About the Airtac SAI63 Standard Cylinder SAI63X210
The AirTAC SAI63X210 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 210mm stroke. Because 210mm falls outside the standard increments, it is supplied as a made-to-order non-standard stroke. In this bore size, the cylinder generates a push force of 1559 N and a pull force of 1402 N at 0.5 MPa, making it well-suited for medium-duty industrial handling.
This unit utilizes a standard carbon steel piston rod and features an extruded aluminum barrel with sensor grooves on both sides for flexible switch mounting. If your assembly requires holding a load during a pressure drop, consider the SAIL variant which integrates an air-released lock, as the standard adjustable air cushions only decelerate the piston at stroke end.

Where the Airtac SAI63 Standard Cylinder SAI63X210 Is Used
Material Handling
Drives package diverters and mid-sized conveyor routing gates where a 210mm stroke provides precise actuation distance.
Assembly Line Ejection
Ejects machined parts from machining centers using 1559 N of push force at 0.5 MPa to clear the work area efficiently.
Clamping Fixtures
Secures workpieces during secondary machining operations, utilizing the 63mm bore's reliable clamping pressure.
Is the Airtac SAI63 Standard Cylinder SAI63X210 the Right Cylinder?
A 63mm bore provides 1559 N of push force at 0.5 MPa. If your application requires less force, stepping down to a 50mm bore yields 982 N. For heavier payloads, an 80mm bore offers 2513 N. Because this 210mm stroke is a non-standard length, always verify mounting accessory compatibility before finalizing your design.
As a genuine ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 cylinders without requiring bracket modifications. It uses a G3/8 PT port and supports standard mounts like FA flanges or TC trunnions. Note that -S is not specified, so this unit lacks a magnet for proximity sensors.
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.
