Starflex ALS AN

The Starflex has a simple construction of two hubs with a flexible element inside. There are three types of elements that differ in hardness and fit. The flexible element is a polyurethane elastomer and allows vibration damping and offset compensation.

Element hardness: 90 JIS A / 97 JIS A
Element as “tight fit” and “loose fit” available
RoHS compliant, Keyway optionally possible
1.2 Nm to 1050 Nm
Fits for Servo-, Stepper- und Standardmotors
