Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-40SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X100-40SB
The AirTAC ACQJ40X100-40SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 60 mm up to the full 100 mm stroke directly on the machine without changing parts, while the retract stroke remains completely unaffected. This bore 40 unit includes a male M14x1.5 rod-end thread that couples directly to your load and a built-in piston magnet for position sensing.
Because the piston area is unchanged, the force output is identical to a standard ACQ of the same bore, delivering 628.3 N push and 527.8 N pull at 0.5 MPa. The cylinder body uses a compact C-clip and riveted construction with fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration. It operates at pressures from 0.15 to 1.0 MPa and supports speeds between 30 and 500 mm/s.

| 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 |

| 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X100-40SB Is Used
Product Changeover Stops
Adjust the extend position within the 60-100 mm window during packaging format changes to accommodate different carton widths without swapping hardware.
Assembly Fixture Tuning
Dial in the exact clamping end point on machining fixtures during initial setup or when introducing slight part variations.
Trial End Positions
Test different extend lengths on automated handling lines to find the optimal transfer distance before locking down the stop nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-40SB the Right Cylinder?
If you need less push force, the bore 32 version provides 402.1 N at 0.5 MPa, while stepping up to the bore 50 model yields 981.8 N. A fixed-stroke ACQ cylinder is sufficient if your end position never varies and requires no on-machine adjustment. To order this adjustable unit correctly, confirm the 40 mm bore, 100 mm full stroke, 40 mm adjustable window, the -S magnet for electronic or reed switches, and the -B 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 ACQJ40X100-40SB FAQ
It delivers 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The usable extend range is 60 to 100 mm, created by shortening the 100 mm full stroke by up to the 40 mm window.
The external M12x1.25 threaded stop with a lock nut limits the extend stroke length only, meaning force is identical to a standard ACQ and the fixed elastomer bumper still decelerates the load near stroke end. This plain cylinder does not hold its load on air loss, so use an external rod lock or pilot-operated check valve for fail-safe holding.
