Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-50SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-50SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 100mm 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 ACQJ32X100-50SB
The AirTAC ACQJ32X100-50SB is a double-acting JIS compact cylinder with a 32 mm bore and a 100 mm full stroke. An external M12x1.25 threaded stop and lock nut limits the extend end position, providing a usable extend range of 50 to 100 mm. The retract stroke remains unaffected. Because the piston area is unchanged, force is identical to a standard ACQ of this bore.
This model includes a built-in piston magnet (-S) for use with reed or electronic solid-state switches, and a male M14x1.5 rod-end thread (-B) for direct load coupling. It features a PT1/8 port, a 16 mm piston rod, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.

| 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 ACQJ32X100-50SB Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC milling fixture without machining new spacer blocks.
Packaging Changeover
Rapidly reposition the product pusher end point when switching between different carton widths.
Assembly Press Trials
Safely test intermediate insertion depths on an electronics assembly press before finalizing the stroke.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-50SB the Right Cylinder?
When sizing this 32 mm bore actuator, note it delivers 402.1 N push and 301.6 N pull at 0.5 MPa. Stepping down to a 25 mm bore yields 245.4 N push, while stepping up to a 40 mm bore provides 628.3 N push. If your machine requires a fixed extend end position and never needs on-the-fly adjustment, a standard ACQ cylinder will suffice. To order, confirm the 32 mm bore, 100 mm full stroke, 50 mm adjustable window, magnet, and male rod thread.
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 ACQJ32X100-50SB FAQ
It provides a push force of 402.1 N and a pull force of 301.6 N at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 100 mm with a 50 mm adjustment window, resulting in a usable extend range of 50 to 100 mm.
An external M12x1.25 threaded screw with a lock nut mechanically limits the rod extension, shortening the stroke length without changing the piston area. The output force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration and does not hold the load on air loss; use an external rod lock for fail-safe holding.
