Игольчатый подшипник Caterpillar 4898206

The Needle Bearing is a type of roller bearing commonly used in transmission systems, including in planetary gear sets. Needle bearings are often used to support and allow relative motion between the gear elements, such as sun gears, planet gears, and ring gears. Needle bearings consist of cylindrical rolling elements with a long and thin shape, resembling needles. These bearings have a large surface area in contact with the shaft or housing, which helps distribute the load more evenly and reduces friction compared to other bearing types.Attributes:• Cage coating phosphate• Cage finish isotropic• Static capacity 131 KN• Dynamic capacity 95.7 KN• Reduces friction losses, improves efficiency, and enables smoother operation• Increases load-carrying capacity, ideal for high-torque and high-speed applications• Distributes loads evenly, minimizes wear, and enhances transmission performance• Reduces the size and weight of the gear setsApplications:This Needle Bearing is located in transmission planetary groups to provide support and allow relative motion between gear elements while minimizing friction and ensuring efficient power transmission.
