The window hole is used for fixing the rolling body and ensuring the high-speed stable operation of the bearing.

A bearing comprises an inner ring and an outer ring, wherein the spinning type conical retainer is arranged between the inner ring and the outer ring, a rolling body is further arranged between the inner ring and the outer ring, and the rolling body is arranged in a window hole of the spinning type conical bearing retainer. The bearing is applied to the field of wind power equipment.

The utility model has the beneficial effects that: the side plates and the bottom plate which form the retainer body and are integrally formed are manufactured by spinning processing, and are not required to be rolled and welded, so that the problems that the integral performance is different and the performance quality of a welding part is not easy to guarantee in the welding process are solved; the spinning forming die is simple, short in processing time, convenient for adjusting the angle and the height and the like, and has better product performance, reliable principle and very wide application prospect.
