About the Airtac SAI50 Standard Cylinder SAI50X195S
The AirTAC SAI50X195-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 195mm stroke. It delivers a push force of 982 N at 0.5 MPa, making it well-suited for medium-duty handling and processing tasks. The extruded aluminum barrel design omits tie rods for a clean exterior.
This variant includes a built-in magnet (-S) enabling seamless integration with CMSE and DMSE series sensor switches via the dual lateral grooves. It utilizes standard carbon steel piston rod material and PT tapered port threads, while offering NBR or high-temperature Viton (H) seal options to match diverse environmental demands.

Where the Airtac SAI50 Standard Cylinder SAI50X195S Is Used
Material Diverting
Ideal for actuating diverter arms on packaging lines where 982 N of push force reliably redirects medium-weight cartons.
Press Fitting
Supplies consistent downward pressure for assembling small bearings or pins into housings without requiring a full hydraulic press.
Pallet Handling
Drives lifting forks and stopper gates on automated storage retrieval systems, utilizing the integrated magnet for precise end-position sensing.
Is the Airtac SAI50 Standard Cylinder SAI50X195S the Right Cylinder?
Providing 982 N of thrust at 0.5 MPa, this bore size is an ideal middle ground; step down to a 40mm bore for lighter 628 N tasks, or up to a 63mm bore if your application requires 1559 N. The 195mm stroke is well within the 1200mm standard limit and avoids the excessive rod-bearing bending risks seen in longer 300mm+ strokes.
As a dimensionally interchangeable ISO 15552 unit, it serves as a direct replacement for other profile cylinders matching the 50mm bore, 195mm stroke, PT G1/4 port, and standard mounting accessories like FA flange or TC trunnion. Note that the adjustable air cushions only decelerate the piston at end-of-stroke; they do not hold loads. If pressure drops, the rod drifts, so utilize an external pilot-operated check valve or the SAIL lock variant for position holding.
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 SAI50X195S FAQ
At a 0.5 MPa operating pressure, this 50mm bore cylinder provides a push force of 982 N and a pull force of 825 N. If pressure is increased to 0.7 MPa, the push force reaches 1374 N.
Yes. Because it is built to the ISO 15552 standard, its mounting dimensions, port locations, and rod thread sizes are fully interchangeable with other ISO 15552 profile cylinders of the same bore size.
