Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 15mm 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 ACQJ32X15-20SB
The ACQJ32X15-20SB is a double-acting JIS compact cylinder with a 32mm bore and a 15mm full stroke. An external threaded stop with a lock nut lets you fine-tune the extend end position on the machine, yielding a usable extend range of 0 to 15mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area stays the same, the output force equals that of a standard ACQ, delivering 402.1N push at 0.5MPa.
This unit includes a male M14x1.5 piston rod end for direct load coupling and a built-in magnet for position sensing. It features fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The piston rod measures 16mm in diameter, and the air connection port is PT1/8.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 15 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 ACQJ32X15-20SB Is Used
Product Changeover Stops
Dial in the extend position from 0 to 15mm on packaging lines when switching carton sizes, avoiding the need to machine new physical stop collars for each run.
Trial End Positions
Test clamping endpoints on a laboratory fixture by threading the external stop to find the exact contact pressure before locking the nut down permanently.
Setup-Varying Fixtures
Accommodate varying material thicknesses in a welding jig by simply turning the M12x1.25 adjuster screw to set the precise 0-15mm extend depth.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X15-20SB the Right Cylinder?
When sizing this actuator, consider the 32mm bore against neighbouring options. Stepping down to a 25mm bore yields 245.4N push at 0.5MPa, while moving up to a 40mm bore provides 628.3N push. If the exact 15mm extend position is fixed and never varies, a standard non-adjustable ACQ cylinder is sufficient. To order this adjustable version correctly, confirm the 32mm bore, 15mm full stroke, 20mm adjuster window, the -S magnet for switch readiness, 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 ACQJ32X15-20SB FAQ
The force is identical to a standard ACQ of this bore: 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 15mm with a 20mm adjustable window, giving a usable extend range of 0 to 15mm.
The external threaded stop with a lock nut limits only the extend stroke length, leaving the retract stroke unchanged. The cylinder uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. The included -S magnet supports both reed and electronic solid-state switches for position detection.
