Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-50B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-50B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 50mm 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 ACQJ32X50-50B
The AirTAC ACQJ32X50-50B is a double-acting JIS compact cylinder with a 50mm stroke and a 32mm bore. An external M12x1.25 threaded stop and lock nut limits the extend end position, providing a usable extend range of 0-50mm without changing parts. The retract stroke remains unaffected. Force is identical to a standard ACQ of this bore, delivering 402.1N push and 301.6N pull at 0.5MPa.
This unit includes the -B male M14x1.5 rod-end thread for direct load coupling and uses a PT1/8 port. It features a fixed NBR elastomer bumper at each end for end-of-stroke deceleration. The body retains magnetic-switch grooves, but this specific configuration ships without a sensor magnet.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-50B Technical Specifications
| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-50B |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 50 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 ACQJ32X50-50B Is Used
Machine Changeovers
Dial in the extend stop from 0 to 50mm during product changeovers on a machining fixture to accommodate different part depths without swapping hardware.
Assembly Press Tuning
Set precise trial end positions for pressing or seating components on an assembly line, using the external stop to find the optimal contact depth.
Variable Format Stops
Adjust the extend stroke on packaging equipment to position pusher plates for varying carton sizes, relying on the fixed bumper for consistent retraction.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-50B the Right Cylinder?
Selecting this 32mm bore provides a push force of 402.1N at 0.5MPa. If your application requires less force, stepping down to a 25mm bore yields 245.4N push, while moving up to a 40mm bore provides 628.3N push. A fixed-stroke ACQ cylinder is sufficient if your extend end position never requires on-machine tuning. Confirm your ordering essentials: 32mm bore, 50mm full stroke, 50mm window, male M14x1.5 rod thread, and no magnet.
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 ACQJ32X50-50B FAQ
The usable extend range is 0-50mm. Force is identical to a standard ACQ: push is 402.1N and pull is 301.6N at 0.5MPa, push is 562.9N at 0.7MPa, and max push is 82kgf at 1.0MPa. The adjuster changes stroke length only, not piston area.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke, while the retract stroke is unaffected. This model has a -B male M14x1.5 rod thread and no -S sensor magnet, though the body retains grooves for adding reed or solid-state switches.
