513/630 Bearing Product Overview & Core Advantages
The 513/630 is a metric thrust ball bearing engineered for demanding applications requiring exceptional axial load capacity. This open-type bearing is designed to accommodate high thrust loads in a single direction, making it an ideal solution for heavy-duty machinery. Its robust construction from 52100 Chrome Steel ensures high durability and reliability in industrial environments. The bearing's substantial dimensions and high load ratings position it as a critical component for applications where space permits and extreme axial forces are present.
513/630 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Interpretation |
|---|---|
| 513 | Indicates the bearing series, specifying a thrust ball bearing design with a specific contact angle and internal geometry. |
| 630 | Specifies the bore diameter in millimeters (630 mm). |
| Open (Seal Type) | No integral seals or shields. This allows for custom lubrication systems and is suitable for applications where the bearing is integrated into a sealed housing. |
513/630 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The bearing's primary design focus is to support immense axial dynamic load ratings of 476,595 lbf and axial static load ratings of 3,507,019 lbf. This is achieved through its large contact area and robust construction.
- Robust Material Construction: Manufactured from 52100 Chrome Steel for both rings and balls, ensuring high hardness, wear resistance, and long service life under heavy loads.
- Chrome Steel Cage: The cage, also made from Chrome Steel, provides high strength and stability, ensuring proper ball guidance and reliable operation.
- Precision Tolerances: Features tight dimensional tolerances on the bore, outside diameter, and width, enabling precise mounting and optimal performance in high-precision applications.
- Wide Temperature Range: Operates effectively within a temperature range of -30°C to 110°C, offering versatility for various industrial environments.
