Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-50B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-50B 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 ACQJ40X60-50B
The AirTAC ACQJ40X60-50B is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend stroke. You can fine-tune the forward end position directly on the machine without swapping parts. The usable extend range is 10-60 mm, built from the 60 mm full stroke minus the 50 mm adjustment window, while the retract stroke remains completely unaffected.
Because the piston area stays the same, output force equals a standard ACQ of this bore: 628.3 N push and 527.8 N pull at 0.5 MPa. This male-thread variant provides an M14x1.5 rod end for direct load coupling. The body incorporates fixed NBR elastomer bumpers at each end for end-of-travel deceleration, and it retains sensor grooves, though this specific unit ships without a magnet.

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 ACQJ40X60-50B Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC fixture during setup. The external stop allows 10-60 mm of forward travel to accommodate varying raw part dimensions without machining new spacers.
Product Changeover Diverters
Adjust the stroke length on a packaging line diverter when switching between different package widths. The lock nut secures the new end position for reliable repetitive motion.
Assembly Press Trials
Set trial end positions on an assembly press to test insertion depths. The male M14x1.5 rod threads directly into tooling, letting operators find the perfect seating force before finalizing the setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-50B the Right Cylinder?
Choosing this 40 mm bore yields 879.6 N push at 0.7 MPa. Stepping down to a 32 mm bore drops the 0.5 MPa push to 402.1 N, whereas scaling up to a 50 mm bore raises it to 981.8 N. If your application never requires altering the forward travel, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 40 mm bore, 60 mm full stroke, 50 mm window, the male M14x1.5 rod thread, and whether you need the -S magnet for position 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 ACQJ40X60-50B 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 60 mm with a 50 mm adjustment window, resulting in a usable extend range of 10-60 mm.
No, the adjuster only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers for deceleration, not an adjustable air cushion. Note that a plain ACQ-type does not hold its load on air loss; for fail-safe holding, an external rod lock or pilot-operated check valve is required.
