Abstract: A hub-bearing assembly serves to rotatably mount a soil-working disc on a supporting axle of an agricultural machine. The assembly includes a hub-bearing unit having a radially outer, rotatable outer race from one side of which a flange radially extends for mounting a disc. A sealing device is mounted on an inner side of the hub-bearing unit opposite to the side of the flange. The radially outer surface of the assembly has a portion between the flange and an inner side of the outer race, which is radially recessed so as to serve as a seat for winding agricultural fibers or wires picked up from the fields during use of the agricultural machine. At least one cutting projection extends radially outwardly from the recess to at least facilitate removal of fibers or wires.

Abstract: A bearing unit configured to be clamped on a machine shaft includes a stationary radially outer ring, a rotatable radially inner ring having a radially inner surface, a row of rolling bodies interposed between the radially outer ring and the radially inner ring, and a clamping device that includes a clamping sleeve between the radially inner ring and the machine shaft, the clamping sleeve including a threaded flange portion and a circumferential slit configured to deform and tighten around the machine shaft, and a ring nut to screw onto the threaded flange portion and exert an axial force on the radially inner ring, the radially inner surface of the radially inner ring engages the radially outer surface of the clamping sleeve.

Abstract: A bearing unit with rolling bodies for use in the food and beverage industry, for example, is disclosed herein. The example embodiments disclosed herein provide that of a bearing unit comprising a radially inner ring including a stainless steel collar with a raceway, on which two sleeves made of reinforced polymeric material are co-molded on opposite sides. Such example embodiments incorporate corrosion resistance properties of a polymeric material without losing the surface hardness properties. As such, the radially inner ring of the bearing unit offers same nominal load values as inner rings are made entirely of metal, but with better corrosion resistance without losing the surface hardness properties.
