The 47 mm steel sleeve bearing compatible with bearing numbers 6005, 6204, and 6303 features an outer diameter of approximately 50 mm (1.969 inches) with a tolerance of ±0.05 mm and a sleeve length of 20 mm. The 6204 bearing has dimensions of 20 mm inner diameter, 47 mm outer diameter, and 14 mm width, supporting dynamic loads up to 1000 kgf and speeds up to 18,000 RPM in open form. The 6303 bearing measures 17 mm inner diameter, 47 mm outer diameter, and 14 mm width, designed for high rotational speeds and dynamic loads with steel inner and outer rings. These bearings are deep groove ball types suitable for various machinery applications requiring reliable radial load support and high-speed performance. The steel sleeve ensures proper fit and alignment for these bearing sizes.
