About the Airtac SAI50 Standard Cylinder SAI50X190
The AirTAC SAI50X190 is a double-acting ISO 15552 profile barrel cylinder offering a push force of 982 N and a pull force of 825 N at 0.5 MPa. The 190 mm stroke provides ample travel for mid-range positioning tasks. Because it lacks a piston magnet, this configuration is optimized for purely mechanical actuation without sensor feedback.
This variant features a standard carbon steel piston rod and tapered PT port threads. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing you to easily add position detection later by switching to a magnet-equipped model if your automation requirements evolve.

Where the Airtac SAI50 Standard Cylinder SAI50X190 Is Used
Component Ejection
Provides the 982 N push force needed to eject molded parts from machining centers.
Package Diverting
Actuates diverter arms on packaging lines where a 190 mm stroke reliably redirects goods.
Clamp Actuation
Drives mid-sized clamping mechanisms in light assembly fixtures requiring robust force.
Is the Airtac SAI50 Standard Cylinder SAI50X190 the Right Cylinder?
Select this 50 mm bore when a 32 mm bore (402 N push at 0.5 MPa) is insufficient but an 80 mm bore (2513 N) would be physically oversized. The 190 mm stroke falls below the 300 mm threshold, so standard rod-bearing bending stresses are minimal. However, for applications experiencing heavy side loads, consider utilizing a guided cylinder or external rail to prevent premature seal wear.
As a true ISO 15552 cylinder, this unit is dimensionally interchangeable with other standard profile cylinders. When ordering, verify you need the PT port type, select your mounting accessory (such as an FA flange or TC trunnion), and remember that the standard SAI does not hold its load if air pressure is lost. For suspended loads requiring fail-safe holding, explore the SAIL air-released lock 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 SAI50X190 FAQ
At 0.5 MPa, this cylinder provides a push force of 982 N and a pull force of 825 N. If you operate at 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X190 adheres to strict ISO 15552 mounting dimensions. It is designed as a direct replacement for any standard ISO 15552 profile cylinder, provided you match the PT port configuration.
