 Needle Rollers are mainly known as Rolling Element but also act as Bearing if to be used on hard shaft and housing. Needle rollers are used where radial load and medium speeds are encountered. Needle rollers can also be useful in applications where the bearing envelope dimensions need to be kept to a minimum. Needle rollers tend to have slightly rounded ends as a stress-relieving feature, improving performance and life characteristics.
Application
 Precision Needle Roller Bearings and cylindrical rollers have multiple uses in a variety of industries including automotive, textile and electrical equipments. They are mainly used as bearing rolling elements to transmit torque and reduce friction. In addition they can also serve as precision shafts or as precision locating pins in some applications.
