About the Airtac SAI63 Standard Cylinder SAI63BX60
The AirTAC SAI63X60 is a double-acting profile cylinder built to ISO 15552 standards, delivering a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. Its 60 mm stroke provides a compact stroke length for mid-range actuation tasks. The extruded aluminum barrel design omits tie rods, offering a clean exterior that simplifies mounting and sensor placement.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or mildly chemically exposed environments. It utilizes PT tapered port threads and lacks a magnet for position sensing. For applications requiring end-of-stroke speed damping, the adjustable air cushions at both ends effectively decelerate the piston.

Where the Airtac SAI63 Standard Cylinder SAI63BX60 Is Used
Clamping Mechanisms
Provides reliable 1559 N clamping force at 0.5 MPa for securing mid-sized metal or composite workpieces during machining operations.
Product Diverters
Actuates diverting arms or pusher plates on packaging lines, utilizing its 60 mm stroke to reposition items between conveyor lanes.
Gate Control
Operates safety guards and access gates on automated cells, offering fast 30-800 mm/s cycling speeds with adjustable end cushions.
Is the Airtac SAI63 Standard Cylinder SAI63BX60 the Right Cylinder?
Selecting this bore size is ideal when a 50 mm bore (982 N push at 0.5 MPa) lacks sufficient thrust, but an 80 mm bore (2513 N push at 0.5 MPa) would be physically oversized. The 60 mm stroke offers a short, rigid extension, minimizing rod deflection under load. Because this is a non-magnet variant, you cannot use reed or solid-state sensors; if position feedback is needed, choose the SAI63X60-S model instead. To achieve a true ISO 15552 direct replacement, match the 63 mm bore, 60 mm stroke, G3/8 port, and mounting accessory type.
Remember that a standard SAI cylinder relies on live air pressure to maintain its position. If your application involves suspended loads that must resist drifting downward upon air loss or valve centering, you must integrate an external pilot-operated check valve or switch to the SAIL (air-released lock) variant.
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 SAI63BX60 FAQ
