Zusammenfassung:	A roller circle assembly for heavy machinery includes an upper circular rail and a lower circular rail concentrically arranged about a central axis, and tapered rollers between the upper and lower rail. Each tapered roller includes a flange having an angled and convex flange contact surface that contacts the lower rail. The lower rail and/or the upper rail can include an angled surface configured for contact with the flange contact surface. The geometry of the rollers and the lower rail are configured to reduce the stresses applied to the rollers and lower rail due to contact between the flange contact surface and the angled surface. Un assemblage de cercles de roulement pour machinerie lourde comprend un rail supérieur circulaire et un rail inférieur circulaire disposés de façon concentrique autour dun axe, et des rouleaux coniques placés entre le rail supérieur et le rail inférieur. Chaque rouleau conique comprend une bride présentant une surface de contact angulaire et convexe qui touche au rail inférieur. Le rail inférieur et/ou le rail supérieur peuvent comprendre une surface angulaire configurée pour toucher la surface de contact de la bride. La géométrie des rouleaux et du rail inférieur est configurée pour réduire le stress appliqué aux rouleaux et au rail inférieur en raison du contact entre la surface de contact de la bride et la surface angulaire.
