Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-50S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-50S 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 ACQJ140X100-50S
The AirTAC ACQJ140X100-50S is a double-acting JIS compact cylinder featuring a 140mm bore and a 100mm full stroke. An external threaded stop with a lock nut lets you fine-tune the extend end position on the machine, providing a usable extension range of 50-100mm. The retract stroke remains completely unaffected by this adjustment. Built-in NBR elastomer bumpers decelerate the moving load at each end, and the included piston magnet works seamlessly with reed or solid-state switches.
Because the adjustment mechanism only limits travel length and does not alter the piston area, the output force matches a standard ACQ of the same size. At 0.5 MPa, it delivers 7696.9N of push force and 7294.8N of pull force, climbing to 10775.7N push at 0.7 MPa. The maximum push capacity reaches 1570 kgf at 1.0 MPa. This big-bore compact variant utilizes a PT3/8 port, a 32mm piston rod, and an M27x2.0 adjuster thread.

| 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 ACQJ140X100-50S Is Used
Press Tooling Changeovers
Adapt large metal-forming presses rapidly by dialing in the 50-100mm extend range to meet varying die heights without machining custom spacers.
Heavy Material Positioning
Index heavy structural components on automated welding lines, using the external stop to tweak push distances for different assembly profiles.
Oversized Crate Handling
Regulate the extension stroke on large palletizing equipment to accommodate varying package dimensions while relying on the fixed elastomer bumper for end-of-travel deceleration.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-50S the Right Cylinder?
When sizing this 140mm bore actuator, dropping to the 125mm bore reduces the 0.5 MPa push force to 6135.9N, whereas stepping up to the 160mm bore increases it to 10053.1N. If your equipment never requires altering the end-of-stroke position, a fixed-stroke ACQ cylinder will provide identical holding power and simpler setup. To order correctly, confirm the 140mm bore, 100mm full stroke, 50mm adjustable window, the -S magnet option, 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 ACQJ140X100-50S FAQ
This double-acting cylinder provides 7696.9N push and 7294.8N pull force at 0.5 MPa, and 10775.7N push at 0.7 MPa. The maximum push force is 1570 kgf at 1.0 MPa. The full stroke is 100mm, but the external adjuster allows you to shorten the extend travel by up to 50mm, yielding a usable extend range of 50-100mm.
No, the output force remains identical to a standard ACQ of the same 140mm bore because the piston area is unchanged; the adjuster only limits the extension length. The cylinder uses fixed NBR elastomer bumpers for deceleration rather than adjustable air cushions. Additionally, the -S magnet option supports both reed and electronic solid-state switches.
