The NACHI 6308 deep groove ball bearing features an inner diameter of 40 mm, an outer diameter of 90 mm, and a width of 23 mm, designed for high rotational speeds and dynamic loads. It is a single-row bearing made of steel with options for open, shielded (6308Z, 6308ZZ), or sealed (6308DDU, 6308LLU, 6308-2NSE) configurations, providing protection against contaminants. The bearing supports radial load direction and includes a steel cage retainer. Its robust construction ensures durability in rotary and factory automation applications, with precision grade 0 and metric sizing standards for reliable performance. Weight is approximately 0.64 kg. Voltage and capacitance are not applicable as this is a mechanical component.
