Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-100B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-100B 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 ACQJ32X100-100B
The AirTAC ACQJ32X100-100B is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend range from 0 mm up to the full 100 mm directly on the machine. The retract stroke remains completely unaffected by this adjustment. This unit includes a male M14x1.5 piston rod end for direct load coupling and utilizes a PT1/8 port.
Because the piston area stays the same, the output force is identical to a standard ACQ of this bore, yielding 402.1 N push and 301.6 N pull at 0.5 MPa. The cylinder body incorporates sensor grooves for reed or solid-state switches, though this specific configuration ships without a magnet. Deceleration is handled by a fixed NBR elastomer bumper at each end rather than an adjustable air cushion.

| 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 ACQJ32X100-100B Is Used
CNC Fixture Depth Tuning
Dial in the exact clamping depth on a CNC machining fixture during setup, allowing rapid accommodation of varying part heights without swapping out cylinder hardware.
Packaging Line Changeover
Modify the extend stroke on a packaging conveyor diverter to handle different carton sizes, using the external stop to set new end positions quickly.
Assembly Press Prototyping
Establish trial end positions for a press operation in electronics assembly, safely testing different engagement distances before finalizing the mechanical stops.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-100B the Right Cylinder?
When sizing this actuator, note that dropping to a 25 mm bore reduces the 0.5 MPa push force to 245.4 N, while stepping up to a 40 mm bore increases it to 628.3 N. If your application never requires altering the end position, a fixed-stroke ACQ cylinder will accomplish the same task. To order this adjustable version correctly, confirm the 32 mm bore, the 100 mm full stroke, the 100 mm adjustment window, the male M14x1.5 rod thread, and the absence of the -S magnet option.
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 ACQJ32X100-100B FAQ
This model provides a push force of 402.1 N and a pull force of 301.6 N at 0.5 MPa, with a push of 562.9 N at 0.7 MPa and a maximum push of 82 kgf at 1.0 MPa. The usable extend range is 0 to 100 mm, set via the 100 mm adjustment window, while the retract stroke remains fixed at the full 100 mm.
The external M12x1.25 threaded stop with lock nut mechanically limits how far the rod extends, shortening the stroke length without changing the piston area, so the output force remains identical to a standard ACQ. The fixed NBR elastomer bumper decelerates the load near the stroke end, but a plain ACQ cylinder will not hold its load on air loss; for fail-safe holding, an external rod lock is required.
