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.
