Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-75SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-75SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 200mm 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 ACQJ40X200-75SB
The ACQJ40X200-75SB is a double-acting JIS compact cylinder with a 200mm total stroke and a 75mm external adjustment window, letting you dial the extend end-position back to a 125mm minimum directly on the machine. Because the threaded stop limits travel without altering piston area, your output remains identical to a standard ACQ of the same bore. The retract distance stays completely unaffected.
This made-to-order long-stroke variant bypasses the 100mm standard maximum for this bore size. It features a 16mm piston rod, PT1/8 porting, a male M14x1.5 rod end, and an M12x1.25 adjuster thread. NBR elastomer bumpers handle end-of-stroke deceleration, and the included magnet supports reed or solid-state sensors.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 200 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 ACQJ40X200-75SB Is Used
Machining Fixture Stops
Dial in the exact extend position for varying raw material blanks on a CNC machining center without machining custom stop collars.
Package Sorter Diverter
Adjust the pusher extension length on the fly to handle different carton widths on a packaging conveyor during product changeover.
Assembly Press Stroke Setup
Fine-tune the pressing depth for trial runs on an automated assembly line, ensuring components seat perfectly before final lock-down.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-75SB the Right Cylinder?
When sizing this unit, the 40mm bore yields 628.3N push and 527.8N pull at 0.5MPa. Dropping to a 32mm bore reduces push to 402.1N, whereas a 50mm bore increases push to 981.8N. If your application never requires altering the extend length, a fixed-stroke ACQ cylinder provides a simpler setup. To order, confirm the 40mm bore, 200mm full stroke, 75mm window, the -S magnet, and -B male rod.
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 ACQJ40X200-75SB FAQ
It provides a push force of 628.3N and pull force of 527.8N at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The usable extend range is 125-200mm (200mm full stroke minus the 75mm window).
An external M12x1.25 threaded stop with a lock nut limits extend travel, leaving retract unaffected and keeping force identical to a standard ACQ. Fixed NBR bumpers decelerate the load near stroke ends; for fail-safe load holding on air loss, add an external rod lock or pilot-operated check valve.
