CAT 2G-6478 is a bearing cover for Caterpillar heavy equipment drive axles/transmissions, compatible with specific tapered roller bearings. It is used to secure bearings, seal against dust, and bear part of the axial load. Key information is as follows:
Key Parameters
Item Details
Type: Split/Integral bearing cover (slightly different depending on the model), compatible with single-row tapered roller bearings, used in drive axle differentials or transmission bearing housings, providing positioning, dust protection, and preventing bearing movement.
Dimensions (Metric/Imperial): Inner diameter 146.05mm (5.750 inches), Outer diameter 203.2mm (8.000 inches), Thickness 25.4mm (1.000 inches), Bolt hole distribution circle diameter 174.625mm, compatible with 4×M16 bolts for Cat® Parts.
Material: Medium carbon alloy steel (4140), quenched and tempered, hardness… HRC28-32, tensile strength ≥1000MPa, possessing excellent strength and resistance to deformation, suitable for heavy-duty vibration conditions.
Precision: Inner diameter coaxiality ≤0.020mm, end face flatness ≤0.015mm, bolt hole position accuracy ±0.10mm, ensuring bearing operational accuracy after installation and reducing noise and wear.
Compatible Structure: Matches the corresponding bearing inner ring and rollers. During installation, sealant must be applied to prevent oil leakage. Use an O-ring (e.g., 123-4567) to achieve a seal, protecting the bearing from contaminants.
Suitable Scenarios: Suitable for drive axle differential bearings in Cat 950H and 962H loaders, gearbox output shaft bearings in D7R bulldozers, etc., used to fix the bearing outer ring, preventing axial movement under load, and providing sealing protection for the bearing.
This product is suitable for use during equipment overhauls/maintenances. When bearing caps show signs of deformation, cracks, damaged sealing surfaces, or stripped bolt holes, timely replacement is necessary to prevent equipment failure due to bearing loosening or oil leakage.
Performance Characteristics: Made of alloy steel, it boasts high strength and strong resistance to impact and vibration, making it suitable for the harsh operating conditions of heavy equipment and extending the service life of the bearing assembly.
High-precision machined inner diameter and end face ensure accurate bearing positioning after installation, reducing eccentric wear during operation and lowering equipment maintenance costs.
Standardized bolt hole and sealing groove design allows for compatibility with original seals and fasteners, facilitating easy installation, ensuring high interchangeability, and minimizing downtime.
