Игольчатый роликовый подшипник шестерни планетарной передачи Caterpillar 5392442

A Planetary Gear Needle Roller Bearing uses slender rollers to support radial and thrust loads within planetary gear assemblies. It consists of thin cylindrical rollers significantly longer than their diameter, enabling them to handle high radial loads with minimal radial space. The rollers are retained and guided by a cage, providing accurate roller movement within the bearing.Attributes:• Facilitates efficient and smooth power transfer in final drives• Absorbs shocks and vibrations, safeguarding planetary gear componentsApplications:A Planetary Gear Needle Roller Bearing supports the rotation of planet gears relative to the sun gear and ring gear. The needle rollers distribute the loads across the raceways, minimizing stress concentration and friction.
