Bearing Technical Information: Materials

This introduces information about the raceway of bearings and the materials of rolling elements.

NSK Micro Precision develops, manufactures, sells, and provides services for unit products that combine miniature ball bearings, miniature ball bearings, and precision machined parts. The raceway and rolling elements of the bearing undergo rolling contact with sliding while repeatedly receiving contact pressure. Therefore, multiple properties are required for the materials of the bearing's raceway and rolling elements. 【Properties required for the materials of the bearing's raceway and rolling elements】 ■ High rolling fatigue strength ■ High hardness ■ High wear resistance ■ Good dimensional stability ■ High mechanical strength ■ Ease of processing ■ Heat and corrosion resistance depending on the application *For more details, please refer to the PDF document or feel free to contact us.
