                Bearings are fundamental components in mechanical systems, ensuring smooth rotation, reducing friction, and supporting radial and axial loads. While standard bearings are widely used for general applications, precision bearings are designed for high-accuracy and high-speed machinery. Selecting the correct bearing type is crucial for system performance, efficiency, and lifespan. 1.
