TOPLINE is constituted by deep groove ball bearings N.Dm is a speed factor where N is the speed rotation in rpm & Dm is the bearing average diameter
·maintenance-free operation over long periods of time is de- desired. ·the maximum speed of the bearing does not exceed the speed factor n x dm of the grease.
