511/1400 F Bearing Product Overview & Core Advantages
The 511/1400 F is a metric thrust ball bearing engineered for heavy-duty axial load applications. This bearing is specifically designed to accommodate high thrust loads in a single direction, making it an ideal solution for applications requiring robust axial support. Its large bore diameter of 1400 mm and substantial construction provide exceptional stability and load-carrying capacity. Manufactured from high-grade 52100 Chrome Steel for both rings and balls, it ensures long service life and reliable performance in demanding industrial environments.
511/1400 F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 511 | Indicates a thrust ball bearing with a flat seat on the housing washer. |
| /1400 | Specifies the bore diameter of 1400 mm. |
| F | Signifies a machined brass cage (based on standard nomenclature), though the specification lists a stainless steel cage for enhanced corrosion resistance. |
| Open (Seal Type) | The bearing is supplied without seals or shields, suitable for applications where external sealing is provided or where lubrication access is required. |
511/1400 F Bearing Structural Features & Performance Benefits
High Axial Load Capacity: With an impressive axial static load rating of 4,950,000 lbf and a dynamic rating of 409,500 lbf, this bearing is built to withstand extreme thrust forces. The use of a stainless steel cage provides superior strength and corrosion resistance compared to stamped cages, ensuring cage integrity under heavy load and in challenging environments.
Robust Construction & Dimensional Stability: The large bearing dimensions (1630 mm OD, 180 mm width) and tight dimensional tolerances contribute to precise alignment and stable operation. The specified chamfer dimension of 8 mm facilitates easier installation and prevents stress concentration.
Material Excellence: The rings and balls made from 52100 Chrome Steel offer high hardness and wear resistance, which are critical for the longevity of a thrust bearing under high load. The open design allows for efficient lubrication management tailored to the specific application needs.
511/1400 F Bearing Typical Application Areas
The 511/1400 F is typically deployed in heavy machinery and large-scale industrial systems where substantial unidirectional axial loads are present. Key application areas include:
- Vertical Turbines and Pumps
- Large Crane Slewing Rings
- Heavy-Duty Presses and Extrusion Equipment
- Mining and Construction Machinery
- Hydroelectric Power Generation Systems
