About the Airtac SAI50 Standard Cylinder SAI50X300
The AirTAC SAI50X300 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 300 mm stroke provides the extended travel needed for material handling and automated clamping tasks. The extruded aluminum barrel eliminates tie-rods, resulting in a cleaner profile that drops directly into standardized ISO 15552 mounting footprints.
This configuration utilizes a standard carbon steel piston rod and PT tapered port threads. For environments requiring position feedback, the barrel features dual sensor grooves compatible with CMSE or DMSE switches when a magnet is specified. If your process involves high temperatures, you can upgrade the standard TPU seals to Viton (H) for enhanced thermal resistance.

Where the Airtac SAI50 Standard Cylinder SAI50X300 Is Used
Package Diversion
Actuates routing gates on packaging lines, using the 300 mm stroke to push cartons cleanly onto adjacent conveyors.
Workpiece Clamping
Secures mid-sized aluminum or steel castings during CNC machining, leveraging 982 N of thrust at 0.5 MPa for rigid holding.
Pallet Stopper Arms
Functions as an extended stop arm on roller conveyors to halt incoming pallets at a designated wrapping or scanning station.
Is the Airtac SAI50 Standard Cylinder SAI50X300 the Right Cylinder?
Select this 50 mm bore when an application demands more thrust than the 40 mm version (628 N at 0.5 MPa) but lacks the physical space for a 63 mm unit. At 300 mm of travel, the extended rod is susceptible to bending under side loads; utilize an external guide rail or a dedicated guided cylinder to prevent premature rod-bearing wear.
To guarantee a seamless ISO 15552 replacement, verify the 50 mm bore, 300 mm stroke, G1/4 PT porting, and your required mounting accessory (such as an FA flange or TC trunnion). Note that this standard cylinder relies on air pressure to maintain its position; if the air supply drops, the load will drift. For dead-end holding without live pressure, consider the SAIL variant with an air-released lock.
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 SAI50X300 FAQ
At a 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X300 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders, provided your porting, stroke, and mounting accessories match.
