Bearing unit with rolling elements

Abstract

A bearing unit comprising rolling elements, housed in a radially inner mounting seat of a casing. The bearing unit includes a radially outer and stationary coated ring provided with a metal ring and a liner of elastomeric material integral with a radially outer surface of the metal ring, a radially inner ring, which is rotatable with respect to an axis of rotation (X), and a row of rolling elements interposed between the coated ring and the radially inner ring. The elastomeric material of the liner is a vulcanized thermoplastic material. The liner is co-molded onto the radially outer surface of the metal ring and may include a cylindrical body and at least two annular protuberances which fit inside corresponding anchoring grooves formed on the surface of the metal ring.
