Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-100S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-100S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm bore and 100mm 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 ACQJ140X100-100S
The AirTAC ACQJ140X100-100S is a double-acting JIS compact cylinder featuring a big-bore 140 mm body and an external extend stop. A threaded rod with a lock nut lets you set the extend end position on the machine, providing a usable extend range of 0-100 mm from the 100 mm full stroke. The retract distance remains fixed. Because the piston area is unchanged, output force equals a standard ACQ of this size.
This unit pushes 7696.9 N and pulls 7294.8 N at 0.5 MPa, reaching 10775.7 N at 0.7 MPa with a 1570 kgf maximum. It uses a PT3/8 port, a 32 mm rod with an M22x2.5 female thread, and an M27x2.0 adjuster thread. Fixed NBR elastomer bumpers handle end deceleration, while the -S magnet enables position sensing with reed or solid-state switches.

| 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 (Ø140mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 7697 N | 7295 N |
| 0.7 MPa | 10776 N | — |
| Max (@1.0 MPa) | 1570 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 ACQJ140X100-100S Is Used
Heavy Press Tonnage Setup
Dial in the exact 0-100 mm extend position during press tooling changes without machining new spacers.
Automotive Welding Changeover
Shift the extend stop rapidly when swapping robotic welding fixture heights for different vehicle platforms.
Large Mold Clamping
Test varying clamping end positions on large injection molds to find the optimal grip depth before locking the nut.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-100S the Right Cylinder?
For lower force needs, the 100 mm bore yields 3927.0 N push at 0.5 MPa; if you need more, the 160 mm bore provides 10053.1 N. Choose this 140 mm bore if your fixture demands roughly 7696.9 N of push force with on-site stroke tuning. If the extend position never varies, a fixed-stroke ACQ suffices. When ordering, confirm the 100 mm full stroke, the 100 mm adjustment window, the -S magnet, and the M22x2.5 female 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 ACQJ140X100-100S FAQ
It delivers 7696.9 N push and 7294.8 N pull at 0.5 MPa, 10775.7 N push at 0.7 MPa, and a 1570 kgf max push. The full stroke is 100 mm with a 100 mm window, yielding a usable extend range of 0-100 mm. The retract stroke is unaffected.
An external M27x2.0 threaded stop with a lock nut limits the extend distance without changing the piston area, so force remains identical to a standard ACQ. Fixed NBR elastomer bumpers decelerate the load at stroke ends; for high energy, add an external shock absorber. A plain ACQ does not hold its load on air loss, so use an external rod lock for fail-safe holding.
