Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 60mm 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 ACQJ40X60-40B
The AirTAC ACQJ40X60-40B is a double-acting JIS compact cylinder featuring a male-thread piston rod end (M14x1.5) that couples directly to your load. An external M12x1.25 threaded stop with a lock nut limits the extend end position, allowing you to fine-tune the usable extend range from 20 mm up to the full 60 mm stroke directly on the machine. The retract stroke remains completely unaffected.
Because the piston area is unchanged, the output force is identical to 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 end-of-stroke deceleration rather than an adjustable air cushion. The body includes magnetic-switch grooves, though this specific configuration ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 60 mm |
| 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 ACQJ40X60-40B Is Used
Machining Fixture Stops
Dial in the exact extend position for varying part lengths on a milling fixture without machining new spacer blocks.
Product Changeover Diverter
Quickly reposition a pneumatic sorting gate on a packaging line to handle different carton widths on the fly.
Assembly Press Testing
Safely test and verify the trial end position for a pressing operation before finalizing the mechanical setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40B the Right Cylinder?
When sizing this 40 mm bore, dropping down to a 32 mm bore reduces the push force to 402.1 N at 0.5 MPa, while stepping up to a 50 mm bore increases it to 981.8 N. If your application never requires altering the extend endpoint, a fixed-stroke ACQ cylinder is sufficient and simpler. For this adjustable model, confirm the 40 mm bore, 60 mm full stroke, 40 mm window, male rod thread (-B), and note that a -S magnet must be specified if position sensing is needed.
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 ACQJ40X60-40B FAQ
The usable extend range is 20-60 mm (60 mm full stroke minus the 40 mm window). It provides a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke length only. The piston area remains the same, so the force is identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers for deceleration and does not feature an adjustable air cushion.
