Provides the inner raceway for a needle roller bearing arrangement, machined to the tolerances of DIN 620. The ring has a bore diameter of 25.0 mm, a width of 16.0 mm and a net mass of 23.9 g, and includes a lubrication hole for feeding grease or oil directly to the roller path. The lubrication hole allows relubrication without dismantling the assembly, keeping the running surface fed during operation. As a separate inner ring, it is intended to be combined with a matching needle roller and outer bearing component, giving a compact radial arrangement where the shaft itself does not need to serve as the running surface. Precision machining of the ring ensures accurate seating and a true running surface for the rollers.
