About the Airtac SAI63 Standard Cylinder SAI63BX400
The AirTAC SAI63X400 is a double-acting ISO 15552 profile cylinder built for rigorous automation tasks. It delivers a robust 1559 N push force at 0.5 MPa, making it highly effective for mid-weight manipulation. This 400 mm stroke length is optimal for automated machinery requiring substantial linear travel.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in humid or washdown environments. It uses PT tapered port threads and lacks a standard magnet, but the extruded aluminum barrel includes dual sensor grooves if magnetic detection is added later.

Where the Airtac SAI63 Standard Cylinder SAI63BX400 Is Used
Material Forming
Provides the 1559 N push force at 0.5 MPa needed for medium-duty stamping, bending, and light press operations.
Package Diverting
The 400 mm stroke easily actuates large diverter arms and sorting gates across wide conveyor belts.
Machine Guarding
SUS304 rod material ensures reliable, corrosion-resistant operation for safety door actuation in washdown areas.
Is the Airtac SAI63 Standard Cylinder SAI63BX400 the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore falls short—its 982 N push at 0.5 MPa is insufficient for your load—or when an 80 mm bore (2513 N at 0.5 MPa) provides unnecessary excess force. At 400 mm stroke, the unsupported rod is prone to bending under side loads; utilize an external guide rail or a dedicated guided cylinder to prevent premature rod-bearing wear.
For applications requiring the piston to maintain its position after a pressure loss or valve centering, note that the standard adjustable air cushions only decelerate the rod at stroke end and do not lock the load. In these scenarios, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. As a true ISO 15552 profile cylinder, it offers direct dimensional interchangeability with other ISO 15552 cylinders.
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.
