This needle roller cage assembly guides two rows of needle rollers within a bore of 15 mm and outside diameter of 18 mm, at a width of 22.0 mm. The TV cage design holds the rollers in position and distributes them evenly around the raceway. Net mass is 4.56 g. The assembly is rated for a limiting speed of 24600 1/min and a reference speed of 17800 1/min. The two-row TV cage arrangement increases the number of load-carrying needle rollers within the given envelope dimensions compared to a single-row design, which raises the radial load capacity for the same bore and outside diameter. As a cage assembly, it requires a separate inner and outer raceway surface to run against, so the mounting surfaces must be hardened and ground to the correct tolerance for the rollers to operate correctly. Running accuracy and radial internal clearance depend on the mating raceway components selected alongside this cage assembly.
