Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-50
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-50 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 150mm 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 ACQJ40X150-50
The ACQJ40X150-50 is a double-acting single-rod JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 100mm up to the full 150mm directly on your machinery without swapping parts. The retract stroke remains completely unaffected by this adjustment. Because the piston area stays constant, the output force is identical to a standard ACQ of the same bore.
This specific configuration is a long-stroke variant, as the 150mm stroke exceeds the 100mm standard maximum for a 40mm bore, making it a made-to-order item. It delivers 628.3N of push force and 527.8N of pull force at 0.5MPa, operating with a 16mm piston rod and PT1/8 port. The unit relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion, and while the body features sensor grooves, this particular model ships without a magnet.

| 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 ACQJ40X150-50 Is Used
Machining Fixture Stops
Dial in the exact extend position from 100 to 150mm on a CNC machining fixture to accommodate different raw material lengths without fabricating custom stop blocks.
Packaging Changeover
Adjust the extend stroke on a carton sealing head during product format changeovers, allowing quick transitions between varying box sizes on the same line.
Press Trial Positions
Set trial end positions on a small pneumatic press during prototype development, testing multiple extend depths safely before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-50 the Right Cylinder?
When sizing this unit, consider the 32mm bore variant which yields 402.1N push at 0.5MPa, or the larger 50mm bore providing 981.8N push if your application requires greater thrust. If your end position never varies, a fixed-stroke ACQ cylinder is sufficient and avoids the adjuster overhang. For this adjustable model, confirm the 40mm bore, 150mm full stroke, 50mm window, female M8x1.25 rod thread, and note the absence of the S magnet option. Since 150mm exceeds the 100mm standard max, expect a made-to-order lead time.
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 ACQJ40X150-50 FAQ
This 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 full stroke is 150mm with a 50mm window, allowing a usable extend range of 100-150mm. The retract stroke is unaffected. Note that 150mm exceeds the 100mm standard max for this bore, making it a long-stroke made-to-order variant.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke, allowing on-machine tuning without changing parts. The adjuster changes stroke length only, so force remains identical to a standard ACQ. The cylinder uses a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. This model ships without a sensor magnet, though the body retains switch grooves.
