About the Airtac SAI50 Standard Cylinder SAI50BX50S
The AirTAC SAI50X50-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 50mm stroke. It delivers a robust push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for compact, high-force clamping and lifting operations. The extruded aluminum barrel design eliminates tie rods while maintaining strict dimensional interchangeability per ISO 15552.
Configured with a SUS304 stainless steel rod, this model provides superior corrosion resistance for humid or washdown environments. The integrated -S magnet allows seamless pairing with CMSE or DMSE sensor switches fitted into the dual side grooves. Fluid supply is routed through a PT tapered G1/4 port, and the unit includes adjustable air cushions at both ends to manage impact deceleration.

Where the Airtac SAI50 Standard Cylinder SAI50BX50S Is Used
Compact Part Clamping
Generates 982 N of push force at 0.5 MPa to hold rigid workpieces securely during machining or drilling operations.
Package Diverting
The 50mm stroke extends rapidly at up to 800 mm/s to push cartons between adjacent conveyor lines without excessive cycle time.
Washdown Ejection
The SUS304 stainless steel rod resists moisture and corrosion, making it ideal for ejecting parts in food or chemical processing lines.
Is the Airtac SAI50 Standard Cylinder SAI50BX50S the Right Cylinder?
Choose this 50mm bore when 40mm cylinders lack thrust, stepping up from 628 N to 982 N at 0.5 MPa. If your application requires less force, dropping to a 40mm bore saves space. For this short 50mm stroke, side-load stress on the rod bearing is minimal, so standard mounting accessories like FA flanges or LB foot brackets are highly effective.
Because it is a standard double-acting cylinder, the piston will drift if air pressure is lost. If your machine needs to secure a suspended load during an emergency air cut-off, specify the SAIL variant with an air-released lock or use an external rod lock. To replace this unit, match the 50mm bore, 50mm stroke, G1/4 port, and the -S magnet requirement.
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 SAI50BX50S FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982 N of push force and 825 N of pull force. If operating at 0.7 MPa, the push force increases to 1374 N.
The -S suffix indicates a magnetic piston designed for AirTAC CMSE or DMSE series switches, which slide directly into the barrel's dual sensor grooves for precise position detection.
