513/950 Bearing Product Overview & Core Advantages
The 513/950 is a large-bore, thrust ball bearing engineered for applications requiring exceptional capacity for axial loads. Designed to the metric system, this bearing is characterized by its massive dimensions and robust construction from 52100 Chrome Steel. Its primary function is to accommodate heavy unidirectional axial forces while operating at moderate speeds, making it a critical component in heavy-duty industrial machinery where high axial static load rating and axial dynamic load rating are paramount.
513/950 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation |
|---|---|
| 513 | Indicates the bearing series, signifying a thrust ball bearing design with an asymmetrical washer configuration. |
| /950 | Specifies the bore diameter of 950 mm. |
| Seal type: Open | The bearing is supplied without integral seals or shields, allowing for custom lubrication systems to be implemented for the specific application. |
513/950 Bearing Structural Features & Performance Benefits
- High Load Capacity: Manufactured from high-grade 52100 Chrome Steel for both rings and balls, this bearing is built to withstand immense axial static loads of up to 5,027,627 lbf and axial dynamic loads of 651,496 lbf, ensuring long-term reliability under extreme stress.
- Robust Cage Design: The Chrome Steel cage provides secure ball guidance and structural integrity, contributing to stable operation.
- Precision Tolerances: Features tight dimensional tolerances on the bore, outside diameter, and width, facilitating precise mounting and alignment in heavy machinery.
- Compliance & Safety: The bearing is ROHS and REACH compliant, meeting stringent international standards for restricted substances.
513/950 Bearing Typical Application Areas
This thrust ball bearing is designed for massive, slow-rotating equipment where the primary load is axial. Key applications include:
- Heavy-Duty Industrial Gearboxes
- Large Vertical Pumps and Motors
- Marine Propulsion Systems and stern tubes
- Hydraulic Turbines and wind turbine yaw systems
- Construction and Mining Equipment such as large boring machines and crane slewing rings
