CRITICAL DIMENSIONS

Cross-section drawing of the K-RB-K930E7P rim assembly. Five reference dimensions (A–E) are CNC-machined to the tolerances called out in the table and verified on a 5-axis CMM before every unit ships.

WHEEL-END ANATOMY

The complete KOMATSU 930E 7-PIECE wheel-end is a five-piece assembly. Every Kelios rim ships as a matched set — rim base, lock ring, side rings, and bead seat band — with the OEM-supplied hub remaining factory original.

FINITE ELEMENT ANALYSIS

Every Kelios rim design is validated under 1.4× rated load in a Von Mises FEA solver before tooling is cut. The K-RB-K930E7P was meshed at refined element size with concentration at the lock-ring seat and bead radii — the two locations where field failures historically initiate.
