Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 75mm 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 ACQJ32X75-10S
The AirTAC ACQJ32X75-10S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut to limit the extend end position. With a 75 mm full stroke and a 10 mm adjustment window, you can fine-tune the usable extend range from 65 mm up to 75 mm directly on the machine. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, output force is identical to a standard ACQ of the same bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The 32 mm bore uses a PT1/8 port and a 16 mm piston rod. It includes a built-in magnet for position sensing and relies on fixed NBR elastomer bumpers at both ends for end-of-stroke 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 ACQJ32X75-10S Is Used
Machining Fixture Stops
Dial in the exact 65 to 75 mm extend position on a CNC machining fixture to accommodate raw part tolerances without machining new stop blocks.
Packaging Changeover
Rapidly adjust the extend endpoint during packaging line format changeovers to push varying carton widths without swapping out the cylinder.
Assembly Press Trials
Set trial end positions on an automated assembly press to test component seating depths before locking down the final mechanical stop.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-10S the Right Cylinder?
This 32 mm bore provides 402.1 N push at 0.5 MPa; stepping down to a 25 mm bore drops force to 245.4 N, while a 40 mm bore raises it to 628.3 N. If your application never requires end-position changes, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 32 mm bore, 75 mm full stroke, 10 mm window, the -S magnet, and the default female M8x1.25 rod-end 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 ACQJ32X75-10S FAQ
It delivers 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 10 mm adjustment window allows a usable extend range of 65-75 mm.
An M12x1.25 threaded adjuster with a lock nut mechanically limits the extend length, meaning force remains identical to a standard ACQ since piston area is unchanged. The cylinder uses fixed NBR elastomer bumpers for deceleration, and the included -S magnet works with both reed and solid-state electronic switches.
