Needle Roller Bearings By Qingdao Autos Ball Bearing Co.,ltd.

We are one of the biggest manufacturers and exporters of Needle Roller Bearings in Qingdao, Shandong, China. Needle roller bearings are roller bearings with cylindrical rollers that are long and thin in relation to their diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited. Needle bearings are designed to support radial loads and reduce friction between rotating components. The low cross section provides maximum load-carrying capability with a minimum of space required. Drawn cup bearings are easily installed with a press fit in the housing.A There are two basic designs: The full complement and the caged version. Both have a drawn outer shell that serves as a raceway for the rollers contained in the bearing.
