Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50B 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 ACQJ32X175-50B
The AirTAC ACQJ32X175-50B is a double-acting, single-rod JIS compact cylinder built for made-to-order long-stroke applications. It features an external M12x1.25 threaded stop with a lock nut on the rod-end side, allowing you to fine-tune the extend end position directly on the machine. The usable extend range spans 125-175 mm, shortening the full 175 mm stroke by up to 50 mm without swapping parts. The retract stroke remains completely unaffected. Because the piston area is unchanged, force is identical to a standard ACQ, delivering 402.1 N push and 301.6 N pull at 0.5 MPa.
This variant includes a male M14x1.5 piston rod end (-B) for direct load coupling and uses a PT1/8 port. It operates at 30-500 mm/s within a -20 to +70 C environment. The body incorporates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. While shipping without a magnet, the cylinder body retains sensor grooves for adding external reed or solid-state switches if needed later.

| 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 ACQJ32X175-50B Is Used
Multi-Height Machining Stops
Adjust the extend position from 125 to 175 mm on CNC machining centers to accommodate varying raw material lengths without fabricating new hard stops.
Product Changeover Diverter
Fine-tune the extend stroke on packaging conveyor diverter arms during product format changes, ensuring precise routing without mechanical rebuilds.
Long-Reach Clamping Arm
Utilize the 175 mm extended reach for clamping large workpieces or fixtures, tweaking the final clamping position on the fly via the external lock nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50B the Right Cylinder?
This 32 mm bore provides 562.9 N of push force at 0.7 MPa. If your application requires less force, consider the next bore down: a 25 mm unit yields 245.4 N push at 0.5 MPa. For heavier demands, stepping up to a 40 mm bore provides 628.3 N push at 0.5 MPa. Note that the 175 mm stroke exceeds the standard 100 mm maximum for this bore, making this a long-stroke, made-to-order variant. If on-site extend tuning is unnecessary, a fixed-stroke ACQ cylinder will suffice. When ordering, confirm the 32 mm bore, 175 mm full stroke, 50 mm adjustable window, male M14x1.5 rod thread, and the absence of a magnet.
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 ACQJ32X175-50B FAQ
It delivers 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 175 mm, but the external adjuster allows you to shorten the extend stroke by up to 50 mm, giving a usable extend range of 125-175 mm.
The external M12x1.25 threaded stop limits only the extend stroke; force remains identical to a standard ACQ because the piston area is unchanged. The cylinder uses fixed elastomer bumpers, not adjustable air cushions. Note that a plain ACQ-type cylinder will not hold its load on air loss, so an external rod lock or pilot-operated check valve is recommended for fail-safe holding.
