About the Airtac SAI63 Standard Cylinder SAI63BX280
The AirTAC SAI63X280 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 280mm stroke. It generates 1559N of push force at 0.5 MPa, making it well-suited for mid-range industrial actuation where consistent thrust is required over a moderately long travel distance.
This specific configuration incorporates a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel integrates dual sensor grooves, allowing direct mounting of CMSE or DMSE switches when a magnet is required for position feedback.

Where the Airtac SAI63 Standard Cylinder SAI63BX280 Is Used
Mid-Range Assembly Press
Provides reliable 1559N thrust at 0.5 MPa for pressing bearings or pins into housings on automated machining lines.
Pallet Diverting
The 280mm stroke offers sufficient travel to extend and divert heavy pallets across conveyor belts in material handling systems.
Packaging Flap Folding
Delivers the precise linear motion needed to fold and seal large cardboard flaps on continuous packaging equipment.
Is the Airtac SAI63 Standard Cylinder SAI63BX280 the Right Cylinder?
If your application requires less force, stepping down to the 50mm bore yields 982N at 0.5 MPa, while moving up to the 80mm bore provides 2513N for heavier loads. Because this 280mm stroke creates a long unsupported rod extension, external guides or a guided cylinder carriage are strongly recommended to prevent rod-bearing bending under side loads.
This model uses a G3/8 port and M16x1.5 rod thread. It is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other standard profile cylinders. Note that the adjustable air cushions only decelerate the piston at end-of-stroke; they do not hold a load. If power drops, use an external rod lock or the SAIL variant to prevent drifting.
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.
