Understanding Ball Bearings The 25x47x12 Metric Ball bearings are essential components in various mechanical systems, serving to reduce friction between moving parts and enhancing overall operational efficiency. One particularly common size in the world of mechanics is the metric ball bearing, identified by dimensions such as 25x47x12. This designation refers to the bearing's dimensions the inner diameter (ID) is 25 millimeters, the outer diameter (OD) is 47 millimeters, and the width (W) is 12 millimeters. Understanding the structure, applications, and benefits of this specific ball bearing size can greatly enhance its effective incorporation into mechanical designs. Structure of a Ball Bearing At its core, a ball bearing consists of several critical components inner race, outer race, balls (or rolling elements), and often a cage to maintain an even spacing between the balls. For the 25x47x12 ball bearing - Inner Race This is the component that fits onto the shaft, providing a surface for the balls to roll on as the shaft rotates. - Outer Race Positioned outside the inner race, the outer race is mounted to the housing or stationary part of the apparatus. - Balls These are the rolling elements that provide the actual motion and load support. Their spherical shape ensures minimal contact area, reducing friction. - Cage The cage serves to keep the balls equally spaced and allows for smooth operation of the bearing.
