Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-75SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-75SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 100mm 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 ACQJ32X100-75SB
The AirTAC ACQJ32X100-75SB is a JIS double-acting compact cylinder featuring a 32mm bore and a 100mm full stroke. An external M12x1.25 threaded stop with a lock nut limits the extend travel, allowing you to fine-tune the usable forward range from 25mm up to 100mm directly on the machine. The return stroke remains fixed at its original length. Because the adjuster only restricts travel length and leaves piston area untouched, output force remains identical to a standard ACQ equivalent.
This model includes a built-in piston magnet for position sensing, compatible with either reed or electronic solid-state switches mounted in the body grooves. It features a male M14x1.5 rod end for direct load coupling, a PT1/8 port, and fixed NBR elastomer bumpers at both ends to absorb end-of-stroke impact. Operating pressure spans 0.15-1.0 MPa, with a maximum push capacity of 82 kgf at 1.0 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.

Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-75SB the Right Cylinder?
If your application needs less push force, the 25mm bore variant offers 245.4N push at 0.5 MPa, whereas stepping up to the 40mm bore yields 628.3N. Choose this 32mm bore when your setup requires approximately 402.1N of push force alongside a highly specific forward end-point. A fixed-stroke ACQ cylinder is sufficient if your end position never varies and requires no on-the-fly adjustments. Confirm your ordering essentials: 32mm bore, 100mm full stroke, 75mm adjustable window, -S magnet, and -B male rod thread.
Quick checklist

- ✓ 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 ACQJ32X100-75SB FAQ
It delivers 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The usable extend range is 25-100mm (a 100mm full stroke shortened by the 75mm window).
The external M12x1.25 adjuster changes only the stroke length, leaving force identical to a standard ACQ. Fixed elastomer bumpers absorb impact at the ends, and the -S magnet works with reed or solid-state switches.
