514/630 Bearing Product Overview & Core Advantages
The 514/630 thrust ball bearing is a metric series component engineered for pure axial load applications demanding exceptional static load capacity. This open-type bearing is manufactured from high-grade 52100 Chrome Steel, ensuring superior strength and durability. Its defining characteristic is its massive axial static load rating of 3,793,651 lbf, making it an ideal solution for supporting extremely heavy axial loads in low-speed, high-stress environments. The robust construction and precise dimensional tolerances guarantee reliable performance and long service life in the most demanding industrial settings.
514/630 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 514 | Indicates the bearing series, specifically a thrust ball bearing with an asymmetrical spherical seating washer. |
| 630 | Specifies the bore diameter in millimeters (630 mm). |
| Open (Seal Type) | No integral seals or shields. This design allows for the implementation of custom, application-specific lubrication systems for optimal performance. |
514/630 Bearing Structural Features & Performance Benefits
- Exceptional Load Capacity: Engineered with a robust single-direction design, this bearing is optimized to handle immense axial static loads (3,793,651 lbf) and high axial dynamic loads (490,083 lbf), providing a reliable foundation for heavy machinery.
- High-Strength Material Construction: All critical components, including the rings, balls, and cage, are manufactured from 52100 Chrome Steel. This ensures high hardness, wear resistance, and consistent performance under heavy loads.
- Precision Tolerances: Features tight dimensional tolerances on the bore diameter, outside diameter, and width to ensure precise fitment, alignment, and stable operation within the assembly.
- Customizable Lubrication: The open design provides the flexibility for engineers to select the most suitable lubrication method and interval based on specific operational speed, temperature, and environmental conditions.
514/630 Bearing Typical Application Areas
This heavy-duty thrust ball bearing is specifically designed for applications involving very high axial forces and low rotational speeds. Key industries and machinery include:
- Vertical Turbines and Pumps
- Heavy-Duty Industrial Gearboxes
- Large Crane Slewing Rings
- Hydraulic Presses and Extrusion Equipment
- Mining and Construction Machinery (e.g., tunnel boring machines)
