Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X15-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X15-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 15mm 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 ACQJ40X15-10SB
The AirTAC ACQJ40X15-10SB is a double-acting JIS compact cylinder with a 40mm bore and a 15mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 5-15mm. The retract stroke remains unaffected by this mechanism. Because the piston area is unchanged, the force is identical to a standard ACQ of this bore, delivering 628.3N push and 527.8N pull at 0.5 MPa.
This model includes the -S magnet for compatibility with reed or solid-state switches, and the -B male rod-end thread (M14x1.5) for direct load coupling. It features a fixed elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The standard PT1/8 port and 16mm piston rod ensure robust pneumatic performance within a compact riveted body design.

| Bore size | Ø40 mm |
| Full stroke | 15 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 ACQJ40X15-10SB Is Used
Fixture Position Tuning
Dial in exact clamping distances on machining fixtures without machining new spacers or swapping components.
Product Changeover Stops
Adapt extend endpoints rapidly on packaging lines when handling different carton sizes or product heights.
Trial End Positions
Set experimental extend limits safely during machine prototyping to verify travel before finalizing hard stops.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X15-10SB the Right Cylinder?
At 0.5 MPa, this 40mm bore provides 628.3N push force. Stepping down to a 32mm bore yields 402.1N push, while moving up to a 50mm bore offers 981.8N. If your application requires a fixed extend position every cycle without tuning, a standard ACQ40X15 cylinder will suffice. When ordering this adjustable unit, confirm the 40mm bore, 15mm full stroke, 10mm adjustment window, the required -S magnet, and the -B male rod 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 ACQJ40X15-10SB FAQ
It delivers 628.3N push and 527.8N pull at 0.5 MPa, 879.6N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The full stroke is 15mm with a 10mm adjustment window, allowing a usable extend range of 5-15mm.
An M12x1.25 external threaded stop with a lock nut limits the extend stroke length only. It does not change the piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected, and fixed elastomer bumpers handle deceleration at both ends.
