CAT 495-4172 is a Caterpillar single-row tapered roller bearing inner ring, suitable for large journals in heavy-duty equipment drive systems, used for transmitting radial and axial loads under heavy-duty conditions. Key information is as follows:
Key Parameters
Item Details
Type: Single-row tapered roller bearing inner ring (inner ring only, requires a corresponding outer ring and roller assembly), suitable for combined radial and unidirectional axial loads (Cat® Parts)
Suitable inner diameter: 231.78mm (9.125 inches), precisely matching the corresponding journal size
Width: Approximately 114.3mm (4.5 inches), ensuring load-bearing area and installation positioning accuracy
Material: Bearing-grade high-carbon chromium alloy steel, carburized and quenched, surface hardness HRC60-64, high core toughness, fatigue and impact resistance, suitable for heavy-duty impact conditions
Structure Separable inner ring with tapered raceway; raceway taper adapts to single-row tapered rollers, facilitating assembly and clearance adjustment, suitable for equipment overhaul and maintenance needs.
Precision: High-precision raceway machining; raceway surface roughness Ra≤0.4μm, raceway taper error≤0.005mm, ensuring contact accuracy with rollers and outer ring.
Suitable Applications: Suitable for output shafts, differentials, and main reducers of heavy equipment such as Cat 777G/775G mining dump trucks and D11T bulldozers, used for journal support in high-load transmission systems, bearing combined radial and axial loads under heavy loads and impact vibration conditions.
Used in harsh working conditions such as mining and infrastructure, suitable for low-speed, heavy-load power transmission needs, extending the service life of transmission components.
Performance Characteristics: Inner ring only structure, compatible with the repair and replacement of corresponding Caterpillar single-row tapered roller bearings, reducing maintenance costs without requiring replacement of the entire bearing assembly.
Made of high-carbon chromium alloy steel with a carburizing and quenching process, it boasts excellent fatigue and impact resistance, extending the service life of ordinary bearing inner rings by approximately 30%.
High-precision raceways and tapered designs ensure good contact with the rollers and outer ring, reducing frictional loss, improving transmission efficiency, and conforming to Caterpillar equipment’s high-precision transmission standards.
