A measuring bearing includes: a bearing (4); and a sensor unit (6) which is to sense the angle position of a ring (42) that can rotate on a fixing ring (44) of the bearing (4). The sensor unit senses parameters which indicate the revolutions per minute (RPM) of both an encoder element (62) fixated to the rotary ring (42) and the rotary ring (42), and includes a sensing element (640) fixated to the fixing ring (44). The sensing element (640) is mounted inside a casing fixated to the fixing ring (44). The casing (66) includes surrounding walls (666, 662) mounted on the fixing ring (44). The surrounding walls comprises: at least one snap part (666b) accommodated inside a concave groove (444) on the surface (442) of the fixing ring (44); and at least one blocking part (666a) adjacent to the horizontal surface (440) of the fixing ring (44). Each of the snap parts (666b) and each of the block parts (666a) are alternatively arranged around the central shaft (X6) of the casing (66). |
