Needle Roller Bearing INA. NRB AND SKF Supplier in Trichy A needle roller bearing is a type of roller bearing that uses long, thin cylindrical rollers to handle high loads in a compact space. These bearings are ideal for applications where radial space is limited, such as in automotive transmissions, industrial robots, and machinery, because they have a low sectional height but a high radial load capacity. They are categorized as radial or thrust bearings, depending on the direction of the load they are designed to support.
