Abstract
【解決手段】 少なくとも1つの内リング(2)と、少なくとも1つの外リング(3)と、内リング(2)と外リング(3)との間に配置されるローラ体(4)とを備える軸受(1)において、軸受(1)は、少なくとも2列(5、6、7)のローラ体(4)を有し、ローラ体(4)の直径は全列(5、6、7)にとって等しい大きさであり、内リング(2)と外リング(3)の同軸配置での軸受(1)の無負荷状態において、内リング(2)と外リング(3)との間のレースウエイ(8、9、10、11、12、13)の間隔(a1、a2、a3)は、個々の列(5、6、7)において異なる大きさであるので、軸受配置の全ローラ体列は、軸の仮定または予想される湾曲の場合に予め計算できる軸の湾曲線により均等に負荷される。
