Rolling bearing with spring biased thrust ring, and method for measuring an axial clearance of a rolling bearing having a thrust ring

Abstract

A rolling bearing includes a first ring, a second ring, at least one row of axial rolling elements arranged between the first ring and the second ring, and at least one thrust ring axially interposed between the axial rolling elements and the first ring and delimiting a raceway for the axial rolling elements. At least one spring system axially biases the thrust ring against the axial rolling elements and includes a piston housed in a through-hole of the first ring and a spring element pressing the piston against the thrust ring. The piston includes a threaded hole accessible from outside the first ring.
