4M-0546: 19.05mm Inner Diameter Needle Roller Bearing

A Needle Roller Bearing is a type of roller bearing that uses cylindrical rollers with a small diameter called needles, instead of the larger balls found in other types of bearings. The needles are held in place by a cage or retainer, which keeps them evenly spaced and prevents them from contacting each other. Attributes: • Provided linear contact areas with outer rings to distribute loads on the larger surface area. • Designed to reduce friction and improve efficiency. • Provide high radial stiffness. • Designed to operate in high-temperature environments. Applications: A Needle Roller Bearing is used in Starting Motor due to its high load-carrying capacity and ability to handle axial loads.
