High Load Carrying Excavator Bearings 150BA182 Angular Contact Ball Bearing

150BA182 Angular Contact Ball Bearing For Excavators & Heavy Machinery

In the field of construction machinery and heavy-duty equipment, bearings have a significant impact on operational efficiency and durability. The 150BA182 bearing, meticulously crafted for harsh working conditions, has become a key component in heavy machinery such as excavators and cranes. Its precise dimensions, innovative structure, and excellent performance are highly favored in the industry.

The inner diameter of the 150BA182 bearing is 150mm, precisely designed to perfectly match the shaft diameter of specific components in equipment like excavators. This tight fit ensures a secure connection between the bearing and the shaft, preventing relative sliding during high-speed operation and under heavy loads.

The 182mm outer diameter provides sufficient structural strength to cope with various stresses in complex working conditions while matching the installation dimensions of equipment components. This ensures compactness and coordination of the entire mechanical system.

The 16mm width balances axial load-carrying capacity with space constraints. Within limited installation space, it effectively bears axial forces while maintaining compatibility with other components.

The 150BA182 bearing adopts a single-row angular contact ball bearing structure with significant advantages:

• Capable of bearing both large radial and axial loads simultaneously
• Approximately 40-degree contact angle enhances axial force resistance
• Reinforced inner and outer rings with excellent rigidity
• Optimized raceway curvature reduces wear and extends service life
• Available with steel cage for high-strength applications or brass cage for improved self-lubrication

Made of high-quality GCr15 chromium steel with excellent hardness, wear resistance, and fatigue resistance. After strict heat treatment, hardness reaches HRC60-65, maintaining performance during long-term heavy-load operation.

Advanced high-precision equipment and processes ensure dimensional accuracy and surface quality meet high standards. Special anti-rust treatment enhances corrosion resistance in harsh environments.

• High Load-Carrying Capacity: Strong dynamic and static load performance for heavy-load working conditions
• Good High-Speed Performance: Low friction coefficient and effective heat dissipation mechanisms
• Strong Stability and Reliability: Excellent sealing design protects against dust, moisture, and impurities

Crucial for bearing radial and axial loads during slewing process, ensuring smooth and precise operation of excavator upper structure.

Widely used in travel motors of excavators and loaders, efficiently transmitting power during equipment movement on various terrains.

Suitable for cranes (boom rotation) and bulldozers (transmission systems), providing reliable power transmission and operational stability.

With precise dimensional parameters, innovative structural design, high-quality material technology, excellent performance, and wide range of applications, the 150BA182 bearing has become an indispensable key component in the heavy construction machinery industry, providing reliable guarantee for efficient and stable equipment operation.
