The CAT 174-5296 is Caterpillar’s Debris Resistant Tapered Roller Bearing Cup, designed for heavy-duty equipment operating in dusty, high-impact conditions. Its core advantages are outstanding raceway contamination resistance and wear resistance. Key information is as follows:
Core Parameters
Item Details
Matching Inner Ring
Matches CAT’s corresponding inner diameter of approximately 10.5 inches (266.7 mm) with a Debris Resistant Tapered Roller Inner Ring (e.g., CAT 174-5297)
Outer Diameter
Approximately 15.0 inches (381 mm), suitable for Cat mining truck and other equipment bearing housings
Width
Approximately 4.0625 inches (103.1875 mm), ensuring roller contact accuracy and load-bearing area
Material
Bearing-grade alloy steel, carburized and quenched, surface hardness HRC60-64, high core toughness, fatigue resistance, and impact resistance
Debris Resistant Design The raceway surface features a special wear-resistant coating and an optimized sealing groove structure, effectively preventing the intrusion of dust, ore debris, and other contaminants, making it suitable for harsh working conditions such as mines.
Structure: A single outer ring with a tapered raceway, separable from the inner ring for easy assembly, maintenance, and clearance adjustment.
Applications: Suitable for differentials, axles, final drives, and other components in heavy-duty equipment such as Cat 793 series mining trucks and large loaders. It withstands combined radial and unidirectional axial loads and is commonly used in dusty, high-impact heavy-duty operations such as mining and infrastructure projects.
Used in transmission systems, it protects the internal lubrication environment of bearings, reduces wear caused by contaminants, and extends the overall service life of transmission components.
Performance Characteristics: The anti-debris coating and sealing groove design increase service life by approximately 30% in dusty conditions compared to ordinary outer rings, reducing equipment downtime for maintenance.
High-precision raceway machining ensures good contact with the inner ring and rollers, reducing friction loss, improving transmission efficiency, and reducing energy consumption.
The detachable structure is compatible with the high-precision installation requirements of Cat equipment, facilitating quick replacement during on-site maintenance and reducing downtime.
