IKO Needle Roller Ball Bearing

19mm Needle Roller Ball Bearing is a combination of two types of rolling elements: needle rollers and balls. Typically, the term "needle roller bearing" refers to bearings that use cylindrical, needle-shaped rollers to carry heavy radial loads, while ball bearings use spherical balls for similar purposes. In some designs, both types of rolling elements are integrated into a bearing assembly to provide a unique set of benefits that combine the advantages of both needle rollers and balls.
