    摘要： An antifriction bearing (13,14) includes a fixed ring which comprises a steel containing up to about 10% of residual austenite. An alternator for vehicles includes a stator (12) mounted on a frame (10,11), a rotor (18) having its rotary shaft (15) rotatably supported by a pair or bearings (13,14) on the frame and a drive pulley (20) mounted on one end of the shaft projecting outward from the frame. The outer ring of at least the bearing (13) toward the pulley (20) comprises a steel containing up to about 10% of resi­dual austenite.
