Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-30S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-30S 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 ACQJ160X50-30S
The AirTAC ACQJ160X50-30S is a JIS compact double-acting single-rod cylinder engineered for big-bore tasks, featuring a 50 mm total stroke and an external threaded stop with a lock nut. This mechanism lets you fine-tune the extend end position directly on the machine, yielding a usable extend range of 20-50 mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, output force is identical to a standard ACQ of this bore, generating 10053.1 N push at 0.5 MPa. The design incorporates fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. Equipped with a -S magnet, the unit operates seamlessly with reed or solid-state electronic switches for precise position sensing via its integrated grooves.

| 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 ACQJ160X50-30S Is Used
Press Tonnage Trial
Validate clamping force on a heavy stamping press by incrementally adjusting the extend stop within the 20-50 mm window during setup.
Large Fixture Changeover
Accommodate varying jig heights on a multi-model assembly line by turning the external stopper instead of swapping out entire cylinders.
Heavy Platen Leveling
Dial in the exact extended contact point for a massive lifting platen on the factory floor without disassembling the pneumatic rig.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-30S the Right Cylinder?
For lower force needs, an ACQJ140 provides 7696.9 N push at 0.5 MPa, whereas this 160 mm bore hits 10053.1 N. If your setup never requires end-position tuning, a fixed-stroke ACQ cylinder is simpler and sufficient. When ordering, verify the 50 mm full stroke, the 30 mm adjustment window, the -S magnet option, and the default female M24x3.0 rod-end thread. Remember that a plain ACQ-type cylinder will not hold its load on air loss; add an external rod lock or pilot-operated check valve for fail-safe holding.
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 ACQJ160X50-30S FAQ
It features a 160 mm bore, a 50 mm full stroke, and a 30 mm adjustment window, giving a usable extend range of 20-50 mm. The force is identical to a standard ACQ: 10053.1 N push and 9424.8 N pull at 0.5 MPa, 14074.3 N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The port size is PT3/8.
An external M36x2.0 threaded stop with a lock nut limits the extend stroke, allowing on-machine tuning without changing parts. The retract stroke is unaffected, and because the piston area is unchanged, force is not reduced. The cylinder uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions, so you should slow the approach or add an external shock absorber for high-energy loads.
