Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-30B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-30B 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 ACQJ32X150-30B
The AirTAC ACQJ32X150-30B is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut on the extend side. This mechanism allows you to fine-tune the extend end position directly on your equipment. With a full stroke of 150 mm and a 30 mm adjustment window, the usable extend range spans 120 to 150 mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. This specific unit is a long-stroke variant exceeding the 100 mm standard maximum for this bore size. It includes a male-thread piston rod end (M14x1.5) for direct load coupling, PT1/8 porting, and fixed elastomer bumpers at both ends. Note that this model ships without a magnet, though the body retains sensor grooves.

| 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 ACQJ32X150-30B Is Used
Product Changeover Stops
Adjust the extend stop within the 120-150 mm range during packaging line format changes to set new product pusher positions without machining new parts.
Trial End Positions
Dial in the exact clamping depth on a CNC fixture during first-article inspection, relying on the 301.6 N pull force to hold the workpiece securely.
Setup-Varying Fixtures
Modify the extend reach on automated assembly presses for different component heights, using the M14x1.5 male rod thread to swap tooling quickly.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-30B the Right Cylinder?
Choosing this bore provides a middle-ground capacity; stepping down to a 25 mm bore drops the 0.5 MPa push force to 245.4 N, while moving up to a 40 mm bore increases it to 628.3 N. If your application never requires end-position tuning, a fixed-stroke ACQ cylinder would suffice and simplify setup. When ordering this long-stroke unit, confirm the 32 mm bore, 150 mm full stroke, 30 mm window, the male rod thread option (-B), and that no magnet is required.
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 ACQJ32X150-30B FAQ
The usable extend range is 120-150 mm (150 mm full stroke minus a 30 mm window). The force is identical to a standard ACQ: push is 402.1 N and pull is 301.6 N at 0.5 MPa, push is 562.9 N at 0.7 MPa, and maximum push is 82 kgf at 1.0 MPa. The external adjuster thread is M12x1.25.
An external threaded stop with a lock nut limits the extend stroke length only; the retract stroke and force remain unchanged. The cylinder uses fixed elastomer bumpers for end-of-stroke deceleration, not adjustable air cushions. A plain cylinder does not hold its load if air is lost, so an external rod lock or pilot-operated check valve is recommended for fail-safe holding.
