Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10 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 ACQJ40X200-10
The AirTAC ACQJ40X200-10 is a double-acting JIS compact cylinder with an external adjuster for the extend stroke. It is a long-stroke variant exceeding the 100mm standard maximum for this bore. The external M12x1.25 threaded stop with lock nut lets you dial the usable extend range from 190mm up to the full 200mm without changing parts. The retract stroke remains completely unaffected.
Because the piston area is unchanged, output force equals a standard ACQ of this bore. You get 628.3N push and 527.8N pull at 0.5MPa. The unit features a fixed elastomer bumper at each end for end-of-stroke deceleration and operates at speeds of 30-500mm/s. Note that this specific configuration ships without a magnet, though the body retains sensor grooves for adding switches externally.

| 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 |

| 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 ACQJ40X200-10 Is Used
Fixture Position Tuning
Dial in the exact 190-200mm extend position on machining fixtures during setup, avoiding the need to fabricate custom spacer rings.
Product Changeover Stops
Adapt assembly line end-stops rapidly when switching between product variants by turning the external adjuster instead of replacing cylinders.
Trial End Positions
Test prototype end positions on packaging equipment safely, fine-tuning the stroke length on the machine until the optimal motion is found.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10 the Right Cylinder?
For sizing context, stepping down to a 32mm bore drops the 0.5MPa push force to 402.1N, while a 50mm bore increases it to 981.8N. If your machine never requires end-position adjustments, a fixed-stroke ACQ cylinder will suffice. When ordering this unit, confirm the 40mm bore, 200mm full stroke, 10mm window, female M8x1.25 rod thread, and PT1/8 port. Remember that a plain compact cylinder does not hold its load on air loss; for a fail-safe hold, specify an external rod lock or pilot-operated check valve.
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 ACQJ40X200-10 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 full stroke is 200mm with a 10mm window, giving a usable extend range of 190-200mm. The retract stroke is unaffected.
The external M12x1.25 threaded stop limits how far the rod extends, shortening the stroke without altering the piston area, so force remains identical to a standard ACQ. Deceleration is handled by a fixed elastomer bumper, not an adjustable air cushion.
