About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-20
The AirTAC SAIJ32X400-20 is a double-acting ISO 15552 profile cylinder with a 32mm bore and 400mm stroke. A rear stopper screw lets you shorten the travel by up to 20mm, creating a 380-400mm usable window for precise end-position tuning at commissioning. It delivers 402N of push force and 345N of pull force at 0.5 MPa.
This unit uses a SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threading (G1/8). The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a travel stop to set deceleration limits, not as a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-20 Is Used
Machine Setup Tuning
Dial in the exact 380-400mm end-stop during commissioning to perfectly time a pressing or indexing motion without machining new hard stops.
Product Changeover
Quickly adjust the retract position by up to 20mm to accommodate different package sizes on a packaging line.
Variable End Stops
Set precise travel limits for delicate component placement tasks where a fixed 400mm stroke might overtravel and cause damage.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-20 the Right Cylinder?
Choose this 32mm bore model when an application requires 402N of push force at 0.5 MPa. If your process needs less force, stepping down to a 25mm bore (if available) or a 20mm bore reduces footprint, while stepping up to a 40mm bore yields 628N of push force for heavier loads. The 20mm adjustment range is ideal for product changeovers, allowing you to fine-tune the end stop without swapping the cylinder or adding external stops.
For a direct ISO 15552 replacement, match the 32mm bore, 400mm stroke, 20mm adjustment, PT port thread, and your required mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the 400mm stroke is relatively long for a 32mm rod, an external guide is recommended to prevent excessive side-loading on the rod. To hold a load without live air pressure, use an external rod lock or pilot-operated check valve, as the SAIJ adjuster does not function as a brake.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-20 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to trim the effective stroke back by up to 20mm from the nominal 400mm length. This creates a 380-400mm usable travel window, letting you fine-tune the end position without replacing the cylinder.
