803590931 Bearing XCMG XDE130 Electric driving dump truck spare parts

The 803590931 bearing can solve problems such as excessive friction in motor shafts, abnormal noise and jamming during operation, high-speed vibration and eccentricity, lubrication failure and overheating, ball wear and jamming, shaft misalignment, and reduced lifespan during high-speed operation. It is suitable for scenarios such as replacing old parts, whole-machine maintenance of motors, original factory assembly of new machines, repair of rotational faults, and upgrading of motor operation performance. The product is made of high-hardness bearing-specific steel, which is precision quenched and hardened, ultra-precision ground, clearance calibrated, and treated with rust prevention and temperature resistance. The balls are round and regular, with precise fit clearance. It has the characteristics of low friction coefficient, high temperature resistance, high speed resistance, fatigue resistance, and resistance to wear and jamming. It is suitable for harsh working conditions such as high-speed rotation, continuous vibration, alternating load, and large temperature difference of motors, and ensures smooth operation and structural stability of motor shafts for a long time.

Core technical parameters:

– Product Model: 803590931
-Product Name: Bearing
– Material specifications: High-hardness bearing steel, with high hardness, strong wear resistance, high temperature resistance, fatigue resistance, and is not easily worn during operation.
– Processing technology: precision quenching and hardening, ultra-precision grinding and polishing, gap calibration, in accordance with the original factory quality inspection standards.
– Performance and operating condition adaptation: wear reduction and noise reduction, high-speed stable operation, temperature resistance and durability, suitable for high-frequency and high-speed motor operation conditions.
