About the Airtac SAI50 Standard Cylinder SAI50X375S
The AirTAC SAI50X375-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 375 mm stroke provides the extended travel needed for mid-range material handling and automated positioning tasks. As a genuine AirTAC component, it ensures reliable pneumatic performance.
This model features an integrated magnet (-S) that enables seamless position detection using CMSE or DMSE series switches housed within the dual sensor grooves on the extruded aluminum barrel. It comes standard with a carbon steel piston rod and utilizes adjustable air cushions at both ends to decelerate the payload smoothly.

Where the Airtac SAI50 Standard Cylinder SAI50X375S Is Used
Package Diverting
Extends 375 mm to push medium-weight cartons off a main conveyor line onto secondary packaging lanes with precise timing.
Component Staging
Moves aluminum workpieces into the staging area of a CNC cell, using the integrated magnet to confirm part placement.
Pallet Loading
Actuates a lifting mechanism to position flat-packed goods onto wooden pallets prior to stretch wrapping.
Is the Airtac SAI50 Standard Cylinder SAI50X375S the Right Cylinder?
Select this 50 mm bore unit when a 40 mm bore falls short of the required 628 N push force at 0.5 MPa, but you want to avoid the larger envelope of a 63 mm cylinder. Because this 375 mm stroke creates an extended rod, external guides or a guided cylinder carriage are strongly recommended to prevent rod-bearing bending under side loads.
This profile cylinder is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 cylinders with a 50 mm bore, 375 mm stroke, PT tapered ports, and standard mounting accessories like FA flanges or TC trunnions. Note that standard air cushions only decelerate the piston; they do not hold the load. If the application requires position holding without live air pressure, consider the SAIL locking variant or an external rod lock.
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 SAI50X375S FAQ
At an operating pressure of 0.5 MPa, this double-acting cylinder generates 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X375-S is built to ISO 15552 dimensional standards, making it a direct replacement for any standard 50 mm bore profile cylinder with matching stroke and PT port dimensions.
