BD175-6A Double-Row Angular Contact Ball Bearing For Excavators & Loaders
In the operation system of construction machinery and heavy-duty equipment, the performance of bearings is directly related to the overall operation efficiency and service life of the equipment. As a key component specially designed for harsh working conditions, the BD175-6A bearing plays an important role in excavators, loaders and other heavy-duty machinery with its precise size specifications, unique structural design and excellent performance.
Precisely Adapted Dimensional Parameters
- Inner diameter: 175mm - Precisely calculated to perfectly match the shaft diameter specifications of specific parts of equipment such as excavators. This precise matching ensures a tight combination between the bearing and the shaft, guaranteeing stable power transmission and supporting efficient equipment operation.
- Outer diameter: 230mm - Designed to provide sufficient structural strength for the bearing to cope with various stresses under complex working conditions while fitting with installation dimensions of relevant equipment parts. Ensures compactness and coordination of the entire mechanical system.
- Width: 35mm - Designed to balance axial load-carrying capacity with equipment space limitations. Effectively bears axial force while maintaining compatibility with other components in limited installation spaces.
Unique Structural Design
The BD175-6A bearing adopts a double-row angular contact ball bearing structure, which provides numerous advantages. The layout of double-row rolling elements increases the bearing area, enabling it to bear large radial loads and bidirectional axial loads simultaneously, meeting the complex force requirements of equipment such as excavators during operation.
This structure has high rigidity, effectively reducing bearing deformation during operation, ensuring equipment rotation accuracy, and improving operational stability and precision.
The inner and outer rings of the bearing adopt an integrated design, enhancing overall structural strength and stability. When facing impact and vibration, it maintains optimal working state and prolongs service life. The raceway is designed with special curvature to optimize contact stress distribution between rolling elements and raceway, reducing wear and improving bearing reliability.
High-Quality Materials and Exquisite Craftsmanship
- Bearing material: Made of high-quality GCr15SiMn bearing steel with high hardness, wear resistance and fatigue resistance. After strict heat treatment process, hardness reaches HRC60-65, maintaining performance in long-term heavy-load and high-frequency operation.
- Processing technology: Utilizes high-precision manufacturing equipment and advanced process technology to ensure dimensional accuracy and surface quality. Raceway and rolling elements processing accuracy reaches high levels, reducing friction and vibration during operation while improving rotation accuracy and operational stability. Surface undergoes special anti-rust treatment for enhanced environmental resistance.
Excellent Performance Advantages
High load-carrying capacity: Thanks to the structural design and material selection, the BD175-6A bearing has strong load-carrying capacity with high rated dynamic and static load levels, easily coping with huge loads generated during digging, handling and other operations.
Good high-speed performance: High-precision processing and optimized structural design enable low friction coefficient during high-speed operation, reducing energy loss. Good lubrication performance ensures effective heat dissipation, avoiding performance degradation due to excessive temperature.
Strong stability and reliability: Excellent sealing performance effectively prevents dust, moisture and other impurities from entering the bearing. Maintains stable operation even in high temperature, dusty and violently vibrating working conditions, reducing failure probability and maintenance costs.
Wide Application Scenarios
The BD175-6A bearing is mainly used in key parts such as the slewing mechanism and travel motor of excavators. In the slewing mechanism, it bears radial and axial loads generated during slewing, ensuring stability and accuracy of slewing action. In the travel motor, its high load-carrying capacity and good high-speed performance meet power transmission requirements during equipment movement.
Additionally, the bearing can be applied to corresponding parts of other heavy-duty construction machinery such as loaders and cranes, providing reliable operation in engineering fields including mines, construction and water conservancy.
With its precise dimensional parameters, unique structural design, high-quality material craftsmanship and excellent performance advantages, the BD175-6A bearing has become an indispensable key component in the field of heavy-duty construction machinery, providing solid support for efficient and stable equipment operation.
