About the Airtac SAI125 Standard Air Cylinder SAI125X195
The AirTAC SAI125X195 is a double-acting ISO 15552 profile cylinder featuring a 125mm bore and a 195mm stroke. Because 195mm is not a standard production length, this specific configuration is manufactured as a made-to-order unit. It delivers robust linear motion, generating 6136 N of push force and 5734 N of pull force at 0.5 MPa. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that resists operational debris buildup.
This pneumatic actuator features a standard PT tapered port thread and a carbon steel piston rod for high tensile strength under heavy loads. While the standard configuration lacks a magnet, engineers can specify the -S option to integrate magnetic pistons for use with CMSE or DMSE series reed switches within the dual sensor grooves. For applications demanding multi-directional positioning, the SAID double-rod variant offers an alternative design.

Where the Airtac SAI125 Standard Air Cylinder SAI125X195 Is Used
Heavy-Duty Stamping
Provides the necessary 6136 N of thrust at 0.5 MPa to actuate medium-tonnage stamping and forming presses securely.
Pallet Diversion
Drives robust mechanical stops and diverter arms on high-mass conveyor lines handling industrial pallets.
Automated Clamping
Secures heavy fabricated components within machining fixtures, utilizing the full pull force to hold parts rigid.
Is the Airtac SAI125 Standard Air Cylinder SAI125X195 the Right Cylinder?
Selecting this 125mm bore actuator makes sense when your application requires upward of 6000 N of thrust at 0.5 MPa but stepping up to the 160mm bore (10053 N at 0.5 MPa) would be physically oversized and less efficient. The 195mm stroke is a custom length, so verify your machine envelope allows for the extended retraction distance. Because this is a custom stroke exceeding standard increments, expect a slightly longer lead time for production.
When integrating this actuator, note that the standard SAI does not secure a load if air pressure is lost; the piston will drift when the valve centers or pressure drops. If your machinery requires fail-safe holding, specify the SAIL lock variant or integrate an external pilot-operated check valve. Furthermore, while this unit is dimensionally interchangeable per ISO 15552 mounting interfaces, always confirm the exact mounting accessory footprint (such as FA flange or TC trunnion) and ensure you request the -S magnet if position feedback is required.
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 SAI125 Standard Air Cylinder SAI125X195 FAQ
At 0.5 MPa, this 125mm bore actuator generates 6136 N of push force and 5734 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 8590 N.
Yes, the SAI series is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 standard actuators. Ensure you match the mounting accessories and PT port threads to your existing infrastructure.
