Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-30B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-30B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 40mm 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 ACQJ32X40-30B
The ACQJ32X40-30B is a double-acting JIS compact cylinder featuring a 32mm bore and a 40mm full stroke. An external threaded stop with a lock nut limits the extend end position, allowing you to fine-tune the usable extend range from 10mm up to 40mm directly on the machine without changing parts. The retract stroke remains unaffected by this adjustment.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore, delivering a push of 402.1N at 0.5MPa. This specific variant includes a male M14x1.5 rod-end thread for direct load coupling and ships without a magnet. It utilizes a fixed elastomer bumper at each end rather than an adjustable air cushion, operating reliably at 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 |

| 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 ACQJ32X40-30B Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC machining fixture to accommodate raw material thickness variations without swapping hardware.
Product Changeover Diverters
Quickly reposition a conveyor sorting gate during packaging line product changeovers by rotating the external stop screw to the new required extend length.
Assembly Press Trial Positions
Establish optimal pressing depths on automated assembly equipment during prototype runs by testing various extend end positions safely before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-30B the Right Cylinder?
When sizing this actuator, consider the neighboring bores: a 25mm bore provides 245.4N push, while a 40mm bore yields 628.3N push at 0.5MPa. If your application never requires end-position variance, a fixed-stroke ACQ cylinder will suffice. To order this adjustable version correctly, confirm the 32mm bore, 40mm full stroke, 30mm adjustment window, the male rod thread, and whether you need the magnet option for sensor grooves.
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 ACQJ32X40-30B FAQ
This 32mm bore cylinder provides a push force of 402.1N and a pull force of 301.6N at 0.5MPa, with a push of 562.9N at 0.7MPa and a maximum push of 82kgf at 1.0MPa. The full stroke is 40mm, but the external stop allows you to adjust the usable extend range from 10mm to 40mm via a 30mm window.
The external M12x1.25 threaded stop with lock nut physically limits how far the rod extends, shortening the stroke length without altering the piston area, so force remains identical to a standard ACQ. Deceleration is handled by a fixed elastomer bumper at each end, not an adjustable air cushion, and since this model lacks a magnet, it will not trigger reed or solid-state switches.
