About the Airtac SAI50 Standard Cylinder SAI50BX275S
The AirTAC SAI50X275-S is a double-acting ISO 15552 profile cylinder offering a 50mm bore and 275mm stroke. It provides 982N of push force at 0.5 MPa, making it well-suited for mid-range automation tasks requiring reliable linear motion over extended distances.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance in harsh environments. It includes a built-in magnet (-S) for use with CMSE and DMSE sensor switches, which mount directly into the dual-sided extruded barrel grooves. The fluid port utilizes a PT tapered thread standard.

Where the Airtac SAI50 Standard Cylinder SAI50BX275S Is Used
Package Diversion
Ideal for actuating diverter arms on packaging lines where the 275mm stroke reliably pushes cartons into secondary routing lanes.
Component Pressing
Delivers 982N of thrust at 0.5 MPa for pressing bearings or pins into housings without damaging surrounding machinery.
Pallet Handling
Moves lightweight pallets or product trays into position on assembly conveyors, utilizing the SUS304 rod to withstand washdowns.
Is the Airtac SAI50 Standard Cylinder SAI50BX275S the Right Cylinder?
If you need less force, stepping down to a 40mm bore yields 628N at 0.5 MPa; stepping up to a 63mm bore provides 1559N for heavier loads. Because this 275mm stroke exceeds the 300mm side-load threshold, use an external guide rail or a guided cylinder to prevent rod-bearing bending under lateral stress.
This unit functions as a direct replacement for any ISO 15552 cylinder with matching 50mm bore, 275mm stroke, and G1/4 port. Mounting accessories include LB, FA, or TC styles. Note that air cushions only decelerate the piston near stroke end; they do not hold loads. For position holding without live pressure, specify the SAIL or BSAI variant.
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.
