About the Airtac SAI63 Standard Cylinder SAI63X150
The AirTAC SAI63X150 is a double-acting ISO 15552 profile cylinder with a 63mm bore and 150mm stroke. It delivers a robust 1559N push force at 0.5MPa, making it well-suited for mid-weight industrial positioning tasks. The extruded aluminum barrel features dual sensor grooves, allowing direct mounting of CMSE or DMSE switches when paired with a magnet.
For demanding thermal environments, this model supports high-temperature Viton (H) seals instead of the standard TPU. The standard carbon steel piston rod provides excellent wear resistance for general automation, while the adjustable air cushions at both ends ensure smooth deceleration at operating speeds up to 800mm/s.

Where the Airtac SAI63 Standard Cylinder SAI63X150 Is Used
Automated Pressing
Provides reliable 1559N pressing force at 0.5MPa for assembling small mechanical components and bushings.
Product Diverting
Actuates heavy-duty diverter arms on packaging lines, utilizing the 150mm stroke to redirect products smoothly.
Clamping Fixtures
Secures workpieces during machining operations, taking advantage of the 2182N push force available at 0.7MPa.
Is the Airtac SAI63 Standard Cylinder SAI63X150 the Right Cylinder?
If your application requires less force, stepping down to a 50mm bore yields 982N push force at 0.5MPa, conserving compressed air. Conversely, moving up to an 80mm bore provides 2513N for heavier payloads. Because this is a double-acting cylinder, it relies entirely on live air pressure to move and hold its load; it will drift if pressure is lost. Use the SAIL variant if positive holding is required.
This model uses a PT G3/8 port and an M16x1.5 rod thread. Being a genuine ISO 15552 profile cylinder, it serves as a direct dimensional direct replacement for other standard cylinders. Ensure you specify the -S option if you need magnetic sensing capabilities.
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 SAI63 Standard Cylinder SAI63X150 FAQ
