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 ACQJ125X150-50S Is Used
Multi-Part Machining Fixtures
Accommodate varying raw material lengths on a single CNC station by dialing the extend stop back from 150 mm to 100 mm, eliminating the need for custom spacer plates.
Carton Changeover Stops
Rapidly adjust the end position for different box sizes on a packaging line, using the external M27x2.0 lock nut to set precise 100 to 150 mm tucking strokes.
Press Trial Positions
Safely test new forming depths on heavy press equipment by gradually increasing the forward travel in increments, ensuring the 6135.9 N force hits the target without overtravel.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X150-50S the Right Cylinder?
When sizing this 125 mm bore model, consider the adjacent big-bore compact options. Stepping down to a 100 mm bore drops the 0.5 MPa push force to 3927.0 N, while stepping up to a 140 mm bore increases it to 7696.9 N. If your process requires a single, unchanging forward position, a standard fixed-stroke ACQ cylinder is sufficient and simpler. If your fixtures vary or you need rapid product changeover, this ACQJ125X150-50S provides the necessary 100-150 mm forward tuning window. To order, confirm the 125 mm bore, 150 mm full stroke, 50 mm adjustment window, the -S magnet option, and the default female M22x2.5 rod-end 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 ACQJ125X150-50S FAQ
It provides 6135.9 N push and 5733.8 N pull force at 0.5 MPa, 8590.3 N push at 0.7 MPa, and a maximum push of 1251 kgf at 1.0 MPa. The full stroke is 150 mm, and with the 50 mm adjustment window, the usable extend range is 100-150 mm. The retract stroke remains fixed at 150 mm.
The external M27x2.0 threaded stop screw and lock nut mechanically limit how far the rod extends, shortening the forward travel without changing the piston area, so force is identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions. Note that a plain ACQ-type does not hold its load on air loss; for a fail-safe hold, use an external rod lock or pilot-operated check valve.
