|---|---|---|
| 51356 | Basic Model Number | Defines the core dimensions: 280mm bore, 440mm OD, 130mm width. |
| (No Suffix) | Open Seal Type | Indicates the bearing is unsealed, allowing for custom lubrication systems and high-speed capability with appropriate lubrication. |
51356 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: Engineered with a robust Chrome Steel cage and precision-ground components to handle substantial axial dynamic load ratings of 176,700 lbf and axial static load ratings of 866,863 lbf.
- Optimized for Thrust Loads: The thrust-specific design ensures maximum efficiency and longevity when subjected to pure axial forces, preventing premature failure common in misapplied radial bearings.
- Precision Tolerances: Features tight dimensional tolerances on the bore, outside diameter, and width for precise shaft and housing fits, contributing to stable operation and accurate alignment.
- Material Integrity: Constructed entirely from 52100 Chrome Steel, providing high hardness, wear resistance, and consistent performance within a temperature range of -30°C to 110°C.
- Versatile Lubrication: The open seal type provides flexibility for various lubrication regimens, which is critical for achieving the required limiting speed and service life in specific applications.
51356 Bearing Typical Application Areas
This high-capacity thrust ball bearing is critical in machinery and systems dominated by significant axial forces. Key industries and equipment include:
- Heavy-Duty Industrial Gearboxes and thrust reversers
- Vertical Pumps and compressors for supporting impeller weight and thrust
- Marine Propulsion Systems and stern tube arrangements
- Cranes and hoisting equipment for slewing ring applications
