Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-50S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm 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 ACQJ160X100-50S
The AirTAC ACQJ160X100-50S is a double-acting, single-rod JIS compact cylinder from the big-bore range, featuring an external threaded stop with a lock nut that limits the extend end position. With a full stroke of 100 mm and a 50 mm adjustment window, you can fine-tune the usable extend travel anywhere between 50 mm and 100 mm directly on the machine. The retract stroke remains completely unaffected by this mechanism.
Because the piston area stays constant, output force is identical to a standard ACQ of the same size, delivering 10053.1 N push and 9424.8 N pull at 0.5 MPa. The Ø40 mm rod uses an M24x3.0 female thread, and the R adjuster features an M36x2.0 thread. NBR elastomer bumpers fixed at each end handle end-of-travel deceleration, while the integrated -S magnet works seamlessly with reed or solid-state sensors.

| Speed range | 30 – 500 mm/s |
| Rod thread | M24×3.0 (F) / M36×1.5 (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 (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 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 ACQJ160X100-50S Is Used
Heavy Press Tonnage Setup
Dial in the exact extend position on a 160 mm metal-forming press during initial tooling setup, allowing 50 to 100 mm of travel to find the optimal striking depth without machining new spacers.
Large Fixture Changeover
Adapt automated assembly lines for new product variants by turning the external M36x2.0 stop nut, quickly resetting the extend endpoint to match different large fixture heights.
Clamp Position Tuning
Test and establish trial end positions for heavy-duty clamping mechanisms, relying on the unchanged 10053.1 N push force at 0.5 MPa to secure parts while adjusting the stroke window.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-50S the Right Cylinder?
When sizing this big-bore 160 mm unit, dropping down to a 125 mm bore yields 6135.9 N push at 0.5 MPa, whereas stepping up is unavailable within this compact series. If your application never requires stroke adjustments, a fixed-stroke ACQ cylinder provides the same holding power without the external adjuster. To order this adjustable model correctly, confirm the 160 mm bore, 100 mm full stroke, 50 mm window, -S magnet for sensing, and the default 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 ACQJ160X100-50S FAQ
This cylinder delivers a push force of 10053.1 N and a pull force of 9424.8 N at 0.5 MPa, 14074.3 N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The usable extend range is 50-100 mm, achieved by shortening the 100 mm full stroke via the 50 mm adjustment window.
No, the adjuster changes only the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The retract stroke is entirely unaffected. End-of-travel deceleration relies on fixed NBR elastomer bumpers, so for high-energy loads, an external shock absorber is recommended. Note that on air loss, a plain ACQ-type cylinder does not hold its load; use an external rod lock or pilot-operated check valve for fail-safe holding.
