Product Introduction

The NA series needle roller bearings are patented products of Ouye Bearings. They consist of an outer ring, a cage, needles, and an inner ring. The cage is positioned between the outer ring and the inner ring, with its two sides being movably connected to the opposite sides of the outer ring and the inner ring, respectively. The needles are movably connected internally to the cage. The inner side of the outer ring features an oil reservoir groove, and the inner wall of the outer ring has an oil injection hole. Since there are six reservoir grooves, evenly distributed around the cage, they can uniformly and continuously lubricate the surface of the needles when the bearing rotates, thereby improving the lubrication effect of the bearing.
