397-8783: 63.033mm Outside Diameter Needle Bearing

The Needle Bearing serves the minimize friction between moving parts and supporting radial loads. Needle Bearing stems from the appearance of its rolling elements, which closely resemble a series of slender, cylindrical needles. The point contact between the needle rollers and the raceways results in reduced friction, enabling smooth rotation and efficient power transmission. This feature is especially valuable in high-speed applications, where minimizing friction and energy losses is critical for achieving optimal performance and efficiency. Attributes: • Efficient load distribution along the length of the needle rollers • Ability to handle both radial and axial loads • Suitable for high-speed applications due to reduced friction • High precision and accuracy in operation Applications: This Needle Bearing is fixed at the Gear System to reduce friction and support radial loads.
