174-4504: Bearing – Cup(Debris Resistant)

CAT 174-4504 is a single-row tapered roller bearing cup only manufactured by Caterpillar. It must be used with a corresponding inner ring and is suitable for heavy-duty off-road equipment drive systems. Here is the core information:

Core Parameters
Item Details
Suitable Inner Ring Inner Diameter
Typical inner ring for tapered roller bearings with an inner diameter of 10.5 inches (266.7 mm)
Width
4.0625 inches (103.1875 mm)

Material
Bearing-grade alloy steel, carburized and quenched, high surface hardness, good core toughness, strong fatigue resistance and wear resistance

Structure
Monomeric outer ring with tapered raceways, used in combination with the corresponding inner ring (including rollers and cage), separable design for easy assembly and clearance adjustment

Application Scenarios
Suitable for heavy-duty transmission components such as differentials, axles, and final drives in mining trucks such as the Cat 793 series, bearing combined radial and unidirectional axial loads, suitable for high-load, impact-vibration mining conditions.

Used in power transmission systems to ensure stable operation of transmission components, reduce friction and wear, and extend equipment service life.

Performance Characteristics
**A specialized heat treatment process gives the outer raceway high hardness and excellent contact precision, reducing friction loss and resulting in fatigue life superior to industry standards under harsh operating conditions.**
**Suitable for dusty, heavy-duty operating environments.** When used with corresponding inner rings and seals, it effectively prevents contaminant intrusion and maintains a lubrication environment.

The detachable structure facilitates installation, maintenance, and clearance adjustment, meeting the high-precision assembly and maintenance requirements of Cat equipment.
