A bearing assembly including a bearing having a first ring with a hole, two front edges and an outer cylindrical surface, and a second ring with a hole, two radial edges and an outer cylindrical surface is provided. The first and second rings rotate relatively about a central axis. The bearing includes at least one row of rolling elements housed in a chamber formed between an outer cylindrical surface and a hole of the rings, the first and second rings and the rolling elements determining a pitch diameter of the bearing. A sealing means is provided having an engagement portion rigidly connected to one of the rings and a tapered annular body extending from the engagement portion towards the other ring. When idle, the body forms a non-zero angle with a plane perpendicular to the pitch diameter and is in direct or indirect contact with the other bearing ring. |

1. A bearing assembly comprising:
a bearing providing;
a first ring including a hole, two front edges and an outer cylindrical surface, anda second ring including a hole, two radial edges and an outer cylindrical surface, whereinthe first and second rings rotate relatively about a central axis (X1),at least one row of rolling elements housed in a bearing chamber formed between an outer cylindrical surface and a hole of the rings, the first and second rings and the rolling elements determining a pitch diameter (P1) of the bearing, and whereinthe assembly further includes at least one sealing means provided with an engagement portion rigidly connected to one of the rings and a tapered annular body extending from the engagement portion towards the other ring, such that when idle, the body forms a non-zero angle with a plane perpendicular to the pitch diameter (P1) and is in direct or indirect contact with the other ring of the bearing. |
