About the Airtac SAI63 Standard Cylinder SAI63X65
The AirTAC SAI63X65 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 65 mm stroke is optimal for short-travel clamping and ejection tasks where space is restricted. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that resists debris accumulation.
This unit features a standard carbon steel piston rod and PT tapered port threads. For applications requiring position feedback, the barrel includes integrated sensor grooves on both sides, ready to accept CMSE or DMSE switches when paired with a magnet-equipped variant.

Where the Airtac SAI63 Standard Cylinder SAI63X65 Is Used
Short-Stroke Clamping
Provides reliable 1559 N clamping force at 0.5 MPa for securing metal workpieces during milling or drilling operations.
Package Diverter
Actuates a short 65 mm diverter arm to route medium-weight packages on a high-speed sorting line.
Part Ejection
Ejects molded or machined components from a fixture quickly, utilizing the 30-800 mm/s speed range for rapid cycling.
Is the Airtac SAI63 Standard Cylinder SAI63X65 the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore falls short of the 982 N push force at 0.5 MPa, but you want to avoid the bulk and higher air consumption of an 80 mm bore that generates 2513 N. The 65 mm stroke provides just enough extension for compact, localized movements without taking up excessive machine real estate.
Because this is a standard double-acting cylinder, it relies on continuous air pressure to hold position. If your mechanism must resist drift or hold a load safely during an emergency stop or pressure loss, consider the AirTAC SAIL locking variant or an external pilot-operated check valve. Mounting interchangeability follows the ISO 15552 standard, matching accessories like TC trunnions or FA flanges, with PT porting.
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 SAI63X65 FAQ
At a standard operating pressure of 0.5 MPa, the SAI63X65 provides 1559 N of push force and 1402 N of pull force. At the maximum rated pressure of 1.0 MPa, it can deliver a theoretical maximum force of 318 kgf.
Yes, the SAI63X65 is dimensionally interchangeable per ISO 15552. You can drop it in to replace other ISO 15552 profile cylinders with a 63 mm bore, matching your existing FA flange or TC trunnion mounts and PT port connections.
