About the Airtac SAI100 Standard Air Cylinder SAI100X155S
The AirTAC SAI100X155-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Operating at 0.5 MPa, it provides a robust push force of 3927 N and a pull force of 3681 N. The 155 mm stroke is ideal for mid-length actuation in demanding material handling environments.
Featuring an integrated magnet for position sensing, this model directly supports CMSE and DMSE reed switches via dual sensor grooves on the extruded aluminum barrel. The standard carbon steel piston rod ensures high tensile strength, while the PT tapered port thread guarantees a reliable, leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100X155S Is Used
Heavy-Duty Stamping
Generates 5497 N of thrust at 0.7 MPa for securely pressing bearings and bushings into heavy metal housings.
Pallet Diverting
Provides the robust 155 mm stroke and high lateral force capacity required to redirect heavy loaded pallets on high-speed conveyor lines.
Automated Clamping
Holds large automotive components firmly in place during machining operations, utilizing its 100 mm bore for maximum rigidity.
Is the Airtac SAI100 Standard Air Cylinder SAI100X155S the Right Cylinder?
Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore cylinder handles substantial loads. If your application requires less force, stepping down to an 80 mm bore yields 2513 N, conserving space and air consumption. Conversely, moving up to a 125 mm bore provides 6136 N for heavier masses.
Because the stroke is 155 mm, side-load stress on the rod bearing is moderate but manageable. Ensure proper alignment with external guides to prevent premature wear. If a process demands position retention without constant air pressure, utilize the SAIL variant with an air-released lock or a BSAI clamp-lock cylinder instead of relying on standard air cushions.
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.
