The 6303ZZ deep groove ball bearing features a 17mm bore diameter, 47mm outer diameter, and 14mm width, constructed from high carbon 52100 chrome steel with a pressed steel cage. It is double shielded with steel shields (ZZ) to protect against contamination while maintaining low friction. This bearing supports a dynamic load capacity around 13,500 N (approximately 3,060 lbs) and a static load capacity near 6,550 N (1,470 lbs), with a maximum speed of up to 18,000 RPM depending on lubrication. It operates reliably within a temperature range from -40°C to 175°C and is suitable for various industrial applications requiring durable, precision radial support.
