Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-40B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-40B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X100-40B
The AirTAC ACQJ40X100-40B is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 60 mm up to the full 100 mm stroke directly on your equipment, while the retract stroke remains unaffected. It features a male M14x1.5 piston rod end that couples directly to your load.
Because the adjuster alters stroke length only, the piston area stays the same, meaning the force output is identical to a standard ACQ of this bore. The 16 mm rod uses PT1/8 ports, and the body includes fixed elastomer NBR bumpers at both ends for end-of-stroke deceleration. Please note this specific configuration ships without a magnet, though the body retains standard sensor grooves for adding external switches if needed later.

| 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 (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 ACQJ40X100-40B Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC machining fixture during setup, accommodating varying part sizes without swapping out cylinder hardware.
Product Changeover Diverters
Adjust the stroke of a conveyor sorting gate on the fly to handle different package widths during rapid production line changeovers.
Prototype Press Positioning
Establish the precise lower end-position for a prototype assembly press, safely testing different material compression depths before finalizing the design.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-40B the Right Cylinder?
When sizing this 40 mm bore unit, consider the adjacent options: a 32 mm bore yields 402.1 N push force at 0.5 MPa, whereas a 50 mm bore provides 981.8 N. If your application never requires on-the-fly end-position changes, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable variant, confirm the 40 mm bore, 100 mm full stroke, 40 mm adjuster window, the male rod thread (-B), and that no magnet is required.
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 ACQJ40X100-40B FAQ
The usable extend range is 60-100 mm. The external adjuster has an M12x1.25 thread. Force is identical to a standard ACQ: 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, with a maximum push of 128 kgf at 1.0 MPa.
An external threaded screw with a lock nut limits the extend stroke without changing the piston area, so force remains constant. Fixed elastomer bumpers decelerate the rod near stroke end. A plain ACQ-type cylinder will not hold its load if air is lost; use an external rod lock or pilot-operated check valve for fail-safe holding.
