Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 10mm 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 ACQJ40X10-10SB
The AirTAC ACQJ40X10-10SB is a double-acting JIS compact cylinder featuring a 10mm full stroke and an external extend stop. An external threaded adjuster with an M12x1.25 thread and lock nut lets you fine-tune the forward end position from 0 to 10mm directly on the machine, while the retract stroke remains unaffected. Because the piston area stays the same, output force is identical to a standard ACQ of this bore.
This 40mm bore unit delivers 628.3N push and 527.8N pull at 0.5MPa. It includes an -S piston magnet compatible with reed or solid-state switches, and a -B male M14x1.5 rod end for direct load coupling. Deceleration relies on a fixed NBR elastomer bumper at each end, not an adjustable air cushion.

| 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 ACQJ40X10-10SB Is Used
Machine Tending Setup
Dial in the exact 0-10mm extend position during initial fixture setup on CNC load stations without machining custom spacers.
Product Changeover Stops
Quickly alter the extend endpoint within the 10mm window to accommodate different workpiece lengths on a packaging line.
Assembly Press Trials
Test trial end positions for pressing bearings into housings, safely limiting the forward travel to prevent part damage.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10SB the Right Cylinder?
When sizing this 40mm bore, the adjacent ACQ option down is 32mm, providing 402.1N push at 0.5MPa. Stepping up to the 50mm bore yields 981.8N push at 0.5MPa. If your application requires a fixed 10mm extend position without any on-machine tuning, a standard ACQ40X10 will suffice. To order this adjustable version, confirm the 40mm bore, 10mm full stroke, 10mm window, -S magnet, and -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 ACQJ40X10-10SB FAQ
The usable extend range is 0-10mm (10mm full stroke minus a 10mm window). It delivers 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 retract stroke is unaffected by the adjuster.
An external M12x1.25 threaded stop with a lock nut limits the forward travel, allowing on-machine endpoint tuning without changing parts. The force remains identical to a standard ACQ because the adjuster only changes stroke length, not piston area. Deceleration is handled by a fixed elastomer bumper, not an adjustable air cushion.
