NTN Self-Aligning Ball Bearing 2200 Series Taper Hole 2204SK 1unit

It is a spherical surface with a point that coincides with the center of the raceway surface of the outer ring, and the inner ring is a ball bearing with two rows of raceway surfaces. The ball, cage, and inner ring can rotate at a certain degree of freedom with respect to the outer ring. Therefore, the deviation of the shaft center caused by the machining error of the shaft or the housing or the mounting of the bearing is automatically adjusted. However, since the load capacity of the axial load is not so large, it is not suitable for a place where the axial load is large. If an adapter is used for a bearing with a tapered hole inside, it is often used for a transmission shaft because it is easy to install and remove.
