Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X90-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X90-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 90mm 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 ACQJ40X90-10B
The ACQJ40X90-10B is a double-acting JIS compact cylinder featuring a male-thread piston rod end (M14x1.5) that couples directly to your load. It incorporates an external M12x1.25 threaded stop with a lock nut on the extend side, allowing on-machine end-position tuning without swapping components. You can shorten the forward stroke by up to 10 mm, yielding a usable extend range of 80 to 90 mm, while the retract stroke remains completely unaffected.
Because the piston area stays the same, output force equals a standard ACQ of this bore, delivering 628.3 N push and 527.8 N pull at 0.5 MPa. The unit relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. Although this specific configuration ships without a magnet, the body retains magnetic-switch grooves for adding sensors later.

| 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 ACQJ40X90-10B Is Used
Machining Fixture Clamps
Dial in the exact 80 to 90 mm clamp extension on a CNC fixture to accommodate varying raw material thicknesses without machining custom spacer blocks.
Carton Sealing Stops
Fine-tune the pressing end position on a packaging line during product changeover, ensuring consistent flap folding depth across different box sizes.
Assembly Press Setup
Establish trial end positions for pressing bearings on an assembly line, safely testing the 10 mm adjustment window before finalizing the mechanical stops.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X90-10B the Right Cylinder?
When sizing this 40 mm bore actuator, consider the 32 mm option providing 402.1 N push, or the larger 50 mm bore yielding 981.8 N push at 0.5 MPa if your load demands more power. If your application never requires stroke length changes, a fixed-stroke ACQ series cylinder will achieve the same clamping force. To order the ACQJ variant correctly, confirm the 40 mm bore, 90 mm full stroke, 10 mm adjuster window, the male rod thread, and whether you need the S magnet option for electronic or reed sensors.
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 ACQJ40X90-10B FAQ
This 40 mm bore cylinder provides 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 full stroke is 90 mm with a 10 mm adjustable window, giving a usable extend range of 80 to 90 mm. Operating pressure spans 0.15 to 1.0 MPa.
The external M12x1.25 threaded stop limits only the extend stroke, leaving retract unchanged. Force remains identical to a standard ACQ because the piston area is unaltered. Deceleration relies on a fixed elastomer bumper, and since a plain ACQ-type does not hold its load on air loss, you should add an external rod lock or pilot-operated check valve for fail-safe positioning.
