Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-30S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-30S 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 ACQJ160X100-30S
The AirTAC ACQJ160X100-30S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut to precisely limit the extend stroke. You can fine-tune the extend end position on the machine without swapping parts, yielding a usable extend range of 70-100 mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays the same, the output force is identical to a standard ACQ of this 160 mm bore, delivering 10053.1 N push and 9424.8 N pull at 0.5 MPa. This big-bore compact variant integrates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The integrated -S magnet enables position detection using either reed or solid-state electronic switches.

| Bore size | Ø160 mm |
| Full stroke | 100 mm |
| 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 ACQJ160X100-30S Is Used
Heavy Press Tonnage Setup
Dial in the exact 70-100 mm extend position during heavy press changeovers without machining new spacer collars.
Automated Welding Line Changeover
Modify robot welding gun reach on the fly to accommodate different automotive chassis frame widths.
Large Panel Bending Trials
Test various bend depths on thick steel plates by tweaking the external stop instead of reprogramming the press.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-30S the Right Cylinder?
For lower thrust requirements, the 140 mm bore yields 7696.9 N push at 0.5 MPa, whereas this 160 mm unit provides 10053.1 N. If your application strictly requires a fixed 100 mm extend stroke without on-the-fly adjustments, a standard ACQ cylinder is sufficient. When ordering, verify the 160 mm bore, 100 mm full stroke, -30 mm window, -S magnet, and the default 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 ACQJ160X100-30S FAQ
At 0.5 MPa, the push force is 10053.1 N and the pull force is 9424.8 N; at 0.7 MPa, push is 14074.3 N, with a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 100 mm with a -30 mm window, giving a usable extend range of 70-100 mm. The port size is PT3/8, the female rod-end thread is M24x3.0, and the external adjuster thread is M36x2.0.
No, the adjuster only changes the extend stroke length, meaning the force remains identical to a standard ACQ of the same bore. Deceleration at stroke ends is handled by fixed NBR elastomer bumpers rather than adjustable air cushions. Note that this plain compact cylinder will not hold its load on air loss; for a fail-safe hold, use an external rod lock or pilot-operated check valve.
