About the Airtac SAI63 Standard Cylinder SAI63X65S
The AirTAC SAI63X65-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 65mm stroke. It provides a push force of 1559 N at 0.5 MPa, making it well suited for compact mid-range automation tasks. The extruded aluminum barrel omits tie rods to provide a clean exterior.
This variant includes a magnet for use with CMSE and DMSE sensor switches. The standard carbon steel piston rod offers durable service, and the PT tapered port threads ensure a tight pneumatic connection at the G3/8 inlet.

Where the Airtac SAI63 Standard Cylinder SAI63X65S Is Used
Clamping Mechanisms
Provides 1559 N of push force at 0.5 MPa to secure heavy metal workpieces during machining operations.
Package Diverting
Uses the 65mm stroke to rapidly push mid-weight cartons off a main conveyor belt into a sorting lane.
Material Ejection
Delivers rapid ejection of molded parts from production tooling within a compact machine footprint.
Is the Airtac SAI63 Standard Cylinder SAI63X65S the Right Cylinder?
Choose this 63mm bore when 50mm falls short at 982 N push force, or step down from 80mm which delivers 2513 N. The 65mm stroke is ideal for tight spaces. For applications requiring position holding without live air pressure, select the SAIL lock or BSAI clamp-lock variant instead of relying on the standard air cushion. To mount this cylinder, use ISO 15552 accessories like FA flange or TC trunnion brackets.
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.
