Product Details

Needle roller bearing is a common rolling bearing, using needle roller as the rolling body, can withstand the radial and axial load.

Structure: Needle roller bearings are mainly composed of outer ring, inner ring, needle roller, cage and seal. The shape size of the needle roller bearing is small, saving space, suitable for limited space design. The inner ring and the outer ring are connected together by the needle roller assembly to keep the frame to separate the needle roller and ensure the normal operation of the needle roller.

Working principle: When the needle roller bearing is subjected to radial or axial load, the needle roller rolls between the inner and outer rings, reduces the friction between the bearing and the shaft, and improves the rotation efficiency of the bearing. Due to the large number of needle rolls, needle roller bearings can withstand higher loads than other rolling elements.
