Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-20SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-20SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm 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 ACQJ32X175-20SB
The AirTAC ACQJ32X175-20SB is a double-acting JIS compact cylinder with a 175mm stroke that exceeds the standard 100mm maximum for this bore, making it a made-to-order long-stroke variant. An external threaded stop with a lock nut limits the extend end position, allowing you to fine-tune the usable extend range from 155mm up to the full 175mm without changing parts. The retract stroke remains unaffected.
Because the piston area is unchanged, force is identical to a standard ACQ of this bore, delivering 402.1N push and 301.6N pull at 0.5 MPa. This unit includes a built-in piston magnet compatible with reed or solid-state switches, and a male M14x1.5 rod-end thread for direct load coupling. It features fixed NBR elastomer bumpers at both ends for deceleration, operating at speeds of 30-500 mm/s.

| Bore size | Ø32 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 |

| 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 ACQJ32X175-20SB Is Used
Machining Fixture Clamping
Dial in the exact clamping reach on a CNC fixture during product-changeover, shortening the extend stroke within the 155-175mm window to accommodate varying raw material thicknesses.
Transfer Line Diverter
Adjust the pusher end position on a conveyor sorting station to handle different package sizes without swapping out the entire cylinder assembly.
Carton Sealing Mechanism
Fine-tune the folding arm extension on a packaging line to test trial end positions and find the optimal sealing contact point for new carton dimensions.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-20SB the Right Cylinder?
When configuring this 32mm bore cylinder, verify your space can accommodate the 175mm long-stroke body, and confirm the 20mm adjustable window suits your setup tolerances. If your application only requires a fixed end position, a standard ACQ32X175 cylinder without the external adjuster would suffice. For sizing, dropping to a 25mm bore reduces push force to 245.4N at 0.5 MPa, while stepping up to a 40mm bore increases it to 628.3N. Ordering essentials include the 32mm bore, 175mm stroke, 20mm window, S magnet option, 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 ACQJ32X175-20SB FAQ
This 32mm bore cylinder provides 402.1N push and 301.6N pull force at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 175mm, and the external adjuster allows the usable extend range to be shortened by up to 20mm, resulting in a 155-175mm usable extend range.
The external M12x1.25 threaded stop with lock nut limits the extend length only, meaning the force remains identical to a standard ACQ because the piston area is unchanged. The retract stroke is unaffected. Deceleration is handled by fixed NBR elastomer bumpers at each end rather than adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
