The SKF RNU203ECP is a high-quality single row cylindrical roller bearing, featuring a 17 mm bore, 40 mm outer diameter, and 12 mm width. This bearing is designed for applications requiring high radial load capacity and high speeds. Its 'RNU' designation indicates no ribs on the inner ring and two ribs on the outer ring, allowing for axial displacement of the shaft relative to the housing. The 'ECP' suffix signifies an optimized internal design with a glass fibre reinforced polyamide 6,6 cage, roller centred, ensuring durability and reliable performance in demanding industrial environments. It has a basic dynamic load rating of 19.5 kN and a static load rating of 11.8 kN.
