513/670 Bearing Product Overview & Core Advantages
The 513/670 is a thrust ball bearing engineered for applications demanding exceptional axial load capacity and robust construction. This metric series bearing is characterized by its large bore diameter of 670 mm and is designed specifically to accommodate high thrust loads in a single direction. Manufactured from 52100 Chrome Steel for both rings and balls, it offers high durability and reliable performance in heavy-duty industrial environments. Its design is ideal for scenarios where managing substantial axial forces is the primary requirement.
513/670 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 513 | Designates the series, indicating a specific thrust ball bearing design with a high axial dynamic load rating. |
| 670 | Indicates the bore diameter in millimeters (670 mm). |
| Open (Seal Type) | The bearing is supplied without seals or shields, requiring an external sealing solution and a dedicated lubrication system for optimal operation. |
513/670 Bearing Structural Features & Performance Benefits
High Axial Load Capacity: The thrust-specific design enables this bearing to support an extremely high axial static load rating of 3,793,651 lbf and an axial dynamic load rating of 513,464 lbf, making it suitable for the most demanding applications.
Robust Construction: Utilizing 52100 Chrome Steel for all critical components (rings, balls, and cage) ensures high strength, wear resistance, and long service life under heavy loads.
Precision Tolerances: The specified bore and outside diameter tolerances ensure a precise fit, contributing to stable performance and alignment in the assembly.
Lubrication Requirement: As an open bearing, it requires a proper lubrication regimen. This allows for the use of specialized lubricants tailored to specific operational conditions, such as extreme temperatures ranging from -30° to 110 °C.
513/670 Bearing Typical Application Areas
This heavy-duty thrust ball bearing is typically employed in industries and machinery where massive axial loads are prevalent. Key applications include:
- Vertical Turbines and Pumps
- Heavy-Duty Industrial Gearboxes
- Large Crane Slewing Rings
- Marine Propulsion Systems
