About the Airtac SAI50 Standard Cylinder SAI50X190S
The AirTAC SAI50X190-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Featuring a 50 mm bore and a 190 mm stroke, this unit occupies a versatile mid-range capacity suited for general automation. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes a magnet for position sensing, allowing seamless integration with CMSE or DMSE reed switches along the dual sensor grooves. It is built with a standard carbon steel piston rod and utilizes PT tapered port threads. For environments requiring elevated thermal resistance, the standard TPU seals can be swapped for Viton (H) or NBR (N) alternatives.

Where the Airtac SAI50 Standard Cylinder SAI50X190S Is Used
Package Diverting
Actuates routing gates on packaging lines where 982 N of push force easily deflects moderate-weight cartons.
Clamping Fixtures
Secures workpieces during machining operations, using the integrated magnet to confirm clamp engagement.
Vertical Lifting
Raises lightweight pallets or totes through 190 mm of travel, relying on adjustable cushions to prevent end-impact.
Is the Airtac SAI50 Standard Cylinder SAI50X190S the Right Cylinder?
Selecting this 50 mm bore makes sense when a 40 mm bore (providing 628 N at 0.5 MPa) lacks sufficient thrust, but a 63 mm bore (1559 N) would be physical overkill. The 190 mm stroke offers ample extension for ejecting or lifting parts without the space demands of a 300 mm-plus travel. Because the stroke remains under 300 mm, rod-bearing bending stress is minimal, though external guides should still govern any heavy off-center loads.
If your mechanism must maintain its position after air pressure is removed, note that the adjustable air cushions only decelerate the piston at end-of-stroke and will not hold a load. In such cases, specify the SAIL variant with an air-released lock, or integrate an external pilot-operated check valve. For a direct replacement, match the 50 mm bore, 190 mm stroke, G1/4 port, and choose appropriate FA flange or LB foot accessories.
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 SAI50X190S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X190-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the 50 mm bore and 190 mm stroke specifications, using the G1/4 port.
