Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-40S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-40S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 50mm 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 ACQJ160X50-40S
The AirTAC ACQJ160X50-40S is a double-acting JIS compact cylinder from the big-bore range, featuring a 160mm bore and 50mm full stroke. An external threaded stop with a lock nut limits the extend end position, allowing you to fine-tune the usable extend stroke anywhere from 10mm up to the full 50mm directly on the machine. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the force output is identical to a standard ACQ of this size, delivering 10053.1N push at 0.5 MPa. The cylinder uses a PT3/8 port, a 40mm piston rod, and a fixed elastomer bumper at each end for deceleration. Equipped with a piston magnet (-S), it supports both reed and solid-state electronic switches for position sensing.

| Adjuster thread | M36×2.0 |
| Port size | PT3/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| 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 ACQJ160X50-40S Is Used
Heavy Press Tonnage Setup
Dial in the exact 10 to 50mm extend contact point during heavy press changeovers without machining new spacer blocks.
Large Fixture Positioning
Adapt end-stop limits on large welding fixtures to accommodate varying metal workpiece thicknesses on the fly.
Molding Machine Trial
Establish precise trial end positions for mold closing or holding routines before finalizing hard mechanical stops.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-40S the Right Cylinder?
For lower force needs, the 140mm bore provides 7696.9N push @0.5MPa, while stepping up is not available in this compact series as 160mm is the largest big-bore option. If exact extend positioning is unnecessary, a fixed-stroke ACQ cylinder will suffice. When ordering, verify the 160mm bore, 50mm full stroke, 40mm adjustable window, the -S magnet, and the female M24x3.0 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 ACQJ160X50-40S 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 usable extend range is 10-50mm (50mm full stroke minus up to a 40mm window).
No, the external M36x2.0 adjuster only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The rod drifts on air loss as the fixed NBR bumper only decelerates near the stroke end; use an external rod lock for fail-safe holding.
