PROBLEM TO BE SOLVED: To obtain a rolling bearing which can sufficiently secure fletching resistance under a high-temperature environment, and in an oscillation rotation condition.SOLUTION: A rolling bearing comprises: a pair of bearing rings which are coaxially arranged with respect to each other, and have raceway surfaces at opposing faces; a plurality of pieces of rolling bodies which are rollingly arranged between both the bearing rings; and grease which is sealed into a space in which the rolling bodies are arranged between both the bearing rings. In the grease which is used in the bearing, fluorine-system oil whose kinematic viscosity at a temperature of 40°C is not higher than 80 mm/s is used as base oil, a thickener is formed of PTFE, and blending consistency at a temperature of 25°C is set at 300 or higher by a measuring method which is specified by JIS K 2220. |
