The Nachi SH6-6311ZZEC3 is a ceramic hybrid deep groove ball bearing featuring ceramic balls and steel races, measuring 55 mm inner diameter, 120 mm outer diameter, and 29 mm width. It includes two metal shields (ZZ) for dust protection and has a C3 radial internal clearance for high-speed applications. This bearing offers lightweight, non-conductive ceramic balls with enhanced rigidity and reduced friction, suitable for speeds up to approximately 8,000 rpm. The ceramic hybrid design improves durability and performance under moderate loads and temperatures. The Nachi bearing is ideal for precision machinery requiring low noise and long service life.The Nachi 408 ceramic hybrid ball bearings combine ceramic balls with steel races, providing high stiffness, low friction, and excellent corrosion resistance. These bearings are designed for high-speed and high-precision applications, featuring robust construction and reduced electrical conductivity, making them suitable for demanding industrial environments.
