About the Airtac SAI100 Standard Air Cylinder SAI100AX375S
The AirTAC SAI100X375-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering 3927 N of push force at 0.5 MPa, this 100mm bore actuator handles substantial loads over its 375mm stroke. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that matches standardized ISO 15552 mounting dimensions exactly.
This specific configuration includes a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance in humid or washdown environments. The -S suffix denotes an integrated magnet, allowing seamless position tracking with CMSE or DMSE reed switches fitted directly into the dual sensor grooves. Fluid ports are PT tapered threads.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX375S Is Used
Heavy-Duty Stamping
Provides the 3927 N push force required to seat bearings or form light gauge metal sheets in automated presses.
Pallet Diversion
Uses the 375mm stroke to push heavy product pallets off a main conveyor line into a secondary packaging zone.
Large Gate Actuation
Opens and closes substantial machine safety gates or process chutes where the 100mm bore ensures positive momentum.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX375S the Right Cylinder?
At 0.5 MPa this 100mm bore yields 3927 N of thrust; stepping down to the 80mm bore drops that to 2513 N, while the massive 125mm bore pushes 6136 N. Choose the 100mm when your payload sits firmly in the 400 kg force bracket. Because the 375mm stroke creates a long extension, avoid side-loading the rod—unsupported rods bend under lateral stress. Mount external guide rails or select a guided cylinder to prevent rod-bearing wear.
This actuator is a drop-in replacement for any ISO 15552 cylinder with a 100mm bore, 375mm stroke, G1/2 port, and matching mounting accessories like FA flanges or TC trunnions. Remember that standard pneumatic cushions only decelerate the piston at end-of-stroke; they do not hold loads. If your application loses air pressure and must not drift downward, specify the SAIL pneumatic lock or BSAI clamp-lock variant instead of relying on this standard cylinder.
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.
