Радиальный опорный подшипник гидронасоса Caterpillar 1248343

The Hydraulic Pump Journal Bearing is a sleeve-style bearing that supports the rotating shaft of a hydraulic pump, enabling it to spin freely with minimal resistance while maintaining accurate alignment. It operates under hydrodynamic lubrication, where a thin film of oil separates the shaft and bearing surfaces, preventing direct metal-to-metal contact.Attributes:• Supports the hydraulic pump shaft during rotation.• Minimizes friction using hydrodynamic oil film.• Maintains shaft alignment to prevent vibration and wear.• Handles continuous radial loads in pressurized environments.Applications: The Hydraulic Pump Journal Bearing is located inside the hydraulic pump housing, supporting the rotating drive shaft that transfers power from the engine or motor to the pump’s internal rotating components.
