PURPOSE:To eliminate the core holding mechanism for inside annular member while to reduce the leakage loss of lubricant by employing a conical tapered face having the rotary member as the symmetrical axis for the facing surface between inside and outside annular members. CONSTITUTION:A roll bearing 2 for a rotary shaft 1 is supported through coaxial inside and outside annular members 12, 13 on a bearing table 4. Said members 12, 13 have circular cross-section near to triangle while the facing surface is tapered. The tapered face is conical while having the rotary member 1 as the symmetrical axis, and upon application of load in radial direction, the inside annular member 12 will slide along said tapered face in axial direction. While a gap 6 is formed in the radial direction between the outercircumferential face of the outside annular member 13 and the bearing table 4. |
