Abstract
The tapered roller bearing with rotational speed detection unit has a tone wheel 30 which is externally fixed to an outward-facing cylindrical surface 28 formed on the outer peripheral surface of an inner ring 21 on the front face side, a casing 32 which is internally fixed to an inward-facing cylindrical surface 29 formed on the inner peripheral surface of an outer ring 23 on the back face side, a sensor 33 which is supported inside the casing 32 so as to be faced to the tone wheel 30, whereby there is no interference between the structural components during assembly of the tapered roller bearing, so that the assembly operation can be performed in a similar manner to that for a standard tapered roller bearing not having a rotational speed detection unit, and that miniaturization and lightening of the bearing as well as simplification of the assembly operation are possible.
