379-5477: 76.2mm 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: • 155 Needless per Bearing. • Designed to reduce friction and improve efficiency. • Provide high radial stiffness. • Designed to operate in high-temperature environments. Applications: A Needle Roller Bearing used in Reduction Gear to support the rotating shaft that connects the input and output gears.
