Needle roller bearings can carry high radial loads due to the large contact area of the rolling elements; they are not designed to carry axial loads. Some needle bearings are equipped with an inner race, but some have no inner race. In cases where no inner race is present, the shaft forms the inner race.
What part of the bearing is the race?
The inner race, or cone, is the part of the bearing that sits directly on the shaft. The rolling elements, shaped as balls or rollers, provide the cushion that eases the moving friction of the shaft within its housing. These elements keep the outer and inner races separated and enable them to move smoothly and freely.
What is inner ring in bearing?
Inner ring is used as basic parts of Needle Roller Bearing, in cases where a raceway cannot be provided directly on the shaft, SYI inner rings permit practical and economical design solution.
