Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X250-100B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X250-100B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 250mm 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 ACQJ32X250-100B
The ACQJ32X250-100B is a double-acting JIS compact cylinder featuring a 250mm stroke and a male M14x1.5 rod end. An external M12x1.25 threaded stop with a lock nut limits the extend end position, yielding a usable forward range of 150 to 250mm. The retract stroke remains unaffected by this adjustment. Because the piston area is unchanged, output force matches a standard ACQ exactly.
This made-to-order variant extends past the standard 100mm maximum for a 32mm bore, reaching 250mm. It delivers 402.1N push and 301.6N pull at 0.5MPa, with fixed NBR elastomer bumpers at each end. The body includes magnetic-switch grooves, though this specific configuration ships without a magnet.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X250-100B |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 250 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 ACQJ32X250-100B Is Used
Multi-Depth Clamping
Dial in varying material thicknesses on a machining fixture by turning the extend stop, achieving precise clamping without swapping out the entire actuator.
Product Changeover Diverters
Adjust the stroke length on a packaging line diverter to accommodate different carton sizes on the fly, minimizing downtime between production runs.
Prototype Stroke Setup
Safely test different end positions on an assembly press during the R&D phase, locking the nut once the optimal travel distance is found.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X250-100B the Right Cylinder?
When sizing this unit, dropping to a 25mm bore lowers push force to 245.4N at 0.5MPa, while stepping up to a 40mm bore raises it to 628.3N. If your machine never requires end-position tuning, a fixed-stroke ACQ cylinder provides identical holding power in a shorter footprint. To order this adjustable version, confirm the 32mm bore, 250mm length, 100mm window, male rod thread, and operating pressure up to 1.0MPa.
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 ACQJ32X250-100B FAQ
This 32mm bore cylinder provides 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 full stroke is 250mm, and with the 100mm adjustment window, the usable extend range is 150 to 250mm.
The external M12x1.25 threaded stop mechanically limits the forward travel, leaving the retract stroke unaffected and keeping the output force identical to a standard ACQ. Deceleration relies on fixed elastomer bumpers, not adjustable air cushions. Note that a plain compact cylinder will drift if air pressure is lost, so an external rod lock is required for fail-safe load holding.
