About the Airtac SAI50 Standard Cylinder SAI50X15
The AirTAC SAI50X15 is a double-acting ISO 15552 profile cylinder engineered for compact actuation. Delivering a push force of 982 N at 0.5 MPa, this 50 mm bore unit provides robust thrust within a highly constrained 15 mm stroke envelope.
This configuration utilizes a standard carbon steel piston rod and PT tapered port threads. The extruded aluminum barrel incorporates dual sensor grooves, allowing direct mounting of CMSE or DMSE switches when a magnet is specified for position feedback.

Where the Airtac SAI50 Standard Cylinder SAI50X15 Is Used
Short-Stroke Clamping
Ideal for securing workpieces in machining fixtures where a 982 N clamping force is needed over a very brief 15 mm travel distance.
Product Ejection
Provides a rapid, compact ejection mechanism on packaging lines, using its 825 N pull force to push items off a conveyor belt quickly.
Gate Diverter
Actuates short diverter gates on material handling systems, offering precise 15 mm movements to route small components downstream.
Is the Airtac SAI50 Standard Cylinder SAI50X15 the Right Cylinder?
Choose this 50 mm bore when an application requires greater thrust than the 40 mm variant (628 N at 0.5 MPa) but has strict axial length limits. The 15 mm stroke is optimal for short clamping or ejecting tasks. Because the stroke is brief, rod-bearing bending is negligible, but ensure the PT port threads match your existing fittings.
For interchangeability, this profile cylinder matches standard ISO 15552 mounting dimensions. Select appropriate FA or LB accessories. Note that standard double-acting cylinders drift if air pressure is lost; use a SAIL variant if the mechanism requires pneumatic locking to hold a load safely.
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 SAI50X15 FAQ
