Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-100SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-100SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 300mm 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 ACQJ32X300-100SB
The ACQJ32X300-100SB is a double-acting JIS compact cylinder featuring a 32mm bore and a 300mm stroke. As a long-stroke made-to-order variant exceeding the standard 100mm maximum for this bore, it incorporates an external threaded stop with a lock nut to regulate the extend end position. You can fine-tune the usable extend range from 200mm up to the full 300mm on the machine, while the retract stroke remains unaffected.
Because the adjuster only alters travel length and not the piston area, output force stays identical to a standard ACQ of this size. The unit pushes 402.1N and pulls 301.6N at 0.5 MPa, rising to 562.9N at 0.7 MPa, with a maximum push capacity of 82kgf at 1.0MPa. It features a male M14x1.5 rod end for direct load coupling, an M12x1.25 adjuster thread, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.

| 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 ACQJ32X300-100SB Is Used
Variable Length Stop Fixtures
Ideal for machining fixtures requiring different clamping depths, allowing operators to dial in the exact extend position from 200 to 300mm without swapping out hardware components.
Product Changeover Stops
Enables rapid format adjustments on packaging lines by turning the external M12x1.25 stopper screw to accommodate varying package sizes on the fly.
Prototype Positioning
Provides testing flexibility on new automated machinery by letting engineers safely trial different extend endpoints during the initial commissioning phase.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-100SB the Right Cylinder?
This 32mm bore delivers 402.1N of push force at 0.5MPa, sitting neatly between the 20mm bore (157.1N push) and the 40mm bore (628.3N push). If your application never requires end-position adjustments, a fixed-stroke ACQ cylinder will suffice and reduce mechanical complexity. When ordering this adjustable variant, confirm the 32mm bore, 300mm full stroke, 100mm adjustment window, the -S magnet for sensor tracking, and the -B male M14x1.5 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 ACQJ32X300-100SB FAQ
This model delivers a push force of 402.1N and a pull force of 301.6N at 0.5MPa, a push of 562.9N at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The usable extend range is 200-300mm, achieved by shortening the full 300mm stroke by up to the 100mm adjustment window.
No, the adjuster only limits the extend stroke length, so the force remains identical to a standard ACQ of the same bore. The cylinder uses fixed elastomer NBR bumpers at each end rather than adjustable air cushions, and the -S magnet works with both reed and electronic solid-state switches.
