The SKF 6315-2RS1/C3 sealed deep groove ball bearing is engineered for substantial rotating assemblies requiring a 75mm shaft bore and a high-capacity bearing arrangement. Its 160mm outside diameter and 37mm width provide a robust 63 series cross-section, suitable for supporting predominantly radial loads together with axial forces in either direction, subject to the bearing's rated limits. SKF specifies a basic dynamic load rating of 119kN and a basic static load rating of 76.5kN, providing essential figures for fatigue-life calculations and assessment of stationary or peak loading. The SKF Explorer performance classification makes this a suitable option for demanding industrial applications when the complete operating conditions have been assessed.
The 2RS1 rubber contact seals retain factory-applied grease and help prevent dust, moisture and other contaminants entering the rolling elements. SKF specifies a limiting speed of 2,800rpm for this sealed configuration; this should not be confused with the higher reference speed quoted for other operating conditions. The C3 clearance suffix identifies greater-than-normal initial radial internal clearance, which can be beneficial where tight shaft fits or differential thermal expansion reduce clearance during service. However, C3 is not automatically appropriate for every installation, so operating temperature, fit and load conditions must be considered. This bearing uses a sheet metal cage and has no relubrication feature. For replacement work, confirm the entire 6315-2RS1/C3 designation, particularly the seal arrangement and clearance class, before fitting.
