About the Airtac SAI50 Standard Cylinder SAI50X15S
The AirTAC SAI50X15-S is a double-acting ISO 15552 profile cylinder engineered for compact actuation. Delivering 982 N of push force at 0.5 MPa, this 50 mm bore unit is tailored for short-travel clamping and ejection tasks. The 15 mm stroke is a non-standard made-to-order dimension, ensuring exact fit for tight machinery envelopes.
This variant includes a standard magnet for CMSE or DMSE sensor integration along the dual extruded aluminum barrel grooves. The piston rod is constructed from durable carbon steel, and the standard TPU seals accommodate operating temperatures from -20 to +70 C.

Where the Airtac SAI50 Standard Cylinder SAI50X15S Is Used
Short-Stroke Clamping
Provides 982 N of clamping force at 0.5 MPa for holding heavy workpieces securely during machining operations.
Compact Ejection
The 15 mm non-standard stroke offers rapid, localized ejection of finished parts from constrained automated tooling.
Positioning Stops
Acts as a high-force mechanical stop in assembly lines, using the integrated magnet for precise end-of-stroke detection.
Is the Airtac SAI50 Standard Cylinder SAI50X15S the Right Cylinder?
Select this 50 mm bore when a 32 mm bore (402 N at 0.5 MPa) lacks the necessary push strength for high-force short strokes. Conversely, if your application requires less than 982 N, a smaller bore reduces air consumption. The 15 mm stroke is non-standard and made-to-order, ensuring a precise fit for specific compact machinery.
Because the SAI50X15-S is a double-acting cylinder, it relies on continuous air pressure to maintain its position; it will drift if pressure is lost. For drop-prevention, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. This model is dimensionally interchangeable per ISO 15552, featuring a G1/4 port, PT tapered threads, and standard mounting accessories like FA flanges or LB foot brackets.

- ✓ 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.
