The present invention provides a bearing device. The bearing apparatus comprises a bushing. The bushing has an inner diameter IDs _HB, comprising a hollow body including a proximal end and a distal end portion that is opposite to each other. The bushing further includes a first bushing flange that extends from the proximal end of the body radially outwardly, and includes an axial extension portion extending from the distal end of the hollow body. Axial extending portion is deformable so as to form a second bushing flange extending radially outwardly from the distal end of the hollow body. Axially extending portion has an inner diameter of _{ID AE ≦ ID HB.}
