Feature of needle roller bearing

Needle roller bearing with rings of carbon chromium(bearing) steel have low sectional height and very high load carrying capacity for their size. They may be used with or without inner ring, depending on the application. Needle roller bearing with inner ring are used for arrangements where it is not possible, or not economic, to harden and grind the shaft. Bearing with inner ring only permit axial displacement of the shaft relative to the housing within certain limits. If this is insufficient it is possible to use an extended inner ring instead of the standard inner ring. Drawn cup needle roller bearings, as the name suggests, are needle roller bearings with a deep drawn thin-walled outer ring with open or closed end. They are characterized by very low sectional height and high load carrying capacity. They are used when the housing bore cannot be used as a raceway for a needle roller and cage assembly but where a very compact and economic bearing arrangement is required. They are pressed into the housing bore and, if shoulders or retaining rings are not required for axial location, the design of the housing bore is simple and can be economically produced.
