Rolling elements play a critical role in rolling bearings, allowing for relative motion between two surfaces. Rolling elements are placed between inner ring and outer ring, enabling the bearing to be rotated with minimal friction. The shape, quantity and size variations determine the dynamic loads that a bearing can support.

Rolling elements are classified into steel balls and rollers. The steel balls are used in ball bearings, while the rollers can be further divided according to the shape of the roller into taper rollers, cylindrical rollers and spherical rollers.

ZHENSHUO has established long-lasting partnership with several trustworthy bearing roller manufacturers, and we have continuously provided high quality bearing steel balls and cylindrical rollers to Ukrainian HARP bearing plant for 6 years. The quality of rolling elements is particularly appreciated by the customer.
