About the Airtac SAI50 Standard Cylinder SAI50X290S
The AirTAC SAI50X290-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 290mm stroke. It generates a push force of 982 N at 0.5 MPa, making it well-suited for medium-duty industrial handling and positioning tasks.
This variant includes a standard carbon steel piston rod and a built-in magnet (-S) for direct compatibility with CMSE and DMSE reed switches. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting, and you can equip it with high-temperature Viton (H) seals for demanding thermal environments.

Where the Airtac SAI50 Standard Cylinder SAI50X290S Is Used
Automated Clamping
Provides reliable 982 N clamping force for holding medium-weight machined components securely during milling or drilling operations.
Package Diversion
Actuates diverter arms on processing lines to route heavy cartons or totes efficiently without requiring external pneumatic locks.
Vertical Lifting
Handles the vertical elevation of goods in pick-and-place modules, utilizing its 290mm stroke to transfer items between varying conveyor heights.
Is the Airtac SAI50 Standard Cylinder SAI50X290S the Right Cylinder?
If your application requires less thrust, the 40mm bore neighbor provides 628 N at 0.5 MPa, while stepping up to the 63mm bore yields 1559 N for heavier loads. Because this 290mm stroke approaches the longer end of the standard range, be mindful of rod-bearing bending under side loads; utilizing an external guide rail or a dedicated guided cylinder helps prevent premature wear.
This unit uses a PT tapered G1/4 port and can be mounted using FA/FB flanges or TC trunnion brackets. Remember that the adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the load. If pressure drops, the rod will drift, so specify a SAIL locking variant if position holding is mandatory.
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 SAI50X290S FAQ
At 0.5 MPa operating pressure, this 50mm bore cylinder delivers a push force of 982 N and a pull force of 825 N. It can reach up to 1374 N push force at 0.7 MPa.
Yes, the SAI50X290-S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders, provided the 50mm bore, 290mm stroke, and G1/4 port match your existing footprint.
