Abstract
A method permits the use of a low-cost bearing and by which a bearing unit can be manufactured without requiring lathe turning or any special kind of compression, pressure application, etc., that experiences low loss and which assures high precision in the perpendicularity of the rotating shaft to be supported by the bearing. The process for manufacturing a bearing unit in which bearing that supports a rotating shaft in a freely rotatable manner is secured to mounting member. The process includes at least the following three steps: the first step for providing sizing bar in hole in bearing into which the rotating shaft is to be inserted; the second step for working an end portion of the bearing, thereby forming in an end portion of the hole a small-diameter portion that is equal in size to the outside diameter of the sizing bar; and the third step for securing the bearing to the mounting member.
