Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 30mm 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 ACQJ32X30-30SB
The ACQJ32X30-30SB is a double-acting JIS compact cylinder with a 32mm bore and a 30mm full stroke. It features an external M12x1.25 threaded stop with a lock nut that limits the extend end position, providing a usable extend range of 0-30mm without changing parts. The retract stroke remains unaffected, and the output force is identical to a standard ACQ of this size, delivering 402.1N push and 301.6N pull at 0.5 MPa.
Equipped with a male M14x1.5 rod end (-B) and a piston magnet (-S), this unit couples directly to loads and supports both reed and solid-state switches. It uses a PT1/8 port and relies on fixed NBR elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions. Operating pressure spans 0.15-1.0 MPa, with a speed range of 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 ACQJ32X30-30SB Is Used
Machining Fixture Stops
Dial in the extend position of clamping arms on machining fixtures to accommodate raw material variations without swapping cylinder hardware.
Product Changeover Guides
Quickly reposition product flow guides on packaging lines during format changes by twisting the external stopper to the new required length.
Assembly Press Probing
Establish trial end positions for pressing or probing tasks on automated assembly lines, ensuring parts seat correctly before finalizing the stroke.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30SB the Right Cylinder?
This 32mm bore provides 402.1N push at 0.5 MPa, sitting between the 25mm bore (245.4N push) and the 40mm bore (628.3N push). If your extend position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 32mm bore, 30mm full stroke, 30mm adjustment window, the -S magnet for sensing, and the -B male M14x1.5 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 ACQJ32X30-30SB FAQ
The usable extend range is 0-30mm (30mm full stroke minus the 30mm window). Force is identical to a standard ACQ: push is 402.1N and pull is 301.6N at 0.5 MPa, push is 562.9N at 0.7 MPa, and maximum push is 82 kgf at 1.0 MPa.
An external M12x1.25 threaded stop with a lock nut limits the extend length without altering piston area, so force remains unchanged. The cylinder uses fixed elastomer bumpers for deceleration. Note that a plain ACQ-type does not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
