Bearing and its maintenance
The surface on which the rolling elements roll is referred to as the ‘raceway surface’. The load placed on the bearings is supported by this contact
housing. These are made of high-grade carbon chromium steel with a high degree of cleanliness and surface finish. Both rings are made of different sizes and shapes depending upon the type of bearing. Both rings have a groove through out the circumference compatible to the size and type of rolling element. Each ring is given heat treatment so as to possess hardness between 59 and 65 HRC.
