CAT 495-4171 is the inner ring of a Caterpillar single-row tapered roller bearing. It is a matching inner ring for 495-4172 and is suitable for heavy-duty equipment with high-load transmission components. Key information is as follows:
Key Parameters
Item Details
Type: Separable inner ring of a single-row tapered roller bearing, capable of bearing only radial and unidirectional axial combined loads, requires a matching outer ring and roller assembly.
Dimensions (Metric/Imperial): Inner diameter 231.78mm (9.125 inches), width approximately 95.25mm (3.75 inches), raceway taper adapted for single-row tapered rollers, precisely matching the corresponding journal.
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 facilitates assembly and clearance adjustment, allowing for individual inner ring replacement during equipment overhauls, reducing maintenance costs.
Precision: Raceway surface roughness Ra≤0.4μm, raceway taper error≤0.005mm, ensuring precise contact with rollers and outer ring, reducing friction loss.
Suitable for: Output shafts, differentials, and main reducers in heavy equipment such as Cat 777G/775G mining dump trucks and D11T bulldozers, bearing combined radial and axial loads under heavy loads and impact vibrations, supporting stable operation of large journals.
Suitable for low-speed, heavy-load conditions in mining and infrastructure, meeting the need for individual inner ring replacement during equipment overhauls and extending the life of transmission components.
Performance Features: Separable design allows for the repair and replacement of corresponding tapered roller bearings without replacing the entire bearing assembly, reducing maintenance costs.
High-carbon chromium alloy steel with carburizing and quenching process provides excellent fatigue and impact resistance, extending the service life of bearing inner rings by approximately 30% compared to ordinary bearings.
High-precision raceway and tapered design ensure good contact with rollers and outer rings, reducing friction loss, improving transmission efficiency, and adapting to Caterpillar equipment’s high-precision transmission standards.
