    摘要: A bearing unit having a stationary radially outer ring, a radially inner ring, rotatable with respect to a rotation axis (X) and steadily connected to a rotating shaft, a row of rolling bodies interposed between the radially outer ring and the radially inner ring, a casing, inside which the rings of the bearing unit are housed, a sealing device, and a protection disk. The protection disk may be mounted in an axially external position to the sealing device and fixed to the radially inner ring. Additionally, the protection disk may have a shaped metallic screen, and an elastomer coating over-molded on part of the screen. The protection disk may further be in contact with an axially external surface of the radially outer ring through the elastomer coating, which is provided with two lips, a first lip, non-contacting or contacting and radially external, and a second lip, contacting and radially internal.

    摘要: A sealing system for food applications that provides a housing element with two or more bolts and respective holes for clamping. A flanged element is clamped to a frame of a machine, and a rubber seal placed along the base perimeter of the housing element. The seal includes a first portion of the rubber profile placed in the areas distant from the holes and a second portion of the rubber profile adjacent to the holes. The rubber profile of the second portion has a larger cross section than that of the first portion, such that the deformations of the rubber profile are made virtually uniform to prevent the formation of fractures, and therefore of bacteria traps, in the rubber.

    摘要: A support assembly for a moveable, rotating, or sliding shaft includes a casing and a cover. The casing includes a front edge defining an opening and a radially external lateral surface having an annular seat. The annular seat includes an annular groove axially spaced from the front edge and connected to a number of axial grooves that interrupt at least part of the front edge. The cover includes an annular coupling portion extending toward the radially external lateral surface of the casing. The annular coupling includes at least one pair of teeth formed on a radially inside surface of the annular coupling portion and projecting radially inward, each pair of teeth spaced circumferentially from each other, and a plurality of radially internal projections. A bottom wall of the annular groove includes a plurality of depressions alternating with a plurality of projections.
