About the Airtac SAI50 Standard Cylinder SAI50X650
The AirTAC SAI50X650 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 650 mm stroke provides the extended travel needed for material handling and automated assembly tasks. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because it lacks a built-in magnet, position sensing requires external switches or a custom -S variant. For environments requiring high-temperature endurance, the standard TPU seals can be swapped for Viton (H) or NBR (N) options.

Where the Airtac SAI50 Standard Cylinder SAI50X650 Is Used
Long-Stroke Diversion
Pushes packages or product lanes across a 650 mm gap on automated conveyor lines using 982 N of thrust at 0.5 MPa.
Extended Reach Handling
Actuates gripper assemblies or end-effectors requiring significant horizontal reach in CNC loading and unloading stations.
Pallet Positioning
Indexes empty pallets or intermediate bulk containers into precise staging zones before they enter robotic wrapping cells.
Is the Airtac SAI50 Standard Cylinder SAI50X650 the Right Cylinder?
Selecting this 50 mm bore is ideal when a 40 mm bore (628 N at 0.5 MPa) lacks the necessary thrust, but a 63 mm bore (1559 N at 0.5 MPa) would be physically oversized. The 650 mm stroke demands careful attention to side loading. Long unsupported rods are prone to bending under lateral forces, so utilizing an external guide rail or a guided cylinder module is strongly recommended to prevent premature rod-bearing wear.
As a standard double-acting cylinder, this model relies on continuous air pressure to maintain its position. If air is exhausted or the valve centers, the piston will drift. For applications that must hold a load safely without live pressure, integrate an external pilot-operated check valve or specify the SAIL (air-released lock) variant. Replacement matches require a 50 mm bore, 650 mm stroke, G1/4 port, and appropriate FA, LB, or TC mounting accessories.
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 SAI50 Standard Cylinder SAI50X650 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X650 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders with a 50 mm bore, 650 mm stroke, and G1/4 port, provided your mounting accessories match.
