Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-30S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-30S 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 ACQJ32X100-30S
The AirTAC ACQJ32X100-30S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend stroke. You get a usable extension range of 70-100mm, letting you shorten the full 100mm stroke by up to 30mm directly on your equipment. The retract stroke remains completely unaffected. Because the piston area stays the same, output force equals a standard ACQ of this bore, delivering 402.1N push and 301.6N pull at 0.5MPa.
This 32mm bore unit uses a 16mm rod and PT1/8 porting. It includes a fixed elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The -S suffix indicates a built-in piston magnet compatible with reed or electronic solid-state switches via the body grooves. Operating pressure spans 0.15-1.0MPa, with a proof rating of 1.5MPa across a -20 to +70C temperature range.

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 ACQJ32X100-30S Is Used
Machining Fixture Stops
Dial in the exact extend position within the 70-100mm window to clamp raw castings of varying widths on a CNC milling station without swapping hardware.
Packaging Format Changeover
Adjust the extend stroke on the fly to push different carton sizes into a sealing head, using the external stop to set precise product spacing.
Assembly Press Tonnage
Set trial end positions for pressing bearings on an automated line, tweaking the 30mm window to find the exact seating depth before finalizing the cycle.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-30S the Right Cylinder?
When sizing this actuator, verify your force needs against the 402.1N push at 0.5MPa. Stepping down to a 25mm bore yields 245.4N push, while moving up to a 40mm bore provides 628.3N push. If your application never requires shifting the end position, a fixed-stroke ACQ cylinder is simpler and sufficient. To order this adjustable version correctly, confirm the 32mm bore, 100mm full stroke, 30mm adjuster window, the -S magnet option, and the default female M8x1.25 rod-end 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 ACQJ32X100-30S FAQ
It delivers 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 100mm with a -30mm window, giving a usable extend range of 70-100mm. The piston rod is 16mm, the port is PT1/8, the female rod-end thread is M8x1.25, and the external adjuster thread is M12x1.25.
No, the external threaded stop only limits how far the rod extends, so the force remains identical to a standard ACQ. The cylinder uses a fixed elastomer bumper for deceleration, not an adjustable air cushion. Also, it will not hold a load if air pressure is lost; for fail-safe load holding, you must add an external rod lock or pilot-operated check valve.
