Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-50SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-50SB 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 ACQJ32X150-50SB
The AirTAC ACQJ32X150-50SB is a double-acting JIS compact cylinder with a 32mm bore and a 150mm full stroke. Because 150mm exceeds the standard 100mm maximum for this bore, this is a long-stroke made-to-order variant. An external M12x1.25 threaded stop and lock nut restricts how far the rod extends, yielding a usable extend range of 100-150mm. The retract distance remains completely unaffected. A -B male M14x1.5 rod end couples directly to your load, while the PT1/8 port manages pneumatic supply.
Output force matches a standard ACQ of identical size: 402.1N push and 301.6N pull at 0.5MPa, reaching 562.9N push at 0.7MPa and a maximum 82kgf at 1.0MPa. The adjuster alters stroke length only, never piston area. NBR elastomer bumpers decelerate the motion at each end, and the -S magnet supports reed or solid-state sensors.

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 ACQJ32X150-50SB Is Used
Machining Fixture Stops
Dial in exact clamp endpoints on multi-part CNC fixtures without machining new spacer blocks.
Product Changeover Guides
Rapidly reposition diverter arms on packaging lines during format size transitions.
Prototype Press Testing
Safely test trial extend positions on assembly presses before finalizing hard stops.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-50SB the Right Cylinder?
If you need less force, the next smaller Ø25 bore yields 245.4N push @0.5MPa; if you need more, step up to the Ø40 bore for 628.3N push @0.5MPa. If your extend endpoint never varies, a fixed-stroke ACQ32X150 suffices. For this adjustable unit, confirm the 32mm bore, 150mm full stroke, 50mm window, -S magnet, and -B male rod thread when ordering.
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 ACQJ32X150-50SB FAQ
It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum 82kgf push at 1.0MPa. The full stroke is 150mm, but the external stop provides a 50mm adjustment window, allowing a usable extend range of 100-150mm.
The external M12x1.25 threaded stop with lock nut limits extension length only, leaving retract untouched. Because piston area is unchanged, force remains identical to a standard ACQ. NBR bumpers decelerate the stroke at both ends. Note that a plain compact cylinder will drift on air loss; for fail-safe holding, add an external rod lock.
