This needle roller bearing is a double row design in dimension series 69, with a bore diameter of 50.0 mm, outside diameter of 72.0 mm, and width of 40.0 mm. Net mass is 0.514 kg. The bearing uses a standard cage and reaches a limiting speed of 7800 1/min, with a reference speed of 4200 1/min. The double row arrangement (ZW) increases radial load capacity within a compact cross-section, making the bearing suitable for locations where high loads must be carried with limited radial space. The standard cage guides the needle rollers evenly around the bore, supporting stable running at the stated speed limits. As a needle roller bearing without integrated sealing, it requires external sealing and a separate lubrication supply, and mounting must account for the absence of an inner ring in this design.
