175-3770: Bearing – Cup(Debris Resistant)

CAT 175-3770 is Caterpillar’s Debris Resistant Tapered Roller Bearing Cup, designed for heavy-duty equipment drive systems. Its core feature is enhanced resistance to contamination under harsh operating conditions. Key information is as follows:

Core Parameters
Item Details
Matching Inner Ring
Typically matches tapered roller bearing inner rings with an inner diameter of approximately 10.5 inches (266.7 mm) (e.g., the corresponding CAT model inner ring)
Width
Approximately 4.0625 inches (103.1875 mm)

Material
Bearing-grade alloy steel, carburized and quenched, hardened surface, tough core, fatigue-resistant and wear-resistant

Debris Resistant Design
Special coating on the raceway surface + optimized sealing grooves prevent dust and debris intrusion, suitable for dusty environments

Structure
Monolithic outer ring, tapered raceway, separable from the inner ring for easy assembly and clearance adjustment

Application Scenarios
Compatible with Cat 793 This series of components, including differentials, axles, and final drives, for heavy-duty equipment such as mining trucks and large loaders, withstands combined radial and unidirectional axial loads, making them suitable for dusty, high-impact working conditions in mines, infrastructure projects, and other similar environments.

Used in transmission systems, these components protect the internal bearings from contaminants, maintain a lubrication environment, and extend the lifespan of transmission components.

Performance Features: Anti-debris coating and sealing design effectively reduce impurities entering the raceway, lowering wear and extending service life by approximately 30% compared to ordinary outer rings.

High-precision raceway machining ensures good contact with the inner ring and rollers, reducing friction loss and improving transmission efficiency.

Separable structure facilitates installation, maintenance, and clearance adjustment, meeting the high-precision assembly requirements of CAT equipment.
