About the Airtac SAI63 Standard Cylinder SAI63X275S
The AirTAC SAI63X275-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559N of push force at 0.5MPa. Its 275mm stroke provides ample travel for mid-range positioning tasks. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
This variant includes a standard magnet for CMSE or DMSE sensor switches, which seat neatly into the dual side grooves on the barrel. It utilizes a carbon steel piston rod for robust strength and PT tapered port threads. For high-temperature environments up to 70C, the standard TPU seals can be swapped for Viton (H) alternatives.

Where the Airtac SAI63 Standard Cylinder SAI63X275S Is Used
Component Clamping
Secures medium-sized metal or plastic components during machining and assembly operations using its 1559N push force.
Package Diverting
Actuates diverting arms and sorting gates on packaging lines, utilizing the 275mm stroke to clear product lanes.
Material Ejection
Pushes molded or stamped parts out of press beds, relying on the carbon steel rod to withstand repetitive impact.
Is the Airtac SAI63 Standard Cylinder SAI63X275S the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm option upgrades your thrust from 982N to 1559N at 0.5MPa, while stepping up to the 80mm bore yields 2513N. Because the 275mm stroke exceeds 300mm, it is critical to manage side loads; long unsupported rods are prone to bending, so utilizing an external guide rail or a dedicated guided cylinder is recommended to prevent premature rod-bearing wear.
This model features a G3/8 PT port and an M16x1.5 rod thread. It functions as a dimensionally interchangeable replacement for any ISO 15552 cylinder matching these parameters. Remember that the standard adjustable air cushions only decelerate the piston near stroke end; if your application requires the load to be held mechanically without live air pressure, specify the SAIL or BSAI lock variant.
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.
