Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-50S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 200mm 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 ACQJ32X200-50S
The AirTAC ACQJ32X200-50S is a double-acting JIS compact cylinder built for applications requiring a long 200mm stroke with on-machine extend tuning. An external M12x1.25 threaded stop and lock nut lets you shorten the forward stroke by up to 50mm, yielding a usable extend range of 150 to 200mm. The retract distance remains completely unaffected by this adjustment.
Because the piston area is unchanged, output force matches a standard ACQ exactly, delivering 402.1N push and 301.6N pull at 0.5MPa. This 32mm bore variant features a PT1/8 port, a 16mm piston rod, and a built-in magnet (-S) compatible with reed or solid-state switches. It includes fixed NBR elastomer bumpers rather than adjustable air cushions. Note that the 200mm length exceeds the standard 100mm maximum for this bore, making it a made-to-order long-stroke unit.

| 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 |

| 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 ACQJ32X200-50S Is Used
Variable Length Gauging
Dial in the exact extend position from 150 to 200mm on a part inspection station without machining new hard stops.
Product Changeover Stops
Rapidly reposition the 32mm bore actuator's end point on a packaging line when switching between different carton depths.
Prototype Tooling Setup
Safely test forward reach limits on a new CNC fixture by starting at 150mm and extending the stroke in small increments.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-50S the Right Cylinder?
Selecting this actuator means choosing a 32mm bore that pushes 402.1N at 0.5MPa; sizing down to a 25mm bore drops push to 245.4N, while stepping up to 40mm increases it to 628.3N. If your equipment never requires end-position tweaking, a fixed-stroke ACQ cylinder provides the exact same power in a more compact footprint. When ordering this adjustable variant, confirm the 200mm full stroke, 50mm window, S magnet option, and female M8x1.25 rod-end thread. For high kinetic energy at 200mm, specify an external shock absorber since the fixed bumper only decelerates near the end points.
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 ACQJ32X200-50S FAQ
It 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 200mm with a 50mm adjustable window, giving a usable extend range of 150-200mm. It is a long-stroke made-to-order unit exceeding the 100mm standard max for a 32mm bore.
No, the external M12x1.25 stop alters only the extend length, leaving piston area and force identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers at both ends for basic end-of-stroke deceleration instead of adjustable air cushions. The built-in -S magnet works with reed or solid-state switches.
