SKF NU2304ECP bearing

20x52x21

The SKF deep groove ball bearing is a double-sealed ball bearing with C3 clearance and has a deep-groove geometry for high speeds and supporting both radial and axial loads. This bearing has C3 radial internal clearance for radial slack between the inner and outer rings that is greater than CN (normal) to compensate for thermal expansion.
