China factory needle roller bearing NA6915

Needle roller bearings are rotational motion bearings in which a thin needle-shaped roller is incorporated into a rolling element. They have a low cross-section height and high load capacity compared with ball bearings. Being small, needle roller bearings contribute to reducing overall machine size, and are thus widely used in various applications such as automobiles, motorcycles, printing presses, industrial robots and construction equipment.
