About the Airtac SAI100 Standard Air Cylinder SAI100X225
The AirTAC SAI100X225 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 225mm stroke. It generates 3927N of push force and 3681N of pull force at 0.5 MPa, making it well-suited for heavy-duty positioning and high-thrust automation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior while maintaining strict dimensional interchangeability per ISO 15552 standards.
This configuration features a standard carbon steel piston rod and PT tapered port threads. The barrel includes integrated sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches if position feedback is required later. Standard adjustable air cushions at both ends manage piston kinetic energy, and NBR seals ensure reliable service across standard industrial temperature ranges.

Where the Airtac SAI100 Standard Air Cylinder SAI100X225 Is Used
Heavy-Duty Pressing
Provides 3927N of thrust at 0.5 MPa for securely seating bearings and bushings into heavy housings.
Large Clamp Actuation
Drives robust clamping mechanisms on large machining fixtures where high holding power is essential.
Pallet Stopping
Acts as a heavy-duty stopper arm for large pallets on conveyor lines, absorbing momentum effectively.
Is the Airtac SAI100 Standard Air Cylinder SAI100X225 the Right Cylinder?
Selecting this 100mm bore over the smaller 80mm variant provides a significant thrust jump, increasing push force from 2513N to 3927N at 0.5 MPa. If your application requires less force, dropping to the 80mm bore saves space and air consumption. This 225mm stroke falls below the 300mm threshold, so standard rod-bearing bending is minimal, though side loads should still be minimized through proper mechanical alignment.
As a true ISO 15552 cylinder, this model serves as a drop-in replacement for other ISO 15552 profile cylinders. To match this exact unit, specify a 100mm bore, 225mm stroke, G1/2 port, PT thread type, and standard carbon steel rod. Because it lacks a magnet suffix (-S), it cannot host reed sensors without modification. Note that this standard cylinder relies on air pressure to hold position; it will drop its load if air is exhausted. For fail-safe holding, consider the SAIL variant.
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 SAI100 Standard Air Cylinder SAI100X225 FAQ
At a standard 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At the maximum 1.0 MPa pressure, the theoretical push force reaches 801 kgf.
Yes. The SAI series is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders. You can use it as a drop-in replacement by matching the 100mm bore, 225mm stroke, and G1/2 port size.
