Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 45mm 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 ACQJ32X45-10SB
The AirTAC ACQJ32X45-10SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut on the rod-end side. This mechanism lets you fine-tune the extend end position on the machine without swapping parts. The usable extend range spans 35-45mm (a 45mm full stroke shortened by up to a 10mm window), while the retract stroke remains completely unaffected.
Because the piston area stays constant, output force is identical to a standard ACQ of this bore, delivering 402.1N push and 301.6N pull at 0.5MPa. This SB configuration includes a male piston rod thread (M14x1.5) for direct load coupling and a built-in magnet (-S) for position sensing. The unit relies on a fixed NBR elastomer bumper at each end for deceleration and operates at speeds of 30-500mm/s.

| 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 (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 ACQJ32X45-10SB Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC fixture during part family changeovers without machining new spacer blocks.
Carton Sealing Stops
Adjust the pressing depth on a packaging line to accommodate different box heights or flap thicknesses rapidly.
Assembly Press Positions
Set precise trial end positions for pressing bearings or pins, allowing quick recovery if a prototype specification shifts.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10SB the Right Cylinder?
If you need slightly less thrust, the adjacent 25mm bore yields 245.4N push at 0.5MPa, whereas stepping up to a 40mm bore provides 628.3N push. A fixed-stroke ACQ32 is perfectly adequate if your extend endpoint never varies. When ordering this adjustable variant, confirm the 32mm bore, 45mm full stroke, 10mm adjustment window, plus the S magnet and B male rod options.
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 ACQJ32X45-10SB FAQ
It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The usable extend range is 35-45mm (45mm full stroke minus up to a 10mm window). The piston rod is 16mm with a male M14x1.5 thread, the port is PT1/8, and the external adjuster thread is M12x1.25.
No, the adjuster only limits how far the rod extends, so force remains identical to a standard ACQ. The unit uses fixed elastomer bumpers for deceleration rather than adjustable air cushions. The built-in -S magnet is compatible with both reed and electronic solid-state switches for position sensing.
