Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-30SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-30SB 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 ACQJ32X175-30SB
The AirTAC ACQJ32X175-30SB is a double-acting JIS compact cylinder with a 175mm long-stroke design, built-in magnet (-S), and a male piston rod end (-B). An external threaded stop with a lock nut restricts the extend end position, yielding a usable forward travel range of 145 to 175mm. The retract movement remains at the full 175mm and is completely unaffected by the stop adjustment.
Because the adjuster only limits travel length without altering piston area, output force stays identical to a standard ACQ of this bore. At 0.5MPa it generates 402.1N of push force and 301.6N of pull force. The unit features a fixed NBR elastomer bumper at each end for end-of-travel deceleration, and the male M14x1.5 rod end threads directly to your load.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-30SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| 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 |
| 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 (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 ACQJ32X175-30SB Is Used
Machining Fixture Stops
Dial in the exact extend position on a CNC clamping fixture during part changeovers without machining new stop collars.
Carton Sealing Turrets
Adjust the forward stroke of a sealing head on the fly to accommodate varying package sizes on a packaging line.
Prototype Press Trials
Find the optimal end position during prototype testing by turning the external M12x1.25 adjuster screw rather than swapping components.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-30SB the Right Cylinder?
This 32mm bore provides 402.1N push at 0.5MPa; sizing down to a 25mm bore yields 245.4N push, while stepping up to a 40mm bore offers 628.3N push. The 175mm stroke exceeds the 100mm standard maximum for this bore, making it a made-to-order long-stroke variant. If exact end positioning is not required, a fixed-stroke ACQ cylinder suffices. Confirm ordering essentials: 32mm bore, 175mm full stroke, 30mm adjuster window, magnet (-S), and male rod thread (-B).
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 ACQJ32X175-30SB FAQ
It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The full stroke is 175mm, but the external stop allows the extend stroke to be shortened by up to 30mm, giving an adjustable extend range of 145 to 175mm.
The external threaded stop limits only the extend length, so force remains identical to a standard 32mm ACQ cylinder. The cylinder uses fixed elastomer bumpers at both ends for deceleration rather than adjustable air cushions. The built-in magnet (-S) works with both reed and solid-state electronic switches.
