511/800-M Bearing Product Overview & Core Advantages
The 511/800-M is a metric single-direction thrust ball bearing engineered for demanding applications requiring exceptional axial load capacity. This heavy-duty bearing features a robust chrome steel construction and an open design, making it ideal for handling high thrust loads in low to moderate speed environments. Its primary advantage lies in its ability to support substantial axial dynamic and static load ratings (227,057 lbf and 2,023,280 lbf respectively), providing reliable performance in heavy machinery. The precise dimensional tolerances ensure stable operation and ease of integration into large-scale industrial equipment.
511/800-M Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 511 | Designates a single-direction thrust ball bearing with a flat seating washer. |
| /800 | Indicates the bore diameter of 800 mm. |
| -M | Signifies that the bearing is manufactured from copper-alloy machined cage material (as per provided "Chrome Steel" cage specification, this denotes a machined steel cage for enhanced strength). |
511/800-M Bearing Structural Features & Performance Benefits
- High Load Capacity: The bearing's robust design, utilizing 52100 chrome steel for both rings and balls, is optimized to withstand extreme axial static and dynamic loads, ensuring longevity under strenuous conditions.
- Machined Steel Cage (M): The chrome steel cage provides superior strength and guidance for the balls, contributing to stable operation and reliability, especially in applications with high inertial forces.
- Open Seal Type: The open design allows for versatile lubrication options, enabling the use of specialized grease or oil circulation systems to suit specific operational temperature ranges (-30° to 110 °C).
- Precision Tolerances: Tight dimensional control on the bore diameter, outside diameter, and width ensures precise shaft and housing fits, critical for alignment and load distribution in large assemblies.
511/800-M Bearing Typical Application Areas
The 511/800-M is ideally suited for heavy industrial machinery where significant axial forces are present. Key sectors include:
- Vertical Pumps and Turbines: For supporting the weight of rotating assemblies and hydraulic thrust.
- Large Industrial Gearboxes: To accommodate thrust loads within power transmission systems.
- Cranes and Hoisting Equipment: Used in slewing mechanisms to handle axial loads.
- Heavy-Duty Machine Tools: Particularly in vertical machining centers and boring mills.
- Marine Propulsion Systems: For managing thrust in large shaft lines.
