A casing of a bearing unit for food applications may include a base having at least one hole for housing at least one fixing bolts, a spherical seat for housing the bearing unit, and at least one reinforcement rib located between the hole and the spherical seat.

Casing reinforced with ribs for food applications

A bearing unit having a stationary radially outer ring provided with a raceway, a radially inner ring rotatable about a central rotation axis (X) of the bearing unit and provided with a raceway, a row of rolling elements interposed between the radially outer ring and the radially inner ring, at least one sealing device mounted by means of interference on the radially outer ring and in sliding contact with the radially inner ring, wherein both the radially outer ring and the radially inner ring are made of low carbon steel with a minimum percentage by weight of carbon equal to 0.42%, and a central portion of the radially outer ring situated along the raceway and a central portion of the radially inner ring situated along the raceway are heat treated by means of induction hardening.

Bearing unit made of low carbon steel

A housing element having a casing provided with a spherical seat, a bearing unit located inside the spherical seat of the casing and provided with a radially inner ring, and a plastic end cover provided with a radial through-hole so that a machine shaft can be inserted inside it, the end cover being integral with the shaft and rotatable with the shaft, and the end cover being provided with an elastomeric seal for forming a static seal on the shaft.
