Imported Tapered Bearing Cup, 4.430"X0.930"

The 3920 Imported Tapered Bearing Cup is a precision outer race (cup) for 3900 series tapered roller bearing applications, commonly used in agricultural and industrial equipment. With a 4-7/16" cup outside diameter and 0.9375" cup width, it’s a straightforward replacement part with a long list of cross-references—because nothing says “universal language” like a bearing number.
