This needle roller bearing carries a solid outer ring without a flange, with an outside diameter of 78.0 mm and a net mass of 222.2 g. It belongs to the light series and is fitted with a standard cage. The limiting speed reaches 7200 1/min, while the reference speed is rated at 4500 1/min. The design without an inner ring keeps radial section height low, which allows a compact bearing arrangement where the shaft surface itself acts as the inner raceway. The standard cage guides the needle rollers and maintains even load distribution, making this bearing suitable for radial loads where the light series geometry and full use of the cross-section are required. Running at the given reference speed provides thermally stable operation, while the limiting speed defines the mechanical threshold for the cage and rollers.
