has a greater rated load

Compared to the general ball and rolling Backing bearings  in the same space that can withstand the environment greater rated load, at the same time, because there is no inner ring, roller bearings can pass through the rolling roller and cage assembly, effective reducing the size and weight of the bearing itself, so that the bearing device is designed in the combination of mechanical fit more compact, provide effective utilization of space to engage the machine itself.

(2) a smaller cross-sectional height
Smaller section height, which means needle roller bearings in a more confined space can play environment, thus completing other types of bearings impossible task. Meanwhile, the bearing in operation and maintenance will also be more easy!

3 can withstand high-speed rotation
Ball bearings and with the general roll shaft bearing, needle roller bearing pitch circle diameter is smaller. As the temperature changes, the bearing load and speed of rotation affected by it is very limited, which makes it can be compared to other high-speed rotation of the bearing has a more prominent advantages.

4 multi-needle rolling elements
Bearing load balancing can be effectively applied to the needle and needle roller bearings above, so that you can have a greater load bearing capacity. Since the needle bearing relative to the average diameter of the rolling element rolling roller body concerned is relatively small, so that the bearing needle bearing can withstand cyclic oscillating persistent negative effects generated by the rotation, which is the most needle bearings one distinct advantage.
