About the Airtac SAI50 Standard Cylinder SAI50BX350
The AirTAC SAI50X350 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 982 N and a pull force of 825 N at 0.5 MPa. Its extruded aluminum barrel eliminates tie-rods, providing a smooth exterior that drops directly into standard ISO 15552 mounting interfaces.
Configured with a SUS304 stainless steel piston rod (material code B), this 50 mm bore unit is highly resilient against moisture and corrosive environments. It utilizes PT tapered port threads for a mechanically sealed pneumatic connection, and because no magnet is specified, it operates without integrated position sensing.

Where the Airtac SAI50 Standard Cylinder SAI50BX350 Is Used
Product Diversion
Actuates diverter arms on packaging lines to route boxes efficiently using its 350 mm travel distance.
Stainless Welding Fixture
Clamps aluminum or steel parts in machining cells where the SUS304 rod prevents corrosion from coolant splashes.
Pallet Stopping
Extends to halt incoming pallets at a workstation, absorbing kinetic energy through its adjustable end cushions.
Is the Airtac SAI50 Standard Cylinder SAI50BX350 the Right Cylinder?
Choosing this 350 mm stroke means managing side loads carefully. At this extension length, the unsupported rod is susceptible to bending under lateral forces; utilizing an external guide rail or a dedicated guided cylinder will prevent premature rod-bearing wear. If your application requires less force, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, while upgrading to a 63 mm bore provides 1559 N.
This model uses G1/4 ports and accepts standard ISO 15552 mounting accessories like FA flanges or TC trunnions. Because it lacks a magnet, it cannot host CMSE or DMSE sensors; add the -S suffix if you require electronic position feedback. Note that standard air cushions only decelerate the piston near end-of-stroke and will not hold a load vertically if air pressure is lost.
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 SAI50BX350 FAQ
