Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-50S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-50S 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 ACQJ160X50-50S
The AirTAC ACQJ160X50-50S is a big-bore JIS compact cylinder featuring a double-acting single rod and an external extend stop. A threaded M36x2.0 adjuster with a lock nut lets you set the extend end position on the machine, yielding a usable extend range of 0-50 mm from the 50 mm full stroke. The retract stroke remains completely unaffected.
Output force matches a standard ACQ because the piston area is unchanged by the stop. At 0.5 MPa it delivers 10053.1 N push and 9424.8 N pull, rising to 14074.3 N push at 0.7 MPa, with a maximum push of 2050 kgf at 1.0 MPa. The Ø40 mm rod uses an M24x3.0 female end, and the body integrates fixed NBR elastomer bumpers rather than adjustable air cushions.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 50 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 ACQJ160X50-50S Is Used
Press Tonnage Setup
Dial in the exact 0-50 mm extend position during stamping press changeovers to accommodate different die heights without machining new spacers.
Heavy Fixture Clamping
Adjust the clamping reach on the fly for oversized welding fixtures, ensuring optimal holding force before locking the nut.
Pallet Lift Positioning
Fine-tune the lift end-stop for varying pallet thicknesses in automated material handling lines, relying on the fixed bumper for end deceleration.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-50S the Right Cylinder?
For 0.5 MPa push requirements below 7696.9 N, step down to the Ø140 bore; if you need more than 10053.1 N, this Ø160 is your current ceiling in the compact line. A fixed-stroke ACQ suffices if your end position never varies. When ordering, confirm the 50 mm full stroke, 50 mm window, PT3/8 port, M24x3.0 female rod thread, and the -S magnet for electronic or reed switches.
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 ACQJ160X50-50S FAQ
It provides 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 50 mm full stroke has a 50 mm window, allowing a usable extend range of 0-50 mm.
The M36x2.0 threaded stop with lock nut limits only the extend length, leaving retract intact and keeping force identical to a standard ACQ. The cylinder uses fixed NBR bumpers, not air cushions, and will drift on air loss, so use an external rod lock for fail-safe holding.
