Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-50B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-50B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm 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 ACQJ32X150-50B
The AirTAC ACQJ32X150-50B is a double-acting JIS compact cylinder featuring a 150 mm stroke and a male-thread (M14x1.5) piston rod. An external threaded stop with a lock nut lets you limit the extend stroke, providing a usable extension range of 100 to 150 mm. The retract distance remains completely unaffected by this adjustment. Because the piston area stays constant, output force matches a standard ACQ exactly.
This long-stroke variant exceeds the 100 mm standard maximum for this bore size, making it a made-to-order option for applications needing extra reach. It features a 16 mm rod, PT1/8 porting, and an M12x1.25 adjuster thread. Fixed NBR elastomer bumpers absorb impact at both ends, while the body retains sensor grooves for adding external reed or solid-state switches, though this specific unit ships without a magnet.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-50B |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 150 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 ACQJ32X150-50B Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC fixture during setup, shortening the extend from 150 mm down to 100 mm to clear varying raw material heights without swapping cylinders.
Product Changeover Stops
Adjust the end-of-stroke stop position on a packaging line conveyor when transitioning between different carton sizes, using the lock nut to secure the new 120 mm extend endpoint.
Assembly Press Trials
Test multiple engagement depths on an automated assembly press, fine-tuning the rod extension by up to 50 mm to find the perfect pressing distance before finalizing the mechanical setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-50B the Right Cylinder?
When sizing this unit, note the 32 mm bore yields 402.1 N push and 301.6 N pull at 0.5 MPa. Stepping down to a 25 mm bore drops push to 245.4 N, while stepping up to a 40 mm bore increases push to 628.3 N. If your machine never requires end-position tuning, a fixed-stroke ACQ cylinder is simpler and sufficient. Confirm your ordering essentials: 32 mm bore, 150 mm full stroke, 50 mm window, male M14x1.5 rod (-B), and no magnet.
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 ACQJ32X150-50B FAQ
The 32 mm bore generates 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 150 mm, but the external adjuster allows you to shorten the extend stroke by up to 50 mm, giving a usable extension range of 100 to 150 mm.
The external M12x1.25 threaded stop with lock nut limits only how far the rod extends, meaning force remains identical to a standard ACQ because the piston area is unchanged. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions, so for high-speed loads you should slow the approach or add an external shock absorber.
