513/900 Bearing Product Overview & Core Advantages
The 513/900 is a large bore thrust ball bearing engineered for heavy-duty axial load applications in industrial machinery. This metric system bearing features an open design, requiring lubrication for optimal performance. Its primary advantage lies in its exceptional axial static load rating of 4,852,951 lbf, making it a robust solution for supporting significant thrust forces in a single direction. Manufactured from high-grade 52100 Chrome Steel for both rings and balls, it ensures durability and reliable operation within a temperature range of -30° to 110 °C.
513/900 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 513 | Indicates the bearing series, specifying a thrust ball bearing design. |
| 900 | Specifies the bore diameter of 900 mm. |
| (No Suffix) | Indicates an open seal type, meaning the bearing is not shielded or sealed and requires external lubrication. |
513/900 Bearing Structural Features & Performance Benefits
- High Load Capacity: The thrust-specific geometry and use of 52100 Chrome Steel components are optimized to handle extremely high axial dynamic and static loads, providing reliable support in demanding applications.
