Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-75
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-75 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 175mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-75
The AirTAC ACQJ40X175-75 is a double-acting JIS compact cylinder featuring a 175mm stroke and a 75mm external adjustment window, yielding a usable extend range of 100-175mm. An external M12x1.25 threaded stop with a lock nut lets you fine-tune the forward end position directly on your equipment without swapping parts. The retract stroke remains completely unaffected.
Because the piston area stays constant, output force matches a standard ACQ exactly: 628.3N push and 527.8N pull at 0.5MPa. This long-stroke made-to-order variant exceeds the 100mm standard maximum for this bore. It includes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and features sensor grooves, though this specific SKU ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 175 mm |
| Adjuster thread | M12×1.25 |
| Port size | PT1/8 |
| 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 | M8×1.25 (F) / M14×1.5 (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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-75 Is Used
CNC Tooling Setup
Dial in the exact extend distance for varying jig heights on a machining center without machining new spacer blocks.
Packaging Changeover
Rapidly adjust the pusher endpoint on a packaging line when switching between different carton depths or product sizes.
Prototype Positioning
Establish optimal trial end positions for new automated assembly stations by tweaking the external stop nut on the fly.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-75 the Right Cylinder?
When sizing this actuator, consider the neighbouring bores: a 32mm bore provides 402.1N push at 0.5MPa, while a 50mm bore yields 981.8N. If your extend endpoint never varies, a fixed-stroke ACQ cylinder is simpler and more cost-effective. For this adjustable unit, confirm your ordering essentials: 40mm bore, 175mm full stroke, 75mm window, female M8x1.25 rod end, and PT1/8 porting. Remember that a standard cylinder drifts if air pressure is lost; utilize an external rod lock for fail-safe load 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 ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-75 FAQ
It delivers 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The 175mm total stroke includes a 75mm adjustment window, providing a usable extend range of 100-175mm.
The M12x1.25 threaded rod-end stop mechanically limits the forward extension distance without altering piston area, so force remains identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers rather than adjustable air cushions, so for high-speed loads you should add an external shock absorber.
