About the Airtac SAI50 Standard Cylinder SAI50BX150S
The AirTAC SAI50X150-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 150 mm stroke provides the exact extension needed for mid-range material handling and indexing tasks. Built with an extruded aluminum barrel, it eliminates traditional tie-rods for a cleaner exterior.
This specific configuration includes a SUS304 stainless steel piston rod (code B) for superior corrosion resistance in washdown or humid settings. It is equipped with a magnet (-S) to trigger CMSE or DMSE sensors via the dual side grooves, and uses PT tapered port threads to ensure a mechanically tight pneumatic seal.

Where the Airtac SAI50 Standard Cylinder SAI50BX150S Is Used
Stainless Component Lifting
Ideal for lifting and transferring metal parts in humid environments, utilizing the SUS304 rod to prevent surface corrosion and maintain operational integrity.
Mid-Range Package Diverting
Provides 982 N of push force at 0.5 MPa to reliably divert heavier packages or pallets on a sorting line without requiring high operating pressures.
Sensor-Driven Clamping
Uses the integrated magnet and dual sensor grooves to confirm clamp position with CMSE switches before a machining cycle begins, ensuring safety and precision.
Is the Airtac SAI50 Standard Cylinder SAI50BX150S the Right Cylinder?
Select this 50 mm bore when an application requires stepping up from a 40 mm cylinder (which provides 628 N at 0.5 MPa) to handle heavier payloads without the bulk of a 63 mm unit. The 150 mm stroke is well within the 1200 mm standard maximum, keeping the assembly compact and robust.
Because this is a double-acting cylinder, it relies on continuous air pressure to move and hold the rod; if air is exhausted, the piston will drift. The adjustable air cushions at both ends only serve to decelerate the piston near stroke end and do not function as a locking brake. For true load-holding without live pressure, consider the SAIL or BSAI 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 SAI50BX150S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X150-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts designed for standard ISO 15552 profile cylinders, matching the 50 mm bore, 150 mm stroke, and PT port interface.
