511/900 F Bearing Product Overview & Core Advantages
The 511/900 F is a metric thrust ball bearing engineered for applications requiring exceptional axial load capacity in a single direction. Its robust design, featuring large bore and outside diameters, makes it ideal for supporting heavy thrust loads in demanding industrial environments. Manufactured from high-grade 52100 Chrome Steel for rings and balls, this bearing ensures high durability and reliable performance, offering a compact solution for high-load, low-speed applications.
511/900 F Bearing Model Code Explained, Specifications & Naming Convention
The model designation "511/900 F" can be broken down as follows:
- 511: Indicates a thrust ball bearing series with a flat seating surface on both washers.
- 900: Specifies the bore diameter of 900 mm.
- F: Signifies that the bearing is manufactured from case-hardening steel, contributing to its high load-carrying capacity and toughness.
511/900 F Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The bearing's design is optimized to handle very high axial dynamic load ratings of 252,000 lbf and axial static load ratings of 2,340,000 lbf, making it suitable for massive thrust forces.
- Robust Construction: Utilizes 52100 Chrome Steel for bearing rings and balls, providing excellent wear resistance and long service life. The stainless steel cage ensures cage integrity and reliable ball guidance.
- Precision Dimensions: Features tight tolerances on bore, outside diameter, and width, ensuring precise fit and stable operation in the assembly.
- Low-Speed Operation: With a limiting speed of 0.4 x 1000 rpm, this bearing is designed for applications where high load support is more critical than rotational speed.
- Wide Temperature Range: Operates effectively within a temperature range of -30°C to 110°C, accommodating various industrial operating conditions.
511/900 F Bearing Typical Application Areas
This thrust ball bearing is ideally suited for heavy-duty machinery and equipment, including:
- Vertical Turbines and Pumps
- Heavy-Duty Industrial Gearboxes
- Large Crane Slewing Rings
- Hydraulic Presses and Extrusion Equipment
- Mining and Construction Machinery
