Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-100S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-100S 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 ACQJ32X300-100S
The ACQJ32X300-100S is a double-acting, single-rod JIS compact cylinder built for applications requiring on-machine extend-position tuning. Featuring a 32mm bore and a 300mm total stroke, this made-to-order long-stroke variant utilizes an external M12x1.25 threaded stop with a lock nut. You can fine-tune the forward stroke anywhere within a 200 to 300mm usable range without swapping components. The retract distance remains completely unaffected by this adjustment.
Because the piston area stays constant, output force matches a standard ACQ exactly, yielding 402.1N push and 301.6N pull at 0.5MPa. The unit includes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and integrates a piston magnet (-S) for position sensing. This magnet is fully compatible with both reed and electronic solid-state switches. Fluid supply should be filtered to 40um, operating within 0.15-1.0MPa pressure limits.

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 ACQJ32X300-100S Is Used
Multi-Fixture Machining Stops
Dial in the extend stroke from 200 to 300mm on a CNC loading station to accommodate varying raw part lengths without fabricating custom hard stops.
Product Changeover Diverter
Quickly reposition a sorting gate on a packaging conveyor by twisting the external M12x1.25 adjuster to match new carton dimensions on the fly.
Long-Reach Press Setup
Establish trial end positions for a 32mm bore clamping mechanism on an assembly press, testing different grip depths before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-100S the Right Cylinder?
When sizing this unit, consider the 32mm bore's force profile: it delivers 402.1N push at 0.5MPa, sitting between a 25mm bore (245.4N push) and a 40mm bore (628.3N push). If your extend endpoint never varies, a fixed-stroke ACQ cylinder provides the same output in a shorter body. If you need exact forward positioning across different setups, this adjustable model is ideal. Confirm your ordering essentials: 32mm bore, 300mm full stroke, 100mm adjuster window, the -S magnet option, and the default female M8x1.25 rod-end thread. Note that at 300mm, this is a special long-stroke configuration exceeding the 100mm standard maximum for this bore.
Quick checklist

- ✓ 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 ACQJ32X300-100S FAQ
This 32mm bore cylinder has a 300mm full stroke with a 100mm adjustable window, giving a usable extend range of 200-300mm. Force is identical to a standard ACQ: 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 port size is PT1/8.
An external threaded stop and lock nut mechanically limits how far the rod extends, shortening the forward stroke without changing piston area, so force remains unchanged. The retract stroke is unaffected. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. For high-speed loads, add an external shock absorber. Note that a standard compact cylinder does not hold loads on air loss; use an external rod lock for fail-safe holding.
