The outer ball bearing races (16, 26) of two ball bearings (12, 14) are supported on each other through a cardan joint (42). Axial bias forces in opposite directions are exerted on the inner ball bearing races (18, 28) by screws (44, 50) through cardan joints (48, 54). When the ball bearings rotate the outer ball bearing races (16, 26) are aligned. By means of a curing bonding agent the outer ball bearing races (16, 26) are fixed in a bearing sleeve (10) and the inner ball bearing races (18, 28) are fixed to a shaft (36) when the ball bearings rotate. |
