This needle roller bearing is a single row design without an inner ring, with the outer ring featuring two ribs (bords) that axially locate the needle roller and cage assembly. Outside diameter is 65.0 mm and net mass is 0.161 kg. The bearing carries a standard cage and is rated for a limiting speed of 8900 1/min, with a reference speed of 5500 1/min. The absence of an inner ring allows the needle rollers to run directly on a hardened and ground shaft journal, which reduces radial section height and keeps the bearing compact for its load capacity. The two ribs on the outer ring retain the roller and cage set, simplifying mounting and handling before the shaft is inserted. The standard cage guides the needle rollers at even spacing, supporting stable operation up to the stated speed limits.
