Product Description
SKF 4309ATN9 deep-groove ball bearing. Deep-groove ball bearing designed for combined radial and moderate axial load, high running speed and low frictional torque. Manufactured to ISO 492 (Class Normal / P6 / P5) with standard C0 radial internal clearance unless a suffix declares otherwise. Available in open, single-shielded (Z), double-shielded (2Z), single-lip contact-sealed (RSH / RS1), and double-lip contact-sealed (2RSH / 2RS1) execution. Bore, outside diameter and width follow the ISO 15 dimension plan. Bore diameter d = 45 mm per ISO 15.
