803591097 Rear Bearing Inner Cover XCMG XDE130 Electric driving dump truck spare parts

The 803591097 rear bearing inner cover can solve problems such as rear bearing internal movement, grease leakage, dust and mud intrusion, bearing eccentric operation, accelerated wear, abnormal operating noise, seal failure, and loose positioning. It is suitable for scenarios such as old part replacement, motor bearing maintenance, new machine original factory assembly, rear bearing protection and repair, and motor structure reinforcement and upgrade. The product is made of high-strength cast iron, precision casting, fine machining, surface grinding, and anti-corrosion and rust prevention processes. It has a dense structure, high flatness, and is resistant to pressure and deformation. It has the characteristics of shock resistance, pressure resistance, tight sealing, wear resistance, corrosion resistance, and fatigue deformation resistance. It is suitable for the harsh working conditions of engineering machinery with high-frequency vibration, dust and oil, and outdoor temperature variation, and provides long-term protection for the rear bearing and internal core components of the motor.

Core technical parameters:

– Product Model: 803591097
-Product Name: Rear Bearing Inner Cover
– Material specifications: High-strength cast iron material, dense and hard structure, pressure and deformation resistant, wear and corrosion resistant, and stable positioning and sealing performance.
– Processing technology: precision casting, fine machining, and surface grinding and calibration, strictly following the original manufacturer’s precision quality inspection standards.
– Performance and operating condition adaptability: precise limit, excellent sealing protection, shock resistance and anti-loosening, suitable for long-term high-frequency transmission operation of motors.
– Structural features: Original factory standard specifications, high fit, precise alignment, convenient disassembly and assembly, effectively reducing motor maintenance and repair costs.

This product undergoes multiple specialized tests before leaving the factory, including dimensional accuracy, flatness verification, pressure resistance and durability, sealing compatibility, shock resistance and anti-loosening, and dust protection, meeting the original equipment manufacturer (OEM) assembly standards for construction machinery. After installation, it precisely matches the inner side of the motor’s rear bearing, ensuring secure positioning and a tight seal. This completely eliminates problems such as bearing movement, grease leakage, dust ingress and wear, and abnormal operating noises, effectively extending the service life of the rear bearing, stabilizing the motor transmission structure, reducing the probability of downtime due to malfunctions, decreasing the frequency of routine maintenance, and providing long-term protection for the safe, stable, and efficient operation of the construction machinery’s motor system.
