About the Airtac SAI50 Standard Cylinder SAI50X35S
The AirTAC SAI50X35-S is a double-acting ISO 15552 profile cylinder engineered for compact actuation, delivering a robust 982 N of push force at 0.5 MPa. Its 35 mm stroke is ideal for short-travel clamping and positioning tasks where space is restricted. As a genuine AirTAC component, it ensures reliable performance across demanding cycles.
This variant includes a magnetic piston, allowing seamless integration with CMSE or DMSE reed switches via the dual sensor grooves on the extruded aluminum barrel. The standard carbon steel piston rod provides dependable tensile strength, while the tapered PT thread ensures a tight, leak-free pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50X35S Is Used
Short-Stroke Clamping
Provides high holding force in confined spaces for machining and welding fixtures.
Diversion Gates
Actuates package routing gates rapidly on high-speed packaging lines.
Part Ejection
Delivers quick, repetitive ejection of molded parts from machinery beds.
Is the Airtac SAI50 Standard Cylinder SAI50X35S the Right Cylinder?
If your application requires less force, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, whereas upgrading to a 63 mm bore provides 1559 N for heavier loads. The 35 mm stroke keeps the rod fully supported, minimizing side-load bending risks. Because this is a standard double-acting cylinder, it will drift if air pressure is lost; for fail-safe load holding, consider the SAIL or BSAI locking variants. Replacement is simplified by the ISO 15552 mounting interface, matching 50 mm bore, 35 mm stroke, G1/4 port, and compatible FA or LB mounting accessories.

- ✓ 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.
