51460 Bearing Product Overview & Core Advantages
The 51460 metric thrust ball bearing is engineered for demanding thrust load applications requiring high capacity and robust construction. This open-type bearing is designed to accommodate heavy axial dynamic loads and exceptionally high axial static loads in a single direction. Manufactured from 52100 Chrome Steel for both rings and balls, it delivers superior durability and consistent performance in industrial environments. Its large bore diameter and substantial cross-section make it an ideal choice for heavy machinery where load capacity and reliability are paramount.
51460 Bearing Model Code Explained, Specifications & Naming Convention
| Code Element | Technical Significance |
|---|---|
| 51460 | Basic model number denoting a metric thrust ball bearing with a 300mm bore and 540mm outside diameter. |
| Open (Seal Type) | No integral seals, allowing for custom lubrication systems and higher speed potential with forced lubrication. Requires external sealing in contaminated environments. |
51460 Bearing Structural Features & Performance Benefits
- High Load Capacity: The bearing's robust construction and large contact area enable it to handle an axial dynamic load rating of 296,748 lbf and an exceptional axial static load rating of 1,540,840 lbf, making it suitable for the most demanding thrust applications.
- Dimensional Precision: Features tight tolerances on the bore, outside diameter, and width, ensuring precise fitment and reliable performance in critical machinery. The bore diameter tolerance of -0.035mm to 0 guarantees accurate shaft mounting.
- Material Integrity: Constructed entirely from 52100 Chrome Steel for rings, balls, and cage, providing high hardness, wear resistance, and long service life under heavy loads.
- Lubrication Flexibility: As an open bearing that requires lubrication, it offers flexibility in choosing greases or oils best suited for the specific application's speed, temperature, and environmental conditions.
