Airtac SAI63 Standard Cylinder SAI63X75
The AirTAC Airtac SAI63 Standard Cylinder SAI63X75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 75mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAI63 Standard Cylinder SAI63X75
The AirTAC SAI63X75 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 75 mm stroke is optimal for short-travel clamping and indexing tasks. The extruded aluminum barrel eliminates tie rods, presenting a clean exterior that drops directly into existing ISO 15552 mounting interfaces.
This unit ships with standard carbon steel rod material and PT tapered port threads. Because it lacks a magnetic piston (-S option), it is optimized for pure pneumatic actuation rather than position sensing, though the barrel retains dual sensor grooves should you later need CMSE or DMSE switches.

Where the Airtac SAI63 Standard Cylinder SAI63X75 Is Used
Short-Stroke Clamping
Provides robust 1559 N holding force for securing heavy metal workpieces during CNC machining operations.
Package Diverting
Executes rapid 75 mm routing movements to sort heavy industrial cartons on high-speed packaging lines.
Press Ejection
Delivers reliable 1402 N pull force to extract formed parts from shallow stamping dies.
Is the Airtac SAI63 Standard Cylinder SAI63X75 the Right Cylinder?
At 0.5 MPa, this 63 mm bore generates 1559 N push and 1402 N pull force. If your application requires less force, stepping down to the 50 mm bore yields 982 N push, saving space and air consumption. If you need to move heavier loads, the 80 mm bore provides 2513 N push.
This cylinder uses adjustable air cushions at both ends to decelerate the piston, but it is not a locking device. If your machinery loses air pressure, the rod will drift and drop. For fail-safe load holding, select the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. To replace an existing actuator, match the 63 mm bore, 75 mm stroke, G3/8 PT ports, and your chosen mounting accessory like the FA flange or TC trunnion.
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.
