About the Airtac SAI63 Standard Cylinder SAI63X300S
The AirTAC SAI63X300-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 300mm stroke. It delivers a robust 1559N push force at 0.5 MPa, making it well-suited for moderate-to-heavy material handling tasks requiring extended reach. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists debris accumulation.
Configured with a magnetic piston for position detection, this unit seamlessly integrates CMSE or DMSE series sensor switches along the dual side grooves. The standard carbon steel piston rod offers dependable wear resistance, while the adjustable air cushions at both ends ensure smooth deceleration of dynamic loads across the 30-800 mm/s speed range.

Where the Airtac SAI63 Standard Cylinder SAI63X300S Is Used
Extended Reach Diverting
Ideal for actuating diverter arms on wide conveyor systems where the 300mm stroke reliably pushes cartons between sorting lanes.
Pallet Push-Off Mechanism
Provides the necessary 1559N of push force at 0.5 MPa to slide heavy packaged goods off accumulation roller conveyors.
Long-Stroke Part Ejection
Used in CNC machining cells to eject finished components clear of the work envelope, leveraging the full 300mm travel distance.
Is the Airtac SAI63 Standard Cylinder SAI63X300S the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm option upgrades your thrust from 982N to 1559N at 0.5 MPa, whereas stepping up to an 80mm bore yields 2513N for heavier rigging. Because this model features a 300mm stroke, the extended rod is susceptible to bending under lateral loads; for offset or side-load applications, utilize an external guide rail or a guided cylinder to prevent premature rod-bearing wear.
This genuine AirTAC component ensures dimensionally interchangeable mounting per ISO 15552 standards. To retrofit, verify the 300mm stroke, 63mm bore, G3/8 PT tapered port, and compatible mounting accessories like FA flanges or TC trunnions. The integrated -S magnet enables precise end-of-stroke signaling without external mechanical stops.

- ✓ 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 SAI63 Standard Cylinder SAI63X300S FAQ
At 0.5 MPa operating pressure, this 63mm bore cylinder provides a push force of 1559N and a pull force of 1402N. At 0.7 MPa, the push force increases to 2182N.
Yes, the SAI63X300-S is dimensionally interchangeable per ISO 15552 standards. You can drop it in to replace other ISO 15552 profile cylinders of the same bore and stroke, provided your mounting interface and G3/8 port match.
