Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 40mm 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 ACQJ160X40-10S
The ACQJ160X40-10S is a big-bore JIS compact cylinder featuring a 160mm bore and a 40mm full stroke. An external M36x2.0 threaded stop with a lock nut lets you fine-tune the extend end position directly on the machine. With a 10mm adjustment window, the usable extend range runs from 30mm up to 40mm, while the retract stroke remains completely unaffected.
Because the adjuster only limits travel, the piston area stays the same, meaning output force is identical to a standard ACQ of this size. You get 10053.1N push at 0.5 MPa, 9424.8N pull, and a maximum push capacity of 2050 kgf at 1.0 MPa. The body uses fixed elastomer NBR bumpers at each end rather than adjustable air cushions, and the included -S magnet works with both reed and solid-state electronic switches.

| 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 ACQJ160X40-10S Is Used
Press Tonnage Setup
Dial in the exact 30 to 40mm extend reach during heavy press tooling setups, allowing operators to accommodate varying die heights without machining custom spacers.
Automotive Welding Fixtures
Adjust the clamping endpoint on the fly during vehicle model changeovers, ensuring large weld guns hit precise locations on different chassis variants.
Heavy Lifting Stations
Test and set trial end positions for heavy lifting probes in materials handling equipment, tweaking the 10mm window to avoid over-travel into delicate tooling.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-10S the Right Cylinder?
When sizing this 160mm bore actuator, stepping down to a 140mm bore yields 7696.9N push at 0.5 MPa, whereas this unit provides 10053.1N. If you need more power, there is no larger standard bore in this series, so consider dual mounting. If your application never requires altering the extend length, a fixed-stroke ACQ cylinder is simpler and suffices. Confirm ordering essentials: 160mm bore, 40mm full stroke, 10mm window, the -S magnet, and the default female M24x3.0 rod end with PT3/8 port.
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 ACQJ160X40-10S FAQ
It provides 10053.1N push and 9424.8N pull at 0.5 MPa, 14074.3N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 40mm with a 10mm window, giving a usable extend range of 30-40mm.
No, the external M36x2.0 stop limits travel only, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer NBR bumpers at each end instead of adjustable air cushions, so for high-speed impacts you should add an external shock absorber. Note that a plain cylinder does not hold its load on air loss; use an external rod lock for fail-safe holding.
