About the Airtac SAI50 Standard Cylinder SAI50X100SFTC
The AirTAC SAI50X100-S is a double-acting ISO 15552 profile cylinder engineered for standardized mounting and robust actuation. Delivering a push force of 982 N at 0.5 MPa, this 50 mm bore unit is built around an extruded aluminum barrel without tie rods. The 100 mm stroke provides an optimal balance of extension and retraction for mid-range automation tasks.
Because this variant includes the -S magnet, it integrates seamlessly with CMSE and DMSE reed switches housed in the sensor grooves machined into both sides of the barrel. The standard carbon steel piston rod offers high tensile strength for repeated cycling, while the adjustable air cushions at both ends ensure smooth deceleration.

Where the Airtac SAI50 Standard Cylinder SAI50X100SFTC Is Used
Component Clamping
Provides reliable 982 N clamping force at 0.5 MPa for securing mid-sized metal or composite parts during CNC machining and assembly processes.
Package Diverting
Actuates sorting arms or pusher plates on packaging lines, utilizing the 100 mm stroke to redirect products between adjacent conveyor belts efficiently.
Material Handling
Drives lifting arms and gripper assemblies in automated palletizers, where the integrated FTC trunnion mount accommodates pivoting articulation.
Is the Airtac SAI50 Standard Cylinder SAI50X100SFTC the Right Cylinder?
Selecting this 50 mm bore is ideal when an application requires more power than a 40 mm cylinder (which provides 628 N at 0.5 MPa) but lacks the physical space for a 63 mm unit. The 100 mm stroke length is highly versatile, fitting seamlessly into compact machinery without the side-load risks associated with longer extensions.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard cylinder sharing this mounting interface. This specific configuration features a PT tapered port thread, an FTC trunnion mounting accessory, and the -S magnet option for position sensing. Note that standard air cushions only decelerate the piston; they do not hold a load. If the application requires position holding without live air pressure, consider the SAIL or BSAI locking variants.
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 SAI50 Standard Cylinder SAI50X100SFTC FAQ
At a standard operating pressure of 0.5 MPa, this 50 mm bore cylinder generates a push force of 982 N and a pull force of 825 N. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X100-S is dimensionally interchangeable per ISO 15552. You can drop it into existing tooling designed for standard profile cylinders of the same bore and stroke, utilizing the FTC trunnion mount and PT ports.
