About the Airtac SAI50 Standard Cylinder SAI50BX375S
The AirTAC SAI50X375-S is a double-acting ISO 15552 profile cylinder engineered for precise linear motion. Delivering a push force of 982 N and a pull force of 825 N at 0.5 MPa, this 50 mm bore unit is tailored for mid-range actuation tasks. The 375 mm stroke provides ample extension for packaging and material transfer operations.
This specific configuration includes a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in humid or washdown environments. Equipped with a magnetic piston (-S), it supports direct mounting of CMSE or DMSE reed switches along the dual sensor grooves machined into the extruded aluminum barrel. It features PT tapered port threads for a robust pneumatic seal.

Where the Airtac SAI50 Standard Cylinder SAI50BX375S Is Used
Product Diverting
Ideal for pushing packages on a conveyor line, utilizing the 375 mm stroke to divert items into sorting lanes with reliable 982 N of thrust.
Carton Erection
Provides the long linear reach required to pull and form corrugated cartons flat-bottom-first before sealing operations begin.
Gate Control
Actuates safety gates or machine access doors, where the SUS304 rod material withstands occasional washdowns or humid plant atmospheres.
Is the Airtac SAI50 Standard Cylinder SAI50BX375S the Right Cylinder?
When evaluating this 50 mm bore option, consider stepping down to a 40 mm cylinder if your application only requires 628 N of push force at 0.5 MPa, which can optimize space and air consumption. Conversely, if the load demands greater thrust, upgrading to the 63 mm bore yields 1559 N at the same pressure. Because the 375 mm stroke creates a long unsupported rod extension, applying side loads can cause rod-bearing bending and premature wear; utilizing an external guide rail or a twin-rod guided cylinder is strongly recommended to maintain smooth travel.
As a genuine AirTAC component, this profile cylinder offers a direct replacement for any ISO 15552 standard assembly. To ensure seamless interchangeability, verify your mounting hardware (such as an FA foot bracket or TC trunnion) matches the 50 mm ISO footprint, and connect your air supply using the PT G1/4 port. The integrated adjustable air cushions at both ends decelerate the piston to prevent end-cap impact, but note this is not a locking mechanism; if the machine loses air pressure, the rod will drift. For fail-safe load holding, integrate an external pilot-operated check valve or specify an SAIL locking 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.
Airtac SAI50 Standard Cylinder SAI50BX375S FAQ
At an operating pressure of 0.5 MPa, this 50 mm bore cylinder generates a push force of 982 N and a pull force of 825 N. If you increase the pressure to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X375-S is dimensionally interchangeable with any standard ISO 15552 profile cylinder. You can swap it directly by matching the 50 mm bore, 375 mm stroke, and G1/4 port size.
