Single row needle roller bearings incorporate cylindrical rollers that are small in diameter relative to their length. Owing to their large number of rollers, the bearings have a high load carrying capacity. Bearings without flanges on the outer ring are separable, i.e. the outer ring and the needle roller and cage assembly can be mounted separately. The inner ring contains a lubrication hole to facilitate relubrication.
