SFS MODELSERVO FLEX: A Wide Selection of Metal Plate SpringCouplings Made of SteelSERVO FLEXSFSThree types of couplings, either a high-rigidity type with one element, a high-fl exibility type with two elements using aspacer, or a floating shaft with configurable spacer length can be selected.A variety of methods are available for mounting on a shaft such as a friction lock compatible with a large diameter, a highprecisionfriction lock, a taper shaft-compatible method, and others.The pilot bore item has also been standardized, enabling methods such as the key/set screw method, shrink fi t-compatiblemethod, and others.PLATE SPRING OF IDEAL FORMHigh Rigidity, High FlexibilityAn ideal-shaped plate spring, designed basedon thorough analysis using the advancedfi nite element method (FEM), is applied for theelement.Three types of couplings, either a high-rigiditytype with one element, a high-flexibility typewith two elements using a spacer, or a fl oatingshaft with configurable spacer length can beselected.TORQUETHRUSTBENDINGRADIAL22COUPLING_E_22_41new.indd 22www.feyc.es9/15/10 4:22 PM
