CAT 488-1645 is a Caterpillar single-row tapered roller bearing, commonly used in heavy equipment transmission systems, suitable for heavy-load and impact conditions. The following is key information:
Key Parameters
Item Details
Type: Single-row tapered roller bearing, separable structure, withstands combined radial and unidirectional axial loads, suitable for high-precision positioning requirements of transmission components
Suitable Inner Diameter: Approximately 3.5 inches (88.9 mm), matching corresponding journal size
Outer Diameter: Approximately 6.0 inches (152.4 mm), suitable for housing mounting holes
Width: Approximately 1.875 inches (47.625 mm), ensuring load-bearing area and installation accuracy
Material: Bearing-grade high-carbon chromium alloy steel, carburized and quenched, surface hardness HRC60-64, high core toughness, fatigue and impact resistance
Structure: Separable inner ring, outer ring, and roller assembly, facilitating assembly and clearance adjustment, suitable for equipment overhaul and maintenance requirements
Precision High-precision raceway machining ensures a surface roughness Ra≤0.4μm, guaranteeing contact accuracy and transmission efficiency.
Applications: Suitable for planetary gear sets, differentials, and drive shaft supports in the gearboxes of heavy-duty equipment such as Cat 966M/972M loaders and D6T/D7E bulldozers, bearing combined radial and axial loads under heavy loads and impact vibration conditions.
Used in mining, infrastructure, and other applications, adapting to the low-speed, heavy-load power transmission requirements of transmission systems and extending the service life of transmission components.
Performance Characteristics: Single-row tapered roller structure, capable of simultaneously bearing radial and unidirectional axial loads, suitable for complex stress conditions in transmission components.
Separable design facilitates installation, maintenance, and clearance adjustment, conforming to Cat equipment’s high-precision assembly standards.
High-carbon chromium alloy steel material with carburizing and quenching process provides fatigue and impact resistance, extending service life by approximately 25% compared to ordinary bearings.
