CAT 183-9519 is a Caterpillar single-row tapered roller bearing outer ring, suitable for differentials in the drive axles of loaders/bulldozers, used for radial support and axial positioning. Key information is as follows:
Key Parameters
Item Details
Type: Single-tapered bearing outer ring, suitable for single-row tapered roller bearings (such as the 183-9518 inner ring), provides raceways for the rollers, withstands radial and unidirectional axial loads, suitable for heavy-duty drive components such as differentials (Cat® Parts)
Dimensions (Metric/Imperial): Inner diameter 136.525mm (5.375 inches), outer diameter 184.15mm (7.250 inches), width 29.37mm (1.156 inches), suitable for corresponding inner ring and bearing housing mounting dimensions
Material: Bearing steel (AISI 52100), integrally carburized and quenched, surface hardness HRC60-64, core hardness… HRC30-35, tensile strength ≥1800MPa, excellent impact resistance and wear resistance.
Precision: Inner diameter raceway diameter tolerance ±0.015mm, raceway roundness ≤0.005mm, end face runout ≤0.010mm, ensuring contact accuracy with the rollers and reducing operating noise and wear.
Compatible Structure: Forms a complete tapered roller bearing with the 183-9518 inner ring, rollers, and cage. During installation, it must be paired with the inner ring to ensure consistent contact angles and withstand the combined loads of the transmission system.
Suitable Applications: Suitable for drive axle differential bearings in Cat 950G and 962G loaders, final drive planetary gear bearings in D6R bulldozers, etc., supporting the differential housing and planetary gear shaft, maintaining stable operation under heavy load and high-speed rotation conditions.
When the outer raceway shows signs of pitting, peeling, or edge chipping during equipment overhaul, it should be replaced simultaneously with the inner raceway and rollers to prevent damage to a single component from causing bearing assembly failure.
Performance Characteristics: High-hardness raceway surface with excellent wear resistance, suitable for high-speed rotation and impact load conditions in differentials, extending the service life of the bearing assembly.
The tapered surface design forms an optimal contact angle with the inner raceway, ensuring even load distribution, reducing localized stress concentration, and improving load-bearing capacity.
Standardized dimensions ensure high interchangeability with original inner raceways, rollers, and other components, facilitating maintenance and replacement, and reducing inventory and procurement costs.
