Product description
The EE2ZZ Neutral is a miniature ball bearing. This is a very small single-row deep groove ball bearing. The design consists of an inner and an outer ring, with a ball and cage assembly in between. Thanks to their simple construction, these bearings require little maintenance. With their compact dimensions, miniature bearings are suitable for applications where space is limited.
Additionally, miniature ball bearings boast significant radial load-bearing capacity. The cage of the EE2ZZ Neutral ensures that the balls do not touch each other and move in a controlled manner. This generates less heat and allows for high speeds to be reached. Miniature ball bearings are therefore widely used in situations where very high rotational rates are required.
