Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-100B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-100B 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 ACQJ40X200-100B
The AirTAC ACQJ40X200-100B is a double-acting JIS compact cylinder with a 200mm full stroke and a male-thread piston rod end (M14x1.5). An external M12x1.25 threaded stop and lock nut restricts the extend travel, yielding a usable forward range of 100-200mm. The return stroke remains fixed at its original length. This unit is a long-stroke made-to-order variant, as 200mm exceeds the 100mm standard maximum for this 40mm bore.
Output force is identical to a standard ACQ of the same bore, delivering 628.3N push and 527.8N pull at 0.5MPa. The adjuster alters only the travel distance, not the piston area. Deceleration relies on a fixed NBR elastomer bumper at each end rather than an adjustable air cushion. While this specific SKU ships without a magnet, the body retains sensor grooves for adding reed or solid-state switches if needed later.

| 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 ACQJ40X200-100B Is Used
Machining Fixture Stops
Dial in the exact 100-200mm extend position for varying raw material lengths on a CNC lathe without machining custom stop blocks.
Carton Changeover
Rapidly adapt the pusher end-stop on a packaging line when switching between different box formats, using the external lock nut.
Press Trial Positions
Test multiple pressing depths on an assembly rig by turning the M12x1.25 adjuster, finding the optimal travel before finalizing the mechanical setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-100B the Right Cylinder?
When sizing this 40mm bore, dropping to a 32mm version lowers the 0.5MPa push force to 402.1N, while stepping up to a 50mm bore raises it to 981.8N. If your equipment never requires shifting the end position, a fixed-stroke ACQ40X200 will execute the same work more economically. To order correctly, confirm the 40mm bore, 200mm full travel, 100mm window, the male M14x1.5 rod thread, and the absence of a magnet. Remember that a plain ACQ will drift and lose its position if air pressure drops; utilize an external rod lock for fail-safe 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 ACQJ40X200-100B FAQ
This 40mm bore cylinder provides 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 100mm window allows the extend stroke to be fine-tuned within a 100-200mm usable range.
The external threaded stop limits how far the rod extends without changing the piston area, so force remains identical to a standard ACQ. Deceleration is handled by a fixed NBR bumper at each end, not an adjustable air cushion. The retract stroke is completely unaffected by the extend stop.
