Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75SB 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 ACQJ32X150-75SB
The AirTAC ACQJ32X150-75SB is a double-acting JIS compact cylinder with a 150 mm stroke that exceeds the 100 mm standard maximum for a 32 mm bore, placing it in the long-stroke made-to-order category. It features an external M12x1.25 threaded stop with a lock nut on the extend side, allowing you to fine-tune the end position directly on the machine. The usable extend range spans 75 to 150 mm, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, force output is identical to a standard ACQ of this bore: 402.1 N push and 301.6 N pull at 0.5 MPa. This SB configuration includes a built-in piston magnet for use with reed or solid-state switches, and a male M14x1.5 rod-end thread that couples directly to the load. Deceleration is handled by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions.

| 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 ACQJ32X150-75SB Is Used
Machining Fixture Stops
Dial in the extend stop on a CNC machining fixture to accommodate raw part tolerances without fabricating new hard stops.
Product Changeover
Rapidly adjust the extend reach on a packaging line during format changes, shifting the end position within the 75-150 mm window.
Prototype Positioning
Test various extend end positions on a lab automation rig, locking the M12x1.25 adjuster nut once the optimal travel is found.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-75SB the Right Cylinder?
Selecting this 32 mm bore yields 402.1 N push at 0.5 MPa; dropping to a 25 mm bore reduces push to 245.4 N, while stepping up to a 40 mm bore increases it to 628.3 N. If the exact extend position never varies, a fixed-stroke ACQ cylinder is simpler and more economical. When ordering, confirm the 150 mm full stroke, the 75 mm adjustable window, the S magnet, and the B male rod thread.
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 ACQJ32X150-75SB FAQ
The usable extend range is 75-150 mm (a 150 mm full stroke minus up to 75 mm via the external stop). Force is identical to a standard ACQ: 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.
An external M12x1.25 threaded stop with a lock nut limits the extend distance without altering the piston area, so force remains unchanged. The cylinder uses fixed NBR elastomer bumpers for deceleration. It does not hold the load on air loss; for fail-safe holding, use an external rod lock.
