Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 80mm 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 ACQJ40X80-10S
The AirTAC ACQJ40X80-10S is a double-acting JIS compact cylinder with a tunable extend stroke. An external M12x1.25 threaded stop and lock nut limits how far the rod travels out, giving a usable extension range of 70-80 mm from the 80 mm full stroke. The retract movement remains completely unaffected by this adjustment.
Because the piston area stays constant, output force equals a standard ACQ of the same bore, delivering 628.3 N push and 527.8 N pull at 0.5 MPa. The unit includes a -S piston magnet for position sensing with reed or solid-state switches, and relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration.

| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

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 ACQJ40X80-10S Is Used
Machining Fixture Tuning
Dial in the exact clamping extension on a milling fixture without fabricating new spacer blocks during part changeovers.
Carton Sealing Stops
Shift the pressing end position on packaging equipment to accommodate varying box heights directly on the floor.
Assembly Press Setup
Establish trial end positions for pressing bearings on automated lines, allowing rapid shortening of the stroke by up to 10 mm.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10S the Right Cylinder?
Selecting this bore provides 628.3 N push at 0.5 MPa, sitting between the smaller 32 mm option (402.1 N push) and the larger 50 mm bore (981.8 N push). A fixed-stroke ACQ is sufficient if your extend end position never requires on-machine shifting. When ordering, confirm the 40 mm bore, 80 mm full stroke, 10 mm adjuster window, -S magnet, and 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 ACQJ40X80-10S FAQ
It delivers 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 80 mm, but the external stop allows the usable extend range to be shortened to 70-80 mm.
No, the adjuster only limits the extend stroke length, leaving the output force identical to a standard ACQ. Deceleration is handled by a fixed elastomer bumper at each end, not an adjustable air cushion.
