A workpiece feeding device includes a housing with a vertical support wall which has shaft mounting sleeves. First shafts extend horizontally and respectively through the sleeves. Two bearings are provided in two ends of each sleeve between the first shaft and the sleeve and are made of a powder-metallurgy process. Swing seats are mounted respectively to rear ends of the sleeves and have vertical seat walls which, in turn, have first holes for insertion of the sleeve and second holes for insertion of second shafts. Bushings project from the seat walls and have auxiliary seats which extend to the sleeves for connection therewith. As such, the machine can operate stably during the workpiece feeding operation.
