About us:We are a professional bearing manufacturer. we are strict in the whole course from purchasing of raw materials to every process of production, our mission's commitment is to provide client right product and right service and right delivery time.
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.
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. The full complement version has the maximum number of rollers mechanically retained by the drawn outer shell. This design combines high radial load-carrying capability with low cost. The standard caged version contains a one-piece steel cage to guide and retain the rollers. This design provides high speed and maximum lubricant retention capability.
