511/950 F Bearing Product Overview & Core Advantages
The 511/950 F is a metric thrust ball bearing engineered for demanding applications requiring high axial load capacity and robust construction. This open-type bearing is designed to accommodate heavy thrust loads in a single direction, making it an ideal solution for high-load, low-speed machinery. Its significant axial static load rating and use of high-grade materials ensure exceptional durability and reliable performance in industrial environments.
511/950 F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 511 | Indicates the basic bearing type: a thrust ball bearing with a flat seating surface (non-self-aligning). |
| 950 | Specifies the bore diameter of 950 mm. |
| F | Signifies that the bearing is manufactured from case-hardening steel, enhancing the toughness and wear resistance of the bearing rings. |
511/950 F Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The single-direction thrust design and large contact angle are optimized to handle immense axial static load ratings of 2,700,000 lbf and axial dynamic load ratings of 299,250 lbf, providing reliable support for heavy vertical loads.
- Robust Material Construction: Components are manufactured from 52100 Chrome Steel for rings and balls, and a Stainless Steel cage, ensuring high strength, resistance to deformation under load, and excellent corrosion resistance.
- Precision Tolerances: Features tight dimensional tolerances on the bore, outside diameter, and width, ensuring precise fit and stable operation within the assembly.
- Open Design: The open seal type allows for easy re-lubrication and is suitable for applications where external sealing is provided by the surrounding housing.
511/950 F Bearing Typical Application Areas
This high-capacity thrust ball bearing is typically employed in heavy-duty industrial machinery, including:
- Vertical Turbines and Pumps
- Heavy-Duty Gearboxes
- Large Crane Slewing Rings
- Industrial Presses
- Marine Propulsion Systems
