About the Airtac SAI63 Standard Cylinder SAI63AX260
The AirTAC SAI63X260 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 260 mm stroke provides the extended travel needed for mid-range positioning tasks. As a standardized extruded aluminum barrel cylinder, it offers a true drop-in replacement for other ISO 15552 actuators without requiring custom mounting plates.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not supported unless a -S variant is specified. The adjustable air cushions at both ends ensure smooth deceleration of moving loads.

Where the Airtac SAI63 Standard Cylinder SAI63AX260 Is Used
Mid-Force Clamping
Provides 1559 N of push force at 0.5 MPa for securing heavy metal workpieces during CNC machining or welding operations.
Package Diverting
The 260 mm stroke extends fully to reroute large cartons or pallets on automated material handling lines.
Press Ejection
Uses the 1402 N pull force at 0.5 MPa to reliably extract finished parts from stamping presses.
Is the Airtac SAI63 Standard Cylinder SAI63AX260 the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm version increases your 0.5 MPa push thrust from 982 N to 1559 N, while stepping up to the 80 mm bore yields 2513 N. The 260 mm stroke is well within the 1500 mm standard maximum, making it highly versatile. Because the stroke is 260 mm, designers should verify that side loads are minimized; for applications with heavy off-center loads, consider a guided cylinder or external rail system to prevent rod bearing wear.
This model uses PT tapered ports and a G3/8 thread size. If your machine requires fail-safe load holding when air pressure is removed, note that the standard adjustable cushion only decelerates the piston and does not brake or lock it. For those specific safety requirements, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of the standard SAI.
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 SAI63AX260 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X260 is built to the ISO 15552 profile standard, making its mounting dimensions interchangeable with other ISO 15552 cylinders. Always confirm your port thread (PT G3/8) and accessory mounting match.
