Abstract
A bearing housing (1) is fabricated with a bearing body (2) for holding a bearing (3); and a sealing member (4). The sealing member has a shaft insertion (6) for inserting a shaft into the bearing housing (1). The sealing member (4) is formed with a spherical outer surface (4a) which is movable in contact with the bearing housing body (2), and the sealing member (3) rests on the bearing (3) when installed in the bearing housing body (2). A circular opening (6) extends between a front-end circular opening (45) and a back-end circular opening (46), such that the back-end (42) is connected to the front-end (41) by a spherical structure (44).
