PURPOSE: A bearing assembly is provided to simplify assembling process by fixing a ball simply with single structure, and to reduce manufacturing expenses and working hours by forming a retainer with injecting plastic. CONSTITUTION: A retainer(10) is composed of a body(11) placed between an outer ring(1) and an inner ring(2) with an empty circle in the middle, and plural fixing bodies(12) protruded around the body. The retainer is formed with injecting plastic with single structure to fix a ball(3) of a bearing. The ball is inserted to the fixing body, and ends of two fixing bodies are faced to each other. The distance between facing ends is smaller than the diameter of the ball to prevent the ball from the fixing body. The thin ends of fixing bodies are widened around balls in inserting balls. The retainer is inserted to the ball between inner and outer rings, and ends of the fixing bodies are widened. Manufacturing process is simplified, and working hours and failure rate are reduced with fixing the ball by inserting.
