Abstract
The invention relates to universal machine parts, and more particularly to a curved groove ball bearing without a retainer, which can solve the problems in the prior at such as high pendulating frequency and small amplitude. For the bearing, an inner ring and an outer ring are respectively provided with a first curved groove and a second curved groove, where “peaks” and “valleys” of the first curved groove are respectively the same as those of the second curved groove in number. The second curved groove is filled with steel balls, and a retainer for fixing the relative positions of the steel balls is removed, increasing the amplitude and reducing the pendulating frequency.
