About the Airtac SAI63 Standard Cylinder SAI63BX75
The AirTAC SAI63X75 is a double-acting ISO 15552 profile cylinder offering 1559 N of push force at 0.5 MPa. Its 75 mm stroke is optimal for short-travel clamping and lifting tasks in tight machinery. As a genuine AirTAC component, it ensures reliable sealing and consistent pneumatic performance.
This specific unit is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threading and does not include a piston magnet, relying purely on mechanical cushioning for end-of-stroke deceleration.

Where the Airtac SAI63 Standard Cylinder SAI63BX75 Is Used
Short-Stroke Clamping
Delivers 1559 N of clamping force at 0.5 MPa to secure medium-sized workpieces during machining operations.
Ejector Mechanism
Provides rapid 75 mm ejection of finished parts from press lines using its 30-800 mm/s speed range.
Diversion Arm
Actuates compact routing arms on packaging conveyors where a stainless SUS304 rod resists environmental wear.
Is the Airtac SAI63 Standard Cylinder SAI63BX75 the Right Cylinder?
Stepping down to the 50 mm bore yields 982 N at 0.5 MPa, which is sufficient for lighter payloads, while moving up to the 80 mm bore provides 2513 N for heavier fixtures. Because this 75 mm stroke is short, side-load stress on the rod bearing is minimal. However, if the application requires holding a load vertically without continuous air pressure, note that a standard cylinder drifts; you should specify the SAIL lock or BSAI clamp-lock variant for fail-safe position holding. Ensure your ISO 15552 mounting interface matches the foot, flange, or trunnion accessories, and use PT threaded fittings for the G3/8 port.
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.
