Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 175mm 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 ACQJ32X175-50SB
The ACQJ32X175-50SB is a double-acting JIS compact cylinder featuring a 175mm stroke and an external extend stop. A threaded M12x1.25 adjuster with a lock nut lets you fine-tune the extend end position on the machine, providing a usable forward range of 125mm up to the full 175mm. The retract distance remains completely unaffected by this mechanism.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore, yielding 402.1N push and 301.6N pull at 0.5 MPa. This specific configuration is a made-to-order long-stroke variant, exceeding the 100mm standard maximum for a 32mm bore. It includes a male M14x1.5 piston rod end for direct load coupling, a built-in piston magnet for position sensing, and fixed NBR elastomer bumpers at both ends.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 175 mm |
| 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ32X175-50SB Is Used
Machining Fixture Positioning
Dial in the exact clamping reach on a CNC fixture during setup, adjusting the extend stroke from 125 to 175mm without swapping out the entire actuator.
Packaging Line Changeover
Accommodate varying carton sizes on a packaging conveyor by turning the external stop to set new product-contact points rapidly.
Lab Automation End Stops
Establish trial end positions for a 32mm bore sample handling probe, relying on the 82 kgf max push to seat components securely.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50SB the Right Cylinder?
When sizing this actuator, consider the adjacent bores: a 25mm bore provides 245.4N push, while a 40mm bore yields 628.3N push at 0.5 MPa. If your extend position never varies, a fixed-stroke ACQ cylinder is simpler and more compact. For this model, confirm the 32mm bore, 175mm full stroke, 50mm adjuster window, and the S magnet with B male rod options. Note that at high speeds, the fixed elastomer bumper may require an external shock absorber. Additionally, a plain compact cylinder will drift on air loss, so utilize an external rod lock for fail-safe holding.

- ✓ 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 ACQJ32X175-50SB FAQ
This 32mm bore cylinder 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 full stroke is 175mm, but the external adjuster allows you to shorten the extend stroke by up to 50mm, giving a usable extend range of 125-175mm.
An external M12x1.25 threaded stop with a lock nut mechanically limits how far the rod extends, changing only the stroke length and not the piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected. The fixed NBR bumpers decelerate the load at both ends, and the included magnet works with either reed or electronic solid-state switches.
