Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-10B 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 ACQJ40X60-10B
The AirTAC ACQJ40X60-10B is a double-acting JIS compact cylinder with a 60mm full stroke and a male M14x1.5 piston rod. An external M12x1.25 threaded stop and lock nut lets you fine-tune the extend end position on the machine, providing a usable extend range of 50 to 60mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore: 628.3N push and 527.8N pull at 0.5MPa. The body uses a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. It operates at 30-500mm/s and features sensor grooves, though this specific SKU ships without a magnet.

| 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 |

| 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 ACQJ40X60-10B Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC machining center during setup. The external stop allows 50-60mm extend positioning to accommodate varying part heights without swapping cylinders.
Packaging Changeover
Adjust the product push-off distance on a packaging line when switching carton sizes. The lock nut secures the new extend endpoint rapidly to minimize line downtime.
Assembly Press Trials
Test different insertion depths on an automated assembly press. You can tune the extend stroke by up to 10mm to find the optimal pressing position before finalizing the mechanical setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-10B the Right Cylinder?
Selecting this 40mm bore provides 628.3N push at 0.5MPa; stepping down to a 32mm bore drops push to 402.1N, while a 50mm bore raises it to 981.8N. If your machine never needs end-position tuning, a fixed-stroke ACQ cylinder is simpler and suffices. When ordering this adjustable version, confirm the 40mm bore, 60mm full stroke, 10mm window, the male rod thread, and whether you need the -S magnet option for electronic or reed switch sensing.
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 ACQJ40X60-10B FAQ
The usable extend range is 50-60mm (60mm full stroke minus the 10mm window). Force is identical to a standard ACQ: 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa.
The M12x1.25 threaded stop with lock nut mechanically limits the extend distance without changing the piston area, so force remains unchanged. The cylinder uses fixed NBR elastomer bumpers, not adjustable air cushions. It will not hold a load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
