This needle roller bearing is a yoke type track roller with a single row of needle rollers, featuring a particularly thick-walled outer ring, a needle roller and cage assembly, and an inner ring. The outer ring has no axial guidance and the design is open, with a bore diameter of 6.0 mm, an outside diameter of 19.0 mm, and a net mass of 14.2 g. The cage is executed in TV design, and the bearing is supplied without sealing. Inner ring, outer ring, and the needle roller and cage assembly can be mounted separately. The thick-walled outer ring gives the bearing high radial load capacity for its size, while the lack of axial guidance on the outer ring allows radial support without constraining axial movement. As the bearing is open and unsealed, mounting requires external protection against contamination and separate relubrication planning. The design permits individual fitting of the inner ring, outer ring, and needle roller and cage assembly, which simplifies assembly and replacement of worn components.
