ABSTRACT:
Protection device (1) for an encoder (2) in a rolling bearing (3) presenting an outer race (5) which is arranged in contact against a fixed support (6), the device being interposed between the encoder (2) itself and a reading sensor (17) which is supported by the support (6) itself, and being provided with: a fixing race (18) which is shrink fit onto the outer race (5) of the bearing (3) and frontally to a shoulder (15) of the support (6); a protection shield (19) which extends from the fixing race (18) towards an inner race (4) of the bearing (3) in a position which is frontal to both the encoder (2) and the sensor (17); and a sealing element (30), which is integral to the fixing race (18) and the shoulder (15) for the static waterproofing of the support (6).
