A bearing material (10) is produced by forming a Cu-Pb-system or Pb-bronze-system bearing alloy layer (8) on a steel plate (3) optionally plated with Cu, and forming a Pb alloy overlay (9) containing Zn on the bearing alloy layer so as to enhance corrosion resistance and conformability of the bearing alloy layer. A Cu-Zn alloy layer (11) of 0.5 to 10 mu m is present between the Cu matrix of the bearing alloy layer and the overlay. The Cu-Zn alloy layer prevents Sn and In in the overlay from diffusing into the Cu matrix of the bearing alloy layer. The multi-layered slide bearing material can be manufactured by forming the bearing alloy lining layer on the steel plate (3) optionally plated with Cu so as to obtain a bimetal plate, rolling the bimetal plate and a lead alloy plate for the overlay containing Zn to bond the plates in accumulative reduction of 8 to 48 %, and thereafter subjecting the plates to heat treatment at 170 to 250 DEG C. <IMAGE> |
