Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-10B 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 ACQJ32X150-10B
The ACQJ32X150-10B is a double-acting JIS compact cylinder featuring a 32mm bore and a 150mm stroke. An external threaded stop with a lock nut limits the extend end position, allowing you to fine-tune the usable extend range from 140mm up to the full 150mm without changing parts. The retract stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore. This unit includes a male-thread piston rod end (M14x1.5) for direct load coupling, a PT1/8 port, and a fixed NBR elastomer bumper at each end.
This is a long-stroke, made-to-order variant, as the 150mm stroke exceeds the 100mm standard maximum for the 32mm bore. It operates at pressures from 0.15 to 1.0 MPa with speeds of 30-500 mm/s. The body retains magnetic-switch grooves, though this specific configuration ships without a magnet. Note that a plain compact cylinder does not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.

| 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 ACQJ32X150-10B Is Used
Fixture Setup Tuning
Dial in exact clamping depth on multi-part machining fixtures by adjusting the extend stop from 140 to 150mm without machining custom spacers.
Product Changeover Stops
Quickly reposition the end-of-stroke limit on packaging lines when switching between product sizes, using the external M12x1.25 adjuster nut.
Prototype End Positions
Safely test trial extend endpoints on new automated assembly equipment, finding the optimal reach before locking the rod in place.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-10B the Right Cylinder?
When sizing this model, verify that the 402.1N push force at 0.5 MPa is sufficient for your load. Stepping down to a 25mm bore yields 245.4N push, while stepping up to a 40mm bore provides 628.3N push. If your application requires a fixed 150mm extend position without on-machine adjustability, a standard ACQ32X150 cylinder would suffice. For ordering, confirm the 32mm bore, 150mm full stroke, 10mm adjuster window, the male rod thread (-B), and whether you need the -S magnet option for sensor integration.
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 ACQJ32X150-10B FAQ
The usable extend range is 140-150mm (150mm full stroke minus up to 10mm). Force is identical to a standard ACQ: push 402.1N and pull 301.6N at 0.5 MPa, push 562.9N at 0.7 MPa, with a maximum push of 82kgf at 1.0 MPa. The bore is 32mm, and the retract stroke is unaffected by the adjuster.
An external threaded stop (M12x1.25) with a lock nut mechanically limits how far the rod extends, shortening the stroke length only. It does not change the piston area, so output force remains unchanged. The cylinder uses a fixed NBR elastomer bumper at each end for deceleration, not an adjustable air cushion. For high energy loads, add an external shock absorber.
