Feature

●Ceramic bearings as a key mechanical base component have superior performance, heat resistance and super strength
●Simple design, easy to install and operate, easy to use
●The small balls on the ceramic roll are much denser and lighter than steel, reducing the centrifugal force of the outer ring by 40% while rotating, greatly increasing the life of the product
●Ceramic is virtually corrosion-resistant, and is a ceramic rolling bearing suitable for operation under harsh conditions full of corrosive media
●Ceramic elastic rate higher than steel is less likely to deformate under stress, it helps to improve working speed and achieve higher accuracy


Description
