<p>PROBLEM TO BE SOLVED: To avoid local wear of a shaft and bearing, or at least decrease to a significant degree, in a friction region made complex with a high crosswise directed force. SOLUTION: A friction bearing is made of a sintered material of a hardening metal nature molded as specified previously followed by a sintering process having at least 15% open cavity volume. The local wear of a shaft and bearing is avoided or at least decreased to a significant extent in the friction region made complex with a high crosswise directed force to ensure that a bearing otherwise conventional is improved wherein the friction bearing is hardened after sintering.</p> |
