This needle roller bearing carries a solid outer ring without a flange, giving it a 37.0 mm outside diameter and a net mass of 78.45 g. The bearing runs with a standard cage and supports rotational speeds up to a limiting speed of 15800 1/min, with a reference speed of 9000 1/min under normal operating conditions. The absence of an inner ring keeps the radial section low, so this needle roller bearing is suited to installations where the shaft surface itself serves as the raceway, provided the required hardness and surface finish are maintained. The standard cage guides the needle rollers evenly around the circumference, supporting stable running behavior across the full speed range up to the limiting speed value.
