Игольчатый подшипник, внутренний диаметр 45 мм Caterpillar 5671738

The Needle Bearing used in a hydraulic pump shaft is a precision-engineered anti-friction component that supports the rotating shaft under high radial loads. Unlike conventional ball bearings, it uses slender, cylindrical rollers with a high length-to-diameter ratio, which allows it to handle loads in a compact space. The rollers are housed in a steel cage, which keeps them evenly spaced and guides their motion.Attributes:• Used for long service intervals.• High load-carrying capacity• Suitable for high-speed rotation and pressure environments.Applications: The Needle Bearing in hydraulic pumps is positioned around the shaft journals to support rotation and maintain alignment. These bearings reduce friction between the shaft and the pump housing, ensuring smoother motion and minimizing wear under high-pressure fluid operation.
