<p>PROBLEM TO BE SOLVED: To provide a bearing device capable of avoiding heat problems while keeping dynamic friction torque low. SOLUTION: The number of pockets P in a cage 14 is twice the number of rollers 13A and 13B, and since some of the pockets P containing the rollers 13A and 13B and the other pockets P not containing the rollers 13A and 13B are arranged alternately in the circumferential direction, heating of the bearing due to friction at rolling contact portions between the rollers 13A and 13B and an outer ring 11 or an inner ring 12 and heating of the bearing due to the agitation resistance of oil can be reduced.</p> |
