| Code Segment | Technical Meaning |
|---|---|
| 511 | Designates a thrust ball bearing series with a flat housing washer and shaft washer. |
| 900 | Indicates a bore diameter of 900 mm. |
| M | Signifies that the bearing is manufactured to metric dimensions and tolerances. |
511/900 M Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: Engineered with a large contact angle and robust 52100 Chrome Steel components to handle substantial axial dynamic load ratings of 252,000 lbf and axial static load ratings of 2,340,000 lbf.
- Precision Ground Components: Features tight dimensional tolerances on the bore, outside diameter, and width for stable performance and precise alignment in heavy-duty assemblies.
- Durable Cage Construction: Utilizes a stainless steel cage for enhanced strength and corrosion resistance, ensuring reliable ball guidance and bearing integrity.
- Optimized for Low-Speed, High-Load Conditions: With a limiting speed of 0.4 x 1000 rpm, this bearing is ideal for applications where immense axial force is prioritized over rotational velocity.
- Wide Operating Temperature Range: Performs reliably in environments from -30°C to 110°C, suitable for various industrial settings.
511/900 M Bearing Typical Application Areas
- Heavy-Duty Industrial Machinery: Vertical pumps, large compressors, and extruders requiring high axial load support.
- Power Generation Equipment: Thrust positions in hydroelectric turbines and large gearboxes.
- Construction and Mining Equipment: Swing mechanisms and hoisting systems in cranes and excavators.
- Marine and Offshore Applications: Propulsion systems, stern tube bearings, and deck machinery.
- Large-Rotation Platforms: Slewing rings and turntables in industrial rotators and radar bases.
