380902164 XCMG GR2605 motor grader slewing bearing

Core Product Advantages

Designed specifically for the XCMG GR2605 grader chassis and working device system, the mounting holes, pitch circle diameter, gear module, and connection dimensions are manufactured strictly according to original factory standards, ensuring a perfect match with the frame and slewing mechanism, eliminating the need for secondary processing after installation. Utilizing a heavy-duty, high-precision rolling element structure, the inner and outer rings and raceways undergo precision heat treatment and grinding, resulting in extremely high axial and radial load-bearing capacity. It can withstand heavy loads, overturning moments, and combined impacts, ensuring stable, unbiased, and jam-free operation. The high-precision gear ring ensures smooth meshing, stable and impact-free rotation, and low noise, guaranteeing smooth blade movement and significantly improving the accuracy of site leveling and slope trimming operations. The reliable overall sealing structure is dustproof, waterproof, and prevents mud and sand, effectively preventing external impurities from entering the raceways, extending the internal lubrication life, and adapting to harsh working conditions such as mines, construction sites, muddy areas, and dusty environments. High-strength integral forging process, fatigue-resistant, not easily deformed, not easily cracked, and long service life; convenient installation and maintenance, directly replaces the original slewing bearing, quickly solving problems such as loose slewing, abnormal noise, jamming, and swaying.
