Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-75SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-75SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 175mm 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 ACQJ160X175-75SB
The ACQJ160X175-75SB is a double-acting JIS compact cylinder featuring a big-bore 160 mm body and a 175 mm full stroke. An external threaded stop with a lock nut permits on-machine extend end-position tuning, yielding a usable extension range of 100 to 175 mm. The retract distance remains completely unaffected by this adjustment. Because the piston area stays constant, output force is identical to a standard ACQ of the same bore, giving 10053.1 N push and 9424.8 N pull at 0.5 MPa.
This variant includes the male piston rod end thread M36x1.5 for direct load coupling and a built-in magnet for position sensing. Fixed elastomer bumpers manage end-of-travel deceleration rather than adjustable air cushions. Operating pressure spans 0.15 to 1.0 MPa, and the PT3/8 port handles pneumatic supply.

| Bore size | Ø160 mm |
| Full stroke | 175 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 ACQJ160X175-75SB Is Used
Heavy Press Tonnage Calibration
Dial in the exact 100 to 175 mm extension on a large metalworking press to set precise stamping depth during material thickness changes.
Large Assembly Fixture Tuning
Alter the extend stop on a 160 mm bore clamping fixture to accommodate multi-model product changeovers without swapping mechanical spacers.
Wood Processing End Stops
Establish trial end positions for heavy board trimming or routing equipment, fine-tuning the stroke window on the machinery floor.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-75SB the Right Cylinder?
When sizing this big-bore unit, stepping down to a 140 mm bore yields 7696.9 N push at 0.5 MPa, while the 160 mm bore chosen here provides 10053.1 N. If your application requires fixed travel without end-position variance, a standard ACQ cylinder suffices and avoids the external adjuster. Confirm your ordering essentials: 160 mm bore, 175 mm full stroke, 75 mm adjustment window, male rod thread, and the piston magnet.
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 ACQJ160X175-75SB FAQ
It delivers 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 full stroke is 175 mm with a 75 mm adjustment window, allowing a usable extend range of 100 to 175 mm. The retract stroke remains fixed at 175 mm.
The external M36x2.0 threaded stop with a lock nut limits extension distance without altering piston area, meaning force is unchanged. Fixed NBR elastomer bumpers decelerate the rod near stroke ends rather than adjustable air cushions. A plain cylinder does not hold its load on air loss, so for fail-safe holding, install an external rod lock or pilot-operated check valve.
