NA4910 needle bearing

NA4910 needle bearing

NA4910 Needle bearings are composed of outer ring, inner ring and cage and needle roller components. They are the most widely used in different types of automobiles, machine tools, textile machinery, printing machinery, etc.

On mechanical equipment. Needle roller bearings can withstand large radial loads. This type of bearing has inner ring and no inner ring, assembled G2 needle roller, the average diameter of the upper and lower deviation is within 2um, using a high-rigidity cage, can correctly guide the needle parallel to the axis.
