About the Airtac SAI50 Standard Cylinder SAI50X105
The AirTAC SAI50X105 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Because 105 mm is not a standard factory increment, it is supplied as a non-standard stroke configuration, ensuring your exact travel requirement is met without compromise. Its extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration features a standard carbon steel piston rod and PT tapered port threads. The barrel incorporates dual sensor grooves, allowing you to easily mount CMSE or DMSE switches if a magnet is added later. For environments requiring higher thermal resistance, the standard TPU seals can be swapped for Viton (H) variants.

Where the Airtac SAI50 Standard Cylinder SAI50X105 Is Used
Component Clamping
Provides 982 N of clamping force at 0.5 MPa to hold medium-weight metal or plastic components securely during machining or drilling operations.
Package Diverting
The 105 mm stroke is optimal for actuating a diverter arm to push standardized totes or cartons smoothly between adjacent conveyor lanes.
Gate Control
Actuates access gates or machine safety doors, utilizing the adjustable air cushions to ensure the mechanism slows down gently before reaching the end of travel.
Is the Airtac SAI50 Standard Cylinder SAI50X105 the Right Cylinder?
Selecting this bore is ideal when your application requires around 1000 N of thrust at 0.5 MPa. If you need less force, stepping down to a 40 mm bore yields 628 N, while moving up to a 63 mm bore provides 1559 N. The adjustable air cushions at both stroke ends are strictly for decelerating the piston and do not hold a load in place.
Because this is a non-standard 105 mm stroke, it is built to order. When integrating it into your machine, remember that a plain double-acting cylinder will drift if air pressure is lost. If your system needs to maintain vertical position during an exhaust or power-down event, pair this cylinder with the SAIL air-released lock variant or an external pilot-operated check valve.
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 SAI50X105 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 SAI50X105 is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other standard ISO 15552 cylinders. It uses a G1/4 port and standard FA, FB, LB, or TC mounting accessories.
