About the Airtac SAI100 Standard Air Cylinder SAI100X850S
The AirTAC SAI100X850-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and an 850mm stroke. It delivers a robust 5497 N of push force at 0.7 MPa, making it well-suited for heavy-duty actuation over long distances. This variant includes a magnetic piston for position sensing and uses a standard carbon steel rod for durability.
Beyond the standard spec sheet, this model features an extruded aluminum barrel with sensor grooves on both sides, allowing direct mounting of CMSE or DMSE switches. The piston seals are standard TPU, but Viton (H) options are available for high-temperature environments up to 70 C. As a genuine ISO 15552 profile cylinder, it provides a dimensionally interchangeable mounting interface for seamless integration into global machinery.

Where the Airtac SAI100 Standard Air Cylinder SAI100X850S Is Used
Heavy Material Handling
Ideal for pushing heavy pallets or transferring large components between conveyor lines where a long 850mm extension and 5497 N of force are required.
Large Press Ejection
Provides the long reach and robust push force necessary to eject finished metal or plastic parts from large stamping and molding presses.
Automated Assembly Line
Acts as a main actuator for positioning heavy structural frames or driving large indexing mechanisms in automated assembly facilities.
Is the Airtac SAI100 Standard Air Cylinder SAI100X850S the Right Cylinder?
This 100mm bore provides 5497 N of thrust at 0.7 MPa; stepping down to an 80mm bore yields 3518 N, while moving up to 125mm offers 8590 N for heavier payloads. Because this model has an 850mm stroke, the unsupported rod is highly susceptible to bending under side loads. To prevent premature seal wear and rod-bearing failure, use an external guide rail or a dedicated guided cylinder to handle any lateral forces.
This SAI100X850-S configuration includes a magnet for position sensing, a PT tapered port thread, and standard carbon steel rod material. If your machinery requires the load to stay fixed when air pressure is removed or exhausted, this standard cylinder will drift; you must use the SAIL locking variant or an external pilot-operated check valve for secure holding.
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.
