803591100 Rear Bearing Outer Cover XCMG XDE130 Electric driving dump truck spare parts

The 803591100 rear bearing outer cover can solve problems such as axial movement of the rear bearing, grease leakage and loss, dust and mud intrusion, dry wear of the bearing, abnormal noise and vibration during operation, seal failure, and loose or misaligned assembly. It is suitable for scenarios such as replacement of old parts, maintenance of motor bearing systems, original factory assembly of new machines, repair of rear bearing failures, and upgrading of motor sealing structures. The product is made of high-strength cast iron, precision casting, fine machining, surface grinding, and rust and corrosion prevention processes. It has a dense and robust structure, precise flatness, and resistance 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 pollution, and outdoor temperature variations, providing long-term protection for the rear bearing and core transmission components of the motor.

Core technical parameters:

– Product Model: 803591100
-Product Name: Rear Bearing Outer Cover
– Material specifications: High-strength cast iron material, dense and hard structure, pressure and deformation resistant, wear and corrosion resistant, and stable and reliable sealing and protection performance.
– Processing technology: precision casting, fine machining, and surface grinding and calibration, all in accordance with the original manufacturer’s precision quality inspection process standards.
– Performance and operating condition adaptability: precise limit fixing, strong sealing and dustproof performance, shock resistance and anti-loosening, suitable for long-term high-frequency operation of motors.
– Structural features: Original factory standard specifications, precise alignment, tight fit, 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 assembly requirements of the motor’s rear bearing, ensuring a secure and airtight fit. 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 drive assembly structure, reducing the probability of equipment downtime, 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.
