Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 175mm 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 ACQJ40X175-10SB
The AirTAC ACQJ40X175-10SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the EXTEND end position. Featuring a 175mm full stroke and a 10mm adjustment window, the usable extend range spans 165-175mm. The RETRACT stroke remains completely unaffected. This long-stroke made-to-order variant exceeds the 100mm standard maximum for this bore, accommodating specialized spacing requirements.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore: 628.3N push and 527.8N pull at 0.5MPa. It includes a Ø16mm piston rod with a male M14x1.5 thread for direct load coupling, and a built-in magnet (-S) for position sensing. Fixed NBR elastomer bumpers at each end decelerate the load without requiring adjustable air cushions.

| Bore size | Ø40 mm |
| Full stroke | 175 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ40X175-10SB Is Used
CNC Lathe Changeover
Dial in the extend stroke from 165 to 175mm during product family changeovers without swapping out the entire cylinder body.
Sorting Diverter Setup
Tune the pusher end position on-site to accommodate varying package sizes on a packaging line sorting conveyor.
Assembly Fixture Tuning
Adjust the end stop to test trial end positions for clamping pressure on custom assembly fixtures.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-10SB the Right Cylinder?
When sizing this cylinder, consider the 628.3N push force at 0.5MPa. A smaller bore 32 provides 402.1N push, whereas a larger bore 50 yields 981.8N push. If your extend position never varies, a fixed-stroke ACQ is sufficient. Confirm your ordering essentials: 40mm bore, 175mm full stroke, 10mm window, male rod thread (-B), and magnet (-S). Note that a plain ACQ-type does not hold its load on air loss; for a fail-safe hold, specify an external rod lock or pilot-operated check valve.
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 ACQJ40X175-10SB FAQ
The push force is 628.3N and pull is 527.8N at 0.5MPa (879.6N push at 0.7MPa), with a maximum push of 128kgf at 1.0MPa. The 175mm full stroke has a 10mm window, allowing a usable extend range of 165-175mm. The rod is Ø16mm with a male M14x1.5 thread, and the external adjuster thread is M12x1.25.
No, the adjuster changes only the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers at each end for deceleration instead of adjustable air cushions. The built-in magnet works with reed or electronic solid-state switches.
