Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-30SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-30SB 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 ACQJ32X150-30SB
The ACQJ32X150-30SB is a double-acting, single-rod JIS compact cylinder built for precise extend-stroke control. It features an external M12x1.25 threaded stop with a lock nut on the rod-end side, allowing you to fine-tune the extend position directly on the machine. You can shorten the extend travel by up to 30 mm, yielding a usable extend range of 120 to 150 mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, the output force is identical to a standard ACQ of the same bore: 402.1 N push and 301.6 N pull at 0.5 MPa. This specific configuration includes a long 150 mm stroke, which exceeds the 100 mm standard maximum for a 32 mm bore, making it a made-to-order long-stroke variant. It comes equipped with a male M14x1.5 rod-end thread for direct load coupling, a built-in piston magnet for position sensing, and fixed NBR elastomer bumpers at both ends for end-of-travel deceleration.

| 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 ACQJ32X150-30SB Is Used
Machining Fixture Clamps
Dial in the exact clamping extension on a machining fixture during part setup or tooling changes without disassembling the cylinder or swapping internal spacers.
Carton Forming Stops
Adjust the pusher end position on the fly to accommodate different packaging carton sizes or product depths on a single packaging line.
Assembly Press Trial
Test and set trial end positions for pressing sub-components on an assembly rig, tweaking the 120-150 mm extend range until the perfect insertion depth is found.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-30SB the Right Cylinder?
When sizing this unit, consider the neighbouring bores: a 25 mm bore yields 245.4 N push at 0.5 MPa, while a 40 mm bore provides 628.3 N. This 32 mm model is the correct middle ground for applications needing 402.1 N of push force. If your end position never varies, a fixed-stroke standard ACQ cylinder will suffice and avoids the adjuster. However, if you need on-the-fly stroke changes, confirm your ordering essentials: 32 mm bore, 150 mm full stroke, 30 mm window, the S magnet, and the B male rod thread. Note that at high speeds, the fixed bumper may require an external shock absorber, and a plain ACQ will not hold a load on air loss—consider an external rod lock for fail-safe holding.
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 ACQJ32X150-30SB FAQ
This long-stroke cylinder has a usable extend range of 120 to 150 mm (150 mm full stroke minus the 30 mm adjustable window). The force is identical to a standard ACQ of the same bore: 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. The retract stroke is unaffected by the adjuster.
The external M12x1.25 threaded stop with lock nut limits only the extend stroke; it does not change the piston area or reduce the output force. The cylinder uses fixed NBR elastomer bumpers at each end for deceleration rather than adjustable air cushions. For load holding, a plain ACQ-type cylinder will drift on air loss or valve centering, so an external rod lock or pilot-operated check valve is recommended for fail-safe operation.
