About the Airtac SAI50 Standard Cylinder SAI50BX325
The AirTAC SAI50X325 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 325 mm stroke provides the extended travel distance required for mid-range automation tasks. The extruded aluminum barrel omits tie-rods for a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 actuators.
This specific configuration incorporates a SUS304 stainless steel piston rod for superior corrosion resistance in wet or washdown environments. It features PT tapered port threads and lacks a standard magnet, meaning it is optimized for purely mechanical actuation without external sensor switching.

Where the Airtac SAI50 Standard Cylinder SAI50BX325 Is Used
Package Diverting
Extends 325 mm to push cartons between sorting lanes on a high-speed packaging line.
Parts Ejection
Uses 982 N of thrust to positively eject molded parts from a press area.
Gate Operation
Cycles a 325 mm stroke to open and close equipment safety gates during maintenance cycles.
Is the Airtac SAI50 Standard Cylinder SAI50BX325 the Right Cylinder?
Choose this 50 mm bore when a 40 mm bore (providing 628 N at 0.5 MPa) lacks sufficient thrust, but a 63 mm bore (delivering 1559 N) would be physically oversized. The 325 mm stroke is a standard option, falling well within the 1200 mm maximum limit for this bore size.
Because the stroke is 325 mm, the unsupported rod length is significant. Side loads can bend the rod and accelerate front bearing wear. For applications involving heavy offset loads, specify an external guide rail or select a guided cylinder to prevent mechanical binding. If your machinery must hold a load vertically when air pressure is removed, note that the standard adjustable air cushions only decelerate the piston at stroke end and do not function as a locking brake. For positive holding, specify the SAIL variant with an air-released lock or use 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.
