Technical Design

Tapered roller bearings consist of four interdependent components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements), and the cage (roller retainer). These bearings are uniquely designed to manage both thrust and radial loads between rotating and non-rotating members. The steeper the cup angle, the greater the bearing's ability to handle thrust loads.

Excavator Bearing Installation & Removal

Proper installation and removal methods for excavator bearings should be based on bearing structure, size, and component compatibility. During installation and removal, pressure should be applied directly to the bearing ring's tight end surface, never through the rolling elements. Applying pressure through rolling elements can cause surface indentations that affect bearing performance and may lead to premature failure. Bearings, cages, seals, dust covers, and other components are susceptible to deformation, so pressure must not be applied to these delicate parts during installation or removal.
