The AirTAC SAI50 Standard Cylinder SAI50BX900S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 900mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI50X900-S is a double-acting ISO 15552 profile cylinder engineered for a 50mm bore and a 900mm stroke. It provides a robust push force of 982 N and a pull force of 825 N at 0.5 MPa, making it highly effective for long-travel material handling. The extended 900mm stroke is ideal for transferring components across wide machine spans.
This specific configuration includes a SUS304 stainless steel rod (material code B) for superior corrosion resistance in demanding environments. It is equipped with a magnet (-S) to seamlessly integrate CMSE or DMSE position sensors into the dual-side extruded aluminum barrel grooves. Fluid and air connections utilize PT tapered threads, ensuring a secure, leak-free pneumatic setup.

Pushes products or pallets across extended conveyor gaps during automated packaging and sorting operations.
Extends deep into storage racks to retrieve or deposit heavy bins in automated warehousing systems.
Actuates large-format panel feeding mechanisms where a long, smooth stroke and robust force are essential.
At 0.5 MPa, this 50mm bore generates 982 N of push force; if your application requires less force, stepping down to the 40mm bore yields 628 N, while moving up to the 63mm bore provides 1559 N. Because the 900mm stroke is substantial, the unsupported rod is highly susceptible to bending under side loads. To prevent premature wear on the rod bearing and seal, implement an external linear guide rail or utilize a fully guided cylinder for this length.
As a true ISO 15552 profile cylinder, this model serves as a direct replacement for any standard 50mm bore, 900mm stroke ISO 15552 unit. It features a G1/4 port, M16x1.5 rod thread, and 30mm adjustable air cushions at both ends. Remember that the standard SAI lacks a holding mechanism; if power or air is lost, the load will drift. For vertical loads requiring position retention without live pressure, select the SAIL locking variant or deploy an external pilot-operated check valve.
Quick checklist
The SAI50X900-S generates a push force of 982 N and a pull force of 825 N at 0.5 MPa. At a maximum operating pressure of 1.0 MPa, the theoretical push force reaches 1767 N.
Yes, this is a genuine AirTac ISO 15552 profile cylinder. Its standardized mounting interface and dimensions make it directly interchangeable with other ISO 15552 cylinders of the same 50mm bore and 900mm stroke.
