E2-6007ZZ is a type of Energy efficient bearing

Single row deep groove ball bearings with seals or shields are specially versatile, have low friction and are optimized for low noise and low vibration, which permits excessive rotational speeds.

DIMENSIONS

This type of bearings are energy efficient bearing. Its material is chrome steel, and the cage is special material like rubber. This type bearing can work at very high speed and it's very low noise. 

This is our new products with high technology. The engineers have done a lot of research to make sure the bearings can use at a high speed.
