About the Airtac SAI50 Standard Cylinder SAI50AX185S
The AirTAC SAI50X185-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982N of push force at 0.5MPa. This 50mm bore and 185mm stroke configuration provides a standardized mounting interface, making it a direct replacement for other ISO 15552 cylinders. The extruded aluminum barrel design eliminates tie-rods for a clean exterior.
This specific variant includes a piston magnet for proximity sensing and uses a SUS420J2 stainless steel rod for enhanced corrosion resistance. It features tapered PT port threads and integrates adjustable air cushions at both ends to manage impact deceleration.

Where the Airtac SAI50 Standard Cylinder SAI50AX185S Is Used
Package Diverting
Provides the 982N force needed to push heavy cartons off a high-speed sorting conveyor belt.
Clamping Fixtures
Secures steel plates during machining operations, using the 185mm stroke to clear the work area.
Pallet Lifting
Raises lower-tier pallet stops in automated storage systems where a compact 50mm profile fits.
Is the Airtac SAI50 Standard Cylinder SAI50AX185S the Right Cylinder?
Selecting this 50mm bore is ideal when a 40mm bore (yielding 628N at 0.5MPa) lacks sufficient thrust, but an upgrade to a 63mm bore (1559N at 0.5MPa) would be physical overkill. The 185mm stroke offers extended travel for pushing or lifting tasks. Because the stroke is under 300mm, standard rod bearing bending loads are minimal, though external guides should still handle any heavy lateral payloads.
For applications requiring the piston to hold its position securely during a loss of air pressure, note that the standard SAI cylinder will drift. In those scenarios, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve. This model uses a PT port, G1/4 thread size, and pairs with FA/FB flange or LB foot mounting 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 SAI50AX185S FAQ
At an operating pressure of 0.5MPa, this 50mm bore cylinder generates 982N of push force and 825N of pull force. At 0.7MPa, the push force increases to 1374N.
Yes, the -S suffix indicates this model includes a piston magnet. You can directly mount CMSE or DMSE series sensor switches into the dual grooves on the aluminum barrel.
