THE SPLINE ADAPTER HAS BEEN DESIGNED TO FIT TIGHTLY TO ACHIEVE ACOMPRESSIVE PRELOAD WHICH EXTENDS THE OPERATING TORSIONAL RANGE OF THE NONMETALLIC SPLINEADAPTER. THE TIGHT FIT ALSO PROVIDES A RESISTANCE TO AXIAL MOVEMEN

POSITIVE RETENTION CAN BE ACHIEVED BY A VARIETY OF METHODS INCLUDINGLENGTHENING THE NONMETALLIC ADAPTER, INCORPORATION OF FLANGES IN THE ADAPTER DESIGN, AND THEUSE OF SNAP OR SPIRAL LOCK RINGS TO LIMIT THE AMOUNT OF AXIAL CLEARANCE.
