1. Industrial machinery These bearings are commonly used in conveyor systems, machine tools, and presses. 1. Sealed Design The Ball Bearing 6004 2RS features a sealed design, which prevents dirt and moisture from entering the bearing and extending its life. The seals also minimize friction and heat generation, ensuring smooth and efficient operation. NSK, on the other hand, focuses on innovation and sustainability Another popular material for deep groove ball bearings is ceramic. Ceramic materials offer several advantages over traditional metals, including lower weight, higher hardness, and improved resistance to heat and wear. These properties make ceramic bearings ideal for high-speed applications where precision and longevity are paramount These properties make ceramic bearings ideal for high-speed applications where precision and longevity are paramount
