Abstract
PURPOSE:To prevent that water or foreign matter comes into the inside of bearing through the gap between both ends, by sealing directly or indirectly the gap between end of inner ring spacer most closed to the inside of bearing and the end of inner ring touched to it. CONSTITUTION:In the multiple train conical roller bearing provided with double row outer race 11, double row outer race 2 without flange having inner trace 21 opposed to inside trace 11 axially on inner race 1, single row outer race 3 without flanged opposed to outer trace 11 of above inner race 1, the above inner race 1 is arranged axially through the space 4, the gap between both ends 1, 4 opposed is sealed with seal 5. Seal 6 composed of inserting ring 61 and oil seal 62 is installed on the end of opposed side of spacer 4 of the above outer race 3. Additionally tapered surface 14 is formed on the end of spacer 4 of inner race 1.
