摘要: A roller bearing (21) includes a plurality of needle rollers (23), a cage (24) that retains the rollers (23), and an outer ring (22) that has a rolling surface on which the rollers roll and is split in the circumferential direction. The cage (24) includes split sections (32a), (32b) at which the cage can be split in the circumferential direction. The cage (24) is of a roller riding type or an inner land riding type.

摘要: A preload inspection method for a bearing device for a vehicle wheel comprises: a first bearing preload value calculation step for calculating a first bearing preload value; a first rotating torque measurement step for measuring a first rotating torque; a caulking step for swaging the small-diameter stepped part to the inner ring; a second bearing preload value calculation step for calculating a second bearing preload value; a second rotational torque measurement step for measuring a second rotational torque; a third bearing preload value calculation step for calculating a third bearing preload value by adding, to the first bearing preload value, a preload change amount based on a differential torque between the first rotating torque and the second rotating torque; and a determination step for determining the suitability of the preload from the second bearing preload value and the third bearing preload value.
