Abstract
An encoder wheel (1) for a roller bearing provided with a multipolar magnetised ring (5) presenting an axial thickness (S) which is radially variable in an inversely proportional way to a radius (R) of the ring (5) itself, and also provided with a metallic insert (6) for supporting the multipolar ring (5) itself; the metallic insert (6) presenting a curved annular wall (11), which axially delimits the multipolar ring (5), and presents a variable curvature to the variation of the thickness (S) of the multipolar ring (5).
