A hub bearing assembly includes a housing with a vertical bore, a bearing outer ring disposed within the bore and coupled with the housing and a bearing inner ring disposed within the bearing outer ring and having a central bore configured to receive a portion of the shaft. A set of rolling elements are disposed between the bearing outer and inner rings. An upper seal is disposed within the housing bore externally of the outer ring and includes an annular elastomeric seal body and a garter spring biasing a seal lip radially inwardly. A lower seal is disposed between the bearing outer and inner rings. Either the bearing inner ring is sized such that upper seal is disposed about the bearing inner ring or the hub bearing assembly further comprises an annular spacer disposed within the upper seal and adjacent to the upper axial end of the bearing inner ring.

Hub bearing assembly

A pulley assembly for belt tensioners having a bearing unit provided with a rotating outer ring and made of metal, an outer wheel body overmoulded onto the outer ring to rotate with the outer ring and interact with a belt, a gripping surface at the interface between the outer wheel body and the outer ring to prevent circumferential slipping between the outer wheel body and the outer ring; and an axial retainer integral with the outer ring and having two lateral edge members located axially on opposite sides of the gripping surface to engage the outer wheel body and prevent axial movement of the outer wheel body relative to the outer ring.

Pulley assembly

A hub bearing assembly for the rotatable mounting of a soil cultivating disc (D) on a support shaft (A) of an agricultural machine, the assembly being provided with a hub bearing unit which in turn is provided with a flanged outer ring carrying two integral outer raceways for respective rows of rolling bodies, a flange fixed to the flanged outer ring for mounting a disc (D), and, for each outer raceway, an inner ring axially adjacent to the other inner ring, both of which can be engaged by the support shaft (A); and a sealing device mounted on a side of the hub bearing assembly opposite the side of the flange, composed of a first sealing stage and a second sealing stage arranged sequentially along the support shaft (A) and housed in respective seats formed directly in the flanged outer ring.

Hub bearing assembly for discs for soil cultivation

A hub-bearing assembly serves to rotatably mount a soil-working disc (D) on a supporting axle (A) of an agricultural machine. The assembly comprises a hub-bearing unit () and a sealing device (). The a hub-bearing unit has a radially outer, rotatable outer race () from one side of which a flange () radially extends for mounting a disc (D). The sealing device () is mounted on a side of the hub-bearing unit opposite to the side of the flange (). The radially outer surface of the assembly has a portion () intermediate the flange () and the side of the sealing device (), which is radially recessed so as to serve as a preferential seat for winding wires picked up from the fields during use of the agricultural machine.
