Sealing device with an encoder

摘要

Sealing device (1) with an encoder (7) which is suitable for reading the kinematic parameters of the functioning of a rolling contact bearing (3), the device (1) presenting a first shield (6) which is shrink-fit onto an external surface (42) of an inner race (4) of the contact rolling bearing (3) in order to support the said encoder (7), and a deformable blocking device (11), which is obtained on the first shield (6) and which is engaged in a circular groove (44) which is obtained on the external surface (42) in order to axially block the first shield (6) itself onto the inner race (4) while leaving free a contact portion (45) of the external surface (42) itself.
