About the Airtac SAI50 Standard Cylinder SAI50X290
The AirTAC SAI50X290 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 290mm stroke. It generates a push force of 982 N at 0.5 MPa, making it well-suited for medium-duty industrial handling tasks that require a longer travel range.
This model features a standard carbon steel piston rod and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches if position feedback is required later.

Where the Airtac SAI50 Standard Cylinder SAI50X290 Is Used
Material Diverting
Ideal for actuating diverter arms on conveyor lines where the 982 N force class easily redirects medium-weight packages over a 290mm reach.
Assembly Pressing
Provides a consistent 290mm stroke for pressing small bearings or pins into housings on automated assembly machinery.
Vertical Lifting
Suitable for lifting workpieces vertically, provided an external guide is used to prevent rod bending during the extended 290mm travel.
Is the Airtac SAI50 Standard Cylinder SAI50X290 the Right Cylinder?
If an application requires slightly less force, stepping down to a 40mm bore yields 628 N at 0.5 MPa, while moving up to a 63mm bore provides 1559 N for heavier loads. Because this 290mm stroke approaches the mid-range of the standard capacity, it is crucial to manage side loads. Unsupported rods can bend under lateral stress, so utilizing an external guide rail or a guided cylinder mechanism is strongly recommended for stable operation.
As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders, serving as a direct replacement. It uses a G1/4 port, an M16x1.5 rod thread, and can be paired with FA or LB mounting accessories. Note that a standard SAI does not hold its load when air pressure is lost; for fail-safe holding, consider the SAIL variant with an air-released lock.
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.
