About the Airtac SAI63 Standard Cylinder SAI63BX375
The AirTAC SAI63X375 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa and 1402 N of pull force. The 375 mm stroke is well-suited for mid-range linear actuation tasks requiring reliable extension and retraction.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance, alongside PT (tapered) port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE or DMSE switches if a magnet is added later.

Where the Airtac SAI63 Standard Cylinder SAI63BX375 Is Used
Automated Assembly Press
Provides the 1559 N force needed to seat bearings or pins during automated assembly line operations.
Material Diverting
The 375 mm stroke offers ample travel to actuate diverter arms and sort packages on moving conveyor belts.
Packaging Equipment
Drives forming and sealing mechanisms in packaging machinery where precise mid-stroke positioning is required.
Is the Airtac SAI63 Standard Cylinder SAI63BX375 the Right Cylinder?
If your application requires less force, stepping down to the 50 mm bore yields 982 N at 0.5 MPa, while moving up to the 80 mm bore provides 2513 N for heavier loads. Because this model features a 375 mm stroke, the unsupported rod is susceptible to bending under side loads; utilizing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature wear on the rod bearing.
As a genuine ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders, making it a seamless direct replacement. It utilizes a G3/8 port, an M16x1.5 rod thread, and adjustable air cushions at both ends. For any requirement to hold a load securely without live air pressure, a standard SAI will drift, so consider the SAIL lock or BSAI clamp-lock variant instead.
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.
