<p>The cage (6) has a set of crosspieces (10) extended between outer and inner rims (8, 9) to form a conical roller holding housing (7) between the crosspieces, where the cage is made of metallic material and is formed by machining. The rim (9) has a diameter lesser than diameter of the rim (8). The rim (9) has an open notch (11) that is arranged for permitting diameter variation of the rim (9) by elastic deformation of the cage. The notch has an opening with a width lower than 1 millimeter.</p> |
