| Open (Seal Type) | No integral seals or shields, allowing for custom lubrication systems and higher speed potential with appropriate lubrication. |
51436 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: Engineered with a large contact angle and robust construction to support substantial axial dynamic load ratings of 211,995 lbf and exceptional axial static load ratings of 631,713 lbf, ensuring reliability under heavy thrust forces.
- Precision Ground Components: Features tight dimensional tolerances on the bore diameter (180 mm), outside diameter (360 mm), and width (140 mm) for precise axial positioning and alignment in assembly.
- Optimized Material Selection: Utilizes 52100 Chrome Steel for rings, balls, and cage, providing high hardness, excellent fatigue life, and consistent performance across a temperature range of -30°C to 110°C.
- Custom Lubrication Flexibility: The open seal type design allows for the use of specialized lubricants tailored to specific operational needs, including high-temperature or extreme-pressure applications, though it requires a dedicated lubrication system.
51436 Bearing Typical Application Areas
- Heavy-Duty Industrial Presses: For applying and maintaining high axial forces in metal forming and stamping operations.
- Large Vertical Pumps and Compressors: To support substantial thrust loads generated by impellers in fluid handling systems.
- Marine Propulsion Systems: In thrust blocks to manage propeller-induced axial forces.
- Wind Turbine Gearboxes: For handling axial loads in power transmission stages.
- Construction and Mining Equipment: Within heavy machinery requiring robust thrust bearing support for axial loads.
