Excavator Bearing Installation Guidelines
Proper installation and removal of excavator bearings should be based on the bearing structure, size, and compatibility with excavator components. During installation, pressure should be applied directly to the tight end surface of the bearing ring, never through the rolling elements, as this can cause surface indentations that affect bearing performance and potentially damage the bearing.
Bearing cages, seals, dust covers, and other components are prone to deformation. Installation or removal pressure must not be applied to these delicate parts.
