  Needle Roller Bearings Market: Introduction The roller bearing clan comprises of tapered, cylindrical, needle and spherical bearings. The needle roller bearings are the lightest and the smallest of them all and hence the name. They have significant designing which can be used in various applications. Their size gives them edge in certain applications where less weight and less space are concerned. The ratio of the length of the roller and the diameter of the roller is very high making them look like needles and hence the name given to these type of bearings. The needle roller bearings have many configurations. There are different types of needle roller bearings – needle rollers, drawn-cup needle roller bearings, needle roller and cage assemblies, heavy duty needle bearings, thrust needle roller and cage assemblies, track rollers and airframe needle bearings. To reduce the stress concentrations at the roller-end or deflection of the raceways due to load, controlled contours have ...
