About the Airtac SAI50 Standard Cylinder SAI50X290SH
The AirTAC SAI50X290-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 290mm stroke. It delivers a robust push force of 982 N at 0.5 MPa, making it well-suited for medium-duty positioning and clamping tasks.
Equipped with a magnetic piston (-S), this unit readily integrates with CMSE and DMSE sensor switches for precise end-of-stroke detection. It utilizes a high-temperature Viton (FKM) seal, expanding the operating envelope to handle hotter environments than standard TPU seals, and includes a durable carbon steel piston rod.

Where the Airtac SAI50 Standard Cylinder SAI50X290SH Is Used
Hot Environment Clamping
Secures workpieces on machining fixtures where ambient heat would degrade standard polyurethane seals, leveraging the Viton FKM high-temperature rating.
Extended Diverter Arm
Actuates a 290mm stroke diverter mechanism on packaging lines, using the magnetic piston to trigger CMSE sensors for precise timing.
Medium-Thrust Pressing
Provides consistent 982 N pressing force at 0.5 MPa for light assembly operations like bearing insertion or component seating.
Is the Airtac SAI50 Standard Cylinder SAI50X290SH the Right Cylinder?
Select this 50mm bore model when an application requires higher thrust than the 40mm bore variant (628 N at 0.5 MPa) but lacks the space or pneumatic capacity for the larger 63mm bore (1559 N at 0.5 MPa). The integrated G1/4 port ensures adequate airflow for its 30-800 mm/s speed range.
Because the 290mm stroke creates an extended rod overhang, external guide rails are recommended to prevent rod-bearing bending under heavy side loads. Note that the adjustable air cushions decelerate the piston at stroke ends but do not lock the load; if position holding is required upon air loss, utilize the SAIL or BSAI locking variants. Being dimensionally interchangeable per ISO 15552, it serves as a direct replacement for other ISO 15552 profile cylinders.
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.
