<p>Balls (3) provided between outer and inner race member rings (1 and 2) are made of high carbon chromium bearing steel. Depending on actual operating conditions, one or both of the outer and inner rings which require corrosion resistance and stable bonding strength are made of martensitic stainless steel with a hardness of HRC 58 or above and a eutectic carbide particle size of 10 mu m or below, thus improving the quietness and rust prevention properties of the bearing. The inner race member may be constituted by a shaft with a peripheral groove forming a ball race. <IMAGE></p> |
