Provides the inner locating element for a needle roller bearing arrangement, machined to DIN 620 accuracy standards. Bore diameter is 15.0 mm, width is 12.0 mm, and net mass is 12.0 g. The ring carries a lubrication hole for supplying grease or oil directly to the raceway during operation. Being a separate inner ring, it allows the bearing arrangement to be assembled with a shaft-mounted raceway distinct from the outer roller and cage unit, simplifying mounting and dismounting on the shaft. The lubrication hole supports through-feed lubrication, keeping the rolling contact supplied without dismantling the assembly. Precision machining to DIN 620 ensures consistent fit and running accuracy on the shaft seat.
