Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-30SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-30SB 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 ACQJ40X150-30SB
The ACQJ40X150-30SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend range from 120 mm up to the full 150 mm on the machine without changing parts, while the retract stroke remains unaffected. This 150 mm unit is a made-to-order long-stroke variant, exceeding the 100 mm standard maximum for this 40 mm bore.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same size, yielding 628.3 N push and 527.8 N pull at 0.5 MPa. The unit includes a male M14x1.5 rod-end thread for direct load coupling, a PT1/8 port, and fixed NBR elastomer bumpers at both ends. The built-in piston magnet (-S) supports both reed and electronic solid-state switches.

| 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 |

| 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 ACQJ40X150-30SB Is Used
Machining Fixture Stops
Dial in the exact 120-150 mm extend position during CNC setup to accommodate varying raw casting lengths without machining custom spacer blocks.
Packaging Format Changeover
Rapidly adjust the extend endpoint on a carton sealing head to handle different box heights on the fly, minimizing production line downtime.
Assembly Press Trial
Safely test intermediate end positions when seating bearings on a new assembly line, preventing over-travel by limiting the extend stroke.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-30SB the Right Cylinder?
When sizing this actuator, consider the neighbouring bores: a 32 mm bore provides 402.1 N push at 0.5 MPa, while a 50 mm bore offers 981.8 N. This 40 mm model delivers 628.3 N push and 879.6 N at 0.7 MPa, with a maximum push capacity of 128 kgf at 1.0 MPa. If your application never requires end-position tuning, a fixed-stroke ACQ cylinder will suffice. To order, confirm the 40 mm bore, 150 mm full stroke, 30 mm adjustable window, the -S magnet, and the -B male rod thread. Note that a plain compact cylinder will drift and lose its load on air loss; for fail-safe holding, add an external rod lock or pilot-operated check valve.
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 ACQJ40X150-30SB FAQ
The usable extend range is 120-150 mm (a 150 mm full stroke shortened by up to a 30 mm window). Force is identical to a standard ACQ: 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The retract stroke is unaffected.
An external M12x1.25 threaded stop with a lock nut mechanically limits the extend length, changing stroke length only without altering piston area or force. The cylinder uses fixed NBR elastomer bumpers at each end rather than adjustable air cushions. The included -S piston magnet works with both reed and electronic solid-state switches.
