N309
The N309 is a cylindrical roller bearing with 45mm bore diameter, 100mm outside diameter, and 25mm width. Cylindrical roller bearings use cylindrical rolling elements to provide high radial load capacity and allow for axial shaft displacement within the bearing.
This bearing type is commonly used in electric motors, gearboxes, machine tool spindles, and general industrial machinery where high radial loads and moderate speeds are present. The single-row design offers rigidity and precision in radial load applications.
