Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X250-50B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X250-50B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 250mm 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 ACQJ32X250-50B
The ACQJ32X250-50B is a double-acting JIS compact cylinder featuring an external M12x1.25 threaded stop with a lock nut on the rod-end side. This mechanism limits the extend travel, allowing you to fine-tune the forward end position directly on the machine. The usable extend range spans 200 to 250 mm, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, the output force matches a standard ACQ of the same bore: 402.1 N push and 301.6 N pull at 0.5 MPa. This unit is a long-stroke made-to-order variant, as the 250 mm stroke exceeds the 100 mm standard maximum for the 32 mm bore. It includes a male M14x1.5 piston rod thread for direct load coupling, a fixed NBR elastomer bumper at each end, and PT1/8 ports. The body features magnetic-switch grooves, though this specific configuration ships without a magnet.

| Bore size | Ø32 mm |
| Full stroke | 250 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 ACQJ32X250-50B Is Used
Product Changeover Stops
Quickly dial in the extend stroke from 200 to 250 mm on packaging lines when switching between different carton sizes, eliminating the need for physical spacer changes.
Long-Reach Press Fixtures
Securely position and clamp materials using the male M14x1.5 rod end, tweaking the exact forward clamping position on the fly to accommodate varying material thicknesses.
Prototype End-Position Tuning
Test and establish optimal extend endpoints during machine prototyping, fine-tuning the 250 mm travel by up to 50 mm without machining new components.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X250-50B the Right Cylinder?
When sizing this model, consider the ACQJ40X250-50B for greater thrust, delivering 628.3 N push at 0.5 MPa, or the ACQJ25X250-50B for a smaller footprint with 245.4 N push. If your application never requires end-position adjustments, a fixed-stroke ACQ32X250 cylinder provides the same force in a simpler package. To order, confirm the 32 mm bore, 250 mm full stroke, 50 mm adjustable window, male rod thread (-B), and note that no magnet (-S) is included.
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 ACQJ32X250-50B 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 250 mm with a 50 mm adjustable window, giving a usable extend range of 200-250 mm. The piston rod is 16 mm with a male M14x1.5 thread, the adjuster thread is M12x1.25, and the port is PT1/8.
No, the adjuster only limits the extend stroke length; the force remains identical to a standard ACQ32 cylinder because the piston area is unchanged. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions. Note that this model ships without a sensor magnet, though the body retains switch grooves for adding sensors if needed.
