Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-75S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-75S 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 ACQJ160X100-75S
The ACQJ160X100-75S is a big-bore JIS compact pneumatic cylinder featuring a double-acting single rod and an external extend stop. An M36x2.0 threaded adjuster paired with a lock nut lets you dial the forward end position down by 75 mm. This creates a usable extend range of 25 to 100 mm, while the retract stroke remains completely unaffected.
Output force stays identical to a standard ACQ of this size because the piston area is unchanged. At 0.5 MPa you get 10053.1 N push and 9424.8 N pull, peaking at 14074.3 N push at 0.7 MPa. The Ø40 mm rod uses an M24x3.0 female end, and fixed NBR elastomer bumpers absorb impact at both extremes rather than relying on adjustable air cushions.

| 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 |

| 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 ACQJ160X100-75S Is Used
Heavy Press Tonnage Setup
Dial in the exact 25 to 100 mm pressing distance on a large stamping press without machining new spacers for different material thicknesses.
Large Fixture Changeover
Adapt automated welding clamps for new heavy-truck chassis parts by turning the external M36x2.0 stop to shift the extend endpoint instantly.
Palletizer End Stops
Vary the lower push-off position on a robotic palletizing head to handle different pallet heights while relying on the fixed bumper for end deceleration.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-75S the Right Cylinder?
If you need slightly less thrust, the neighboring Ø140 bore yields 7696.9 N push at 0.5 MPa, whereas stepping up is unnecessary here as Ø160 is the largest big-bore option delivering 10053.1 N push. Choose a fixed-stroke ACQ if your end position never varies. When ordering this adjustable variant, confirm the 100 mm total stroke, the 75 mm window, the built-in S magnet, and the female rod 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 ACQJ160X100-75S FAQ
The usable extend range is 25-100 mm (100 mm full stroke minus the 75 mm window). It delivers 10053.1 N push and 9424.8 N pull at 0.5 MPa, 14074.3 N push at 0.7 MPa, with a maximum push of 2050 kgf at 1.0 MPa.
The external M36x2.0 threaded stop with lock nut physically limits how far the rod extends, shortening the forward stroke only. The retract stroke is unaffected, and because the piston area remains the same, output force is identical to a standard ACQ. The cylinder uses fixed NBR bumpers, not adjustable air cushions.
