Single row needle roller bearings include cylindrical rollers that are small in diameter relative to their length. Owing to their massive variety of rollers, the bearings have an excessive load-carrying capacity. The outer ring consists of two crucial flanges to inform the bearing axially and an annular groove with one or extra lubrication holes to facilitate relubrication. The internal ring consists of an extra lubrication hole.
