513/750 Bearing Product Overview & Core Advantages
The 513/750 metric thrust ball bearing is engineered for heavy-duty axial load applications requiring exceptional reliability. This single-direction thrust bearing is characterized by its massive 750 mm bore diameter and robust construction, designed to accommodate extremely high axial static load ratings exceeding 4 million lbf. Its open design allows for customized lubrication strategies, making it a cornerstone component in the most demanding industrial machinery where pure thrust loads are paramount.
513/750 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Interpretation |
|---|---|
| 513 | Indicates the bearing series, defining its internal geometry and size profile for thrust applications. |
| 750 | Specifies the nominal bore diameter of 750 mm. |
| Open (Seal Type) | No integral seals or shields. This allows for high-volume lubrication and is suitable for applications where external sealing is provided or where heat dissipation is critical. |
513/750 Bearing Structural Features & Performance Benefits
- Superior Axial Load Capacity: The bearing's fundamental design is optimized to carry immense single-direction axial loads, with a dynamic rating of 554,154 lbf and a formidable static rating of 4,169,531 lbf, ensuring stability under extreme force.
- Robust Material Construction: Manufactured from 52100 Chrome Steel for both rings and balls, and a Chrome Steel cage, the bearing delivers high hardness, wear resistance, and long-term dimensional stability.
- Precision Ground Dimensions: Features tight tolerances on the bore, outside diameter, and width, facilitating precise mounting and optimal load distribution in heavy machinery.
- Customizable Lubrication: The open seal type provides the flexibility for advanced lubrication systems, which is essential for managing operational temperatures and extending service life in low-speed, high-load scenarios.
513/750 Bearing Typical Application Areas
This bearing is specified for applications dominated by severe axial forces. Key industries and machinery include:
- Heavy-Duty Industrial Gearboxes and large power transmission systems.
- Vertical Turbines and hydroelectric generator systems.
- Large-Scale Presses and extrusion machinery.
- Crane Slewing Rings and other heavy lifting equipment.
- Mining and Construction Equipment where immense thrust loads are encountered.
