514/670 Bearing Product Overview & Core Advantages
The 514/670 Thrust Ball Bearing is a heavy-duty metric thrust bearing engineered to accommodate exceptionally high axial static loads exceeding 4 million pounds-force. Its robust, open design is optimized for applications requiring massive thrust capacity in a single direction. Manufactured from high-grade 52100 Chrome Steel, this bearing delivers reliable performance and durability in demanding industrial environments, making it a critical component for high-load, low-speed machinery.
514/670 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 514 | Indicates the bearing series, signifying a thrust ball bearing with a specific internal design and load capacity profile. |
| 670 | Specifies the bore diameter in millimeters (670 mm). |
| Open (Seal Type) | The bearing is supplied without seals or shields, allowing for maximum lubricant flow and heat dissipation. This necessitates an external sealing solution and a defined lubrication regimen. |
514/670 Bearing Structural Features & Performance Benefits
- Unmatched Axial Load Capacity: The core design is singularly focused on handling immense axial static and dynamic loads (4,023,630 lbf and 526,952 lbf, respectively), providing robust support for vertical shafts and heavy rotating assemblies.
- Heavy-Duty Construction: All components, including the rings, balls, and cage, are crafted from 52100 Chrome Steel, ensuring high strength, wear resistance, and long service life under extreme stress.
- Precision Ground Dimensions: Tight tolerances on the bore diameter, outside diameter, and width ensure a precise fit and reliable performance within the assembly, contributing to overall system accuracy.
- Optimized for Low-Speed Operation: With a limiting speed of 0.33 x 1000 rpm, this bearing is engineered for applications where high load is the primary concern over rotational velocity.
514/670 Bearing Typical Application Areas
This thrust ball bearing is indispensable in heavy industries where massive axial forces are present. Key applications include:
- Vertical Turbines and Pumps
- Heavy-Duty Industrial Gearboxes
- Large Crane Slewing Rings
- Hydraulic Presses and Extrusion Equipment
- Mining and Construction Machinery
