E12 belongs to the E series of magneto bearings and is classified as a separable single-row angular contact ball bearing. It is often referred to as a magneto angular contact ball bearing. Its typical features include a single-sided flange on the outer ring and the ability for the inner and outer rings to be separated and assembled. It is suitable for high-speed, light-load, and precision rotation scenarios that require the bearing of small amounts of axial force in both
