About the Airtac SAI50 Standard Cylinder SAI50AX65
The AirTAC SAI50X65 is a double-acting ISO 15552 profile cylinder with a 50mm bore and 65mm stroke. It yields 982N of push force at 0.5 MPa, fitting medium-duty automation tasks. This specific 65mm stroke provides compact extension for clamping and lifting.
Configured with a SUS420J2 stainless steel rod (material code A), it resists corrosion in humid environments. The barrel features dual sensor grooves for CMSE or DMSE switches if a magnet is added later. Threaded PT ports ensure a tight, tapered pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50AX65 Is Used
Part Clamping
Provides 982N of push force at 0.5 MPa to hold medium workpieces securely during machining.
Package Diverter
The 65mm stroke offers quick, compact actuation for routing boxes on sorting lines.
Lift Station
Lifts light tooling or gates with reliable double-acting air power and adjustable cushions.
Is the Airtac SAI50 Standard Cylinder SAI50AX65 the Right Cylinder?
Select this 50mm bore when 32mm or 40mm cylinders lack sufficient thrust (40mm offers 628N at 0.5 MPa). The 65mm stroke is non-standard but ideal for short-travel clamps. For holding loads without air pressure, use a SAIL or BSAI variant, as the SAI50X65 drifts when pressure is lost.
It serves as a direct replacement for any ISO 15552 profile cylinder. Match your mounting accessory (LB, FA, TC) and note the PT port and G1/4 thread sizing. A magnet (-S) is required for reed 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.
