CATERPILLAR 140 GRADER
SPEC SHEET
CRITICAL DIMENSIONS
Cross-section drawing of the K-RB-CAT140 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.
| REF | DIMENSION | VALUE | TOLERANCE |
|---|---|---|---|
| A | Rim base flange-to-flange | 438.5 mm | ±0.50 mm |
| B | Outer flange ⌀ | 635 mm | ±0.30 mm |
| C | Mounting flange ⌀ | 609 mm | ±0.30 mm |
| D | Lock-ring seat ⌀ | 562 mm | ±0.20 mm |
WHEEL-END ANATOMY
The complete CATERPILLAR 140 GRADER 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-CAT140 was meshed at refined element size with concentration at the lock-ring seat and bead radii — the two locations where field failures historically initiate.
