Deep Groove Ball Bearing
HCH deep groove ball bearings are the most representative rolling bearings, featuring a simple structure and ease of use. They primarily carry radial loads and can also accommodate certain axial loads. Manufactured from premium bearing steel (GCr15), they offer low friction, high limiting speed, and low noise. As the most widely used bearing type, they are extensively applied in electric motors, automobiles, home appliances, precision instruments, and general machinery.
