About the Airtac SAI50 Standard Cylinder SAI50X150S
The AirTAC SAI50X150-S is a double-acting profile cylinder built to ISO 15552 dimensional standards, providing 982N of push force at 0.5 MPa and 1374N at 0.7 MPa. Its 150mm stroke is ideal for medium-travel positioning tasks. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that resists mechanical debris buildup.
This variant includes a standard magnetic piston (-S) designed to operate seamlessly with CMSE and DMSE reed switches fitted into the dual sensor grooves on both sides of the barrel. It utilizes a standard carbon steel piston rod and features PT tapered port threading for secure, leak-free pneumatic connections.

Where the Airtac SAI50 Standard Cylinder SAI50X150S Is Used
Clamping Fixtures
Provides reliable hold-down pressure for machining jigs, utilizing its 1374N thrust at 0.7 MPa to secure metal components during milling or drilling operations.
Package Diverting
Actuates sorting arms on packaging lines, where the 150mm stroke pushes cartons cleanly from the main conveyor belt into secondary routing lanes.
Vertical Lift Gates
Raises and lowers lightweight access gates or safety barriers in automated storage facilities, benefiting from the smooth adjustable air cushions at stroke ends.
Is the Airtac SAI50 Standard Cylinder SAI50X150S the Right Cylinder?
Choose this 50mm bore when a 32mm bore (402N at 0.5 MPa) lacks the necessary thrust, but an 80mm bore (2513N at 0.5 MPa) would be physically oversized. The 150mm stroke offers ample travel without requiring the extreme side-load management of longer extensions. For any application requiring the load to be securely held in place during a complete loss of air pressure, a standard SAI cylinder will drift; instead, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve.
This model ensures a direct replacement for any existing ISO 15552 mounting footprint. It uses a G1/4 port, accepts standard mounting accessories like FA flanges or TC trunnions, and requires the -S magnet option for position sensing.
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 SAI50X150S FAQ
At a 0.5 MPa operating pressure, this 50mm bore cylinder generates 982N of push force and 825N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374N.
Yes, the SAI50X150-S is dimensionally interchangeable per ISO 15552 standards. It serves as a direct replacement for other ISO 15552 profile cylinders, matching standard mounting interfaces and G1/4 port locations.
