CAT 212-5026 is Caterpillar’s Debris Resistant Tapered Roller Bearing Cone, designed for use with the CAT 212-5027 Debris Resistant Tapered Roller Bearing Cone. It is suitable for heavy-duty engineering machinery transmission components. Key information is as follows:
Core Parameters
Item Details
Compatible Bearing Inner Diameter: Approximately 10.5 inches (266.7 mm), matching the 212-5027 outer ring to form a complete tapered roller bearing.
Width: Approximately 4.0625 inches (103.1875 mm), ensuring precise contact with the outer ring and rollers.
Material: Bearing-grade high-carbon chromium alloy steel, carburized and quenched, surface hardness HRC60-64, good core toughness, fatigue resistance, and wear resistance.
Anti-Chip Design: Special wear-resistant coating on the raceway surface, combined with an optimized sealing structure, prevents dust and debris intrusion, suitable for dusty environments.
Structure The inner ring assembly, integrating rollers and cage, features a separable design for easy assembly and clearance adjustment.
Applications: Suitable for final drives, axles, differentials, and other components in Cat bulldozers, loaders, and other heavy-duty equipment, bearing combined radial and unidirectional axial loads. Commonly found in D-series bulldozers and similar models.
Suitable for heavy-duty applications in dusty, high-impact, and high-vibration environments such as mining and construction, protecting the internal lubrication environment of the bearing and extending the service life of transmission components.
Performance Features: Anti-debris coating and sealing design effectively reduce impurities entering the raceway, reducing wear and extending service life by approximately 30% compared to ordinary inner rings.
High-precision raceway machining ensures good contact with the outer ring and rollers, reducing friction loss and improving transmission efficiency.
The separable structure facilitates installation, maintenance, and clearance adjustment, meeting the high-precision assembly requirements of Cat equipment.
