800554577 XCMG GR2605 motor grader bearing 81211

800554577 (Model 81211) is a thrust cylindrical roller bearing specifically designed for XCMG GR2605 motor graders. Primarily designed to withstand axial loads, it boasts high load-bearing capacity, wear resistance, and pressure resistance. Used in axially stressed components such as gearboxes and drive axles, it ensures stable and reliable transmission.

Core Functions and Roles

Specifically designed to withstand large unidirectional or bidirectional axial forces, preventing axial movement of shaft components, ensuring stable clearances in gear and bearing assemblies, and preventing abnormal noise and impact.

Made of high-precision bearing steel, with a large contact area between the rollers and raceways, it is wear-resistant, pressure-resistant, and fatigue-resistant, suitable for heavy-duty and continuous operation conditions in motor graders.

It features good structural rigidity, high operational precision, and a tight fit with the shaft and bearing housing, ensuring accurate axial positioning of transmission components and extending the life of gears and bearings.
