Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-10B 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 ACQJ32X50-10B
The AirTAC ACQJ32X50-10B is a double-acting JIS compact cylinder with a 32mm bore and a 50mm full stroke. An external M12x1.25 threaded stop and lock nut limits the rod extension, yielding a usable extend range of 40-50mm. You can fine-tune the forward end position directly on the machine without swapping parts, while the retract stroke remains completely unaffected.
Because the adjuster only alters travel length and not the piston area, output force stays identical to a standard ACQ of this size. The unit delivers 402.1N of push force and 301.6N of pull force at 0.5MPa. It features a male M14x1.5 rod-end thread for direct load coupling, fixed NBR elastomer bumpers at both ends, and operates at speeds from 30 to 500mm/s.

| 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 ACQJ32X50-10B Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC mill fixture to accommodate raw material thickness variations without machining new stop blocks.
Packaging Machine Changeover
Rapidly adjust the product push-off end position on a cartoning line during format size changes to minimize line downtime.
Assembly Press Positioning
Set precise trial insertion depths for bearing presses on an automated assembly line, allowing safe and gradual depth verification.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-10B the Right Cylinder?
When sizing this 32mm bore actuator, stepping down to a 25mm version drops the 0.5MPa push force to 245.4N, whereas moving up to a 40mm bore raises it to 628.3N. If your equipment never requires end-position tweaks, a fixed-stroke ACQ cylinder provides the exact same power in a simpler package. To order this adjustable variant correctly, confirm the 32mm bore, 50mm full stroke, 10mm adjuster window, male rod thread, and whether you need the S magnet option for sensor tracking.
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 ACQJ32X50-10B FAQ
This 32mm bore cylinder generates 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, with a maximum push of 82kgf at 1.0MPa. The full stroke is 50mm, but the external adjuster allows you to shorten the extend travel by up to 10mm, creating a usable extend range of 40-50mm.
No, the adjuster only limits the rod extension length, so the output force remains identical to a standard ACQ. Deceleration is provided by fixed NBR elastomer bumpers at both ends rather than an adjustable air cushion; for high-energy impacts, add an external shock absorber. Note that this model lacks a sensor magnet.
